RESUMEN Introducción: Se han desarrollado materiales bioactivos para el recubrimiento pulpar directo con el objetivo de preservar la pulpa dentaria y mantener el diente por mayor tiempo en la cavidad oral. Objetivo: El objetivo de esta revisión fue evaluar la efectividad del uso de bioceramicos como material de recubrimiento directo pulpar para mantener la vitalidad pulpar en dientes primarios y permanentes con pulpitis reversible. Metodología: Se realizó una revisión sistemática con meta análisis. Se estudió el éxito en el tratamiento del mantenimiento de la vitalidad, el dolor postoperatorio y la decoloración. Se realizó una búsqueda Electrónica en las bases de datos: MEDLINE, EMBASE, COCHRANE, SCOPUS, LILACS, BBO. Se extrajeron los datos y se analizaron con Rev Man. Resultados: Se incluyeron ensayos clínicos aleatorizados en la cual se realizaron recubrimiento pulpar directo con silicatos tricalcicos comparado con otros materiales de recubrimiento. Comparando tres biocerámicos no se encontraron diferencias significativas en el mantenimiento de la vitalidad pulpar. En cuanto a la decoloración se observaron diferencias estadísticamente significativas a favor de Biodentine (p <0,001). Discusión: la relevancia clínica de estos hallazgos es discutible debido a su pequeña magnitud general y al alto riesgo de sesgo de los estudios incluidos.

ABSTRACT Introduction: Bioactive materials have been developed for direct pulp capping in order to preserve the dental pulp and keep the tooth longer in the oral cavity. Objective: The objective of this review was to evaluate the effectiveness of the use of bioceramics as direct pulp capping material to maintain pulp vitality in primary and permanent teeth with reversible pulpitis. Methods: A systematic review with meta-analysis was performed. Success in treating vitality maintenance, postoperative pain, and discoloration was studied. An electronic search was carried out in the databases: MEDLINE, EMBASE, COCHRANE, SCOPUS, LILACS, BBO. Data were extracted and analyzed with Rev Man. Results: Randomized clinical trials in which direct pulp capping with tricalcium silicates was performed compared with other capping materials were included. Comparing three bioceramics, no significant differences were found in the maintenance of pulp vitality. Regarding discoloration, statistically significant differences were observed in favor of Biodentine (p <0.001). Discussion: the clinical relevance of these findings is debatable due to their small overall magnitude and the high risk of bias of the included studies.

RESUMEN: Actualmente los factores que influyen en la supervivencia de los dientes trasplantados han podido ser controlados con el uso de la tecnología. El autotrasplante dental guiado ha logrado más predictibilidad y eficiencia, además, h a reducido los tiempos de transferencia desde la extracción hasta el trasplante. El objetivo de esta revisión es describir los protocolos de autotrasplante dental guiado, sus tasas de supervivencia y éxito publicados en la literatura actual. Esta revisió n fue realizada siguiendo la pauta PRISMA. La búsqueda se realizó en MEDLINE, Google Académico, ScienceDirect y SciELO, con los términos “autotransplant”, “autotransplantation”, “autotransplanting”, “dental”, “tooth”, “teeth”, “guided”, “guide” con filtro de publicación de 10 años. Se realizó evaluación de riesgo de sesgo mediante pautas Joanna Briggs Institute (JBI) a los estudios, incluyendo en esta revisión sólo con riesgo medio y bajo. Los datos de cada artículo se tabularon en una tabla realizada en el procesador de texto en línea “Google Docs”. Diez estudios cumplieron los criterios mencionados y fueron incluidos. Fueron evaluados un total de 37 pacientes entre 9 a 64 años. Los dientes donantes más frecuentes fueron premolares y terceros molares. En la mayoría de los casos los pacientes se encontraban sin antecedentes mórbidos de relevancia. El éxito fue evaluado mediante diversos criterios clínicos y radiográficos. Por otro lado, la supervivencia fue evaluada durante los seguimientos respecto a la permanencia del diente en boca. Este tipo de tratamiento no es muy conocido y los estudios incluidos fueron escasos, por otro lado, estos son de bajo nivel de evidencia (reportes de casos y serie de casos). Los protocolos evaluados difieren en algunas características, sin embargo, todos logran altas tasas de supervivencia y éxito. Igualmente, se presentan algunos fracasos, dónde los dientes debieron ser extraídos por movilidad e inflamación.

ABSTRACT: Currently, the factors that influence the survival of transplanted teeth have been controlled with the use of technology. Guided dental autotransplantation has achieved greater predictability and efficiency, and has also reduced transfer times from extraction to transplantation. The aim of this review is to describe the protocols of guided dental autotransplantation, their survival and success rates published in the current literature. This review was performed following the PRISMA guideline. The search was carried out in MEDLINE, Google Scholar, ScienceDirect and SciELO, with the terms "autotransplant", "autotransplantation", "autotransplanting", "autotransplanting", "dental", "tooth", "teeth", "guided", "guide" with a 10-year publication filter. Studies were assessed for risk of bias using Joanna Briggs Institute (JBI) guidelines, including only medium and low risk studies in this review. The data for each article were tabulated in a table created in the online word processor "Google Docs". Ten studies met the selection criteria and were included. A total of 37 patients between 9 and 64 years of age were evaluated. The most frequent donor teeth were premolars and third molars. In most cases the patients had no relevant morbid history. Success was evaluated by means of various clinical and radiographic criteria. On the other hand, survival was evaluated during the follow-ups with respect to the permanence of the tooth in the mouth. This type of treatment is not very well known, and the studies included were scarce; on the other hand, they are of a low level of evidence (case reports and case series). The evaluated protocols differ in some characteristics, however, all of them achieve high survival and success rates. There are also some failures, where teeth had to be extracted due to mobility and inflammation.

RESUMEN: El mesiodens es el diente supernumerario que se origina en la premaxila, siendo considerado el más prevalente o el más diagnosticado debido a las numerosas alteraciones que producen y que incluyen malposición de los dientes permanentes, formación de diastemas, retraso en la erupción de los incisivos anteriores superiores, y formación de quistes. La etiología de los mesiodens no está completamente comprendida, aunque se piensa que pueda deberse a la proliferación de la lámina dental u otros factores genéticos. El diagnóstico generalmente es tardío debido a que la mayoría permanece sin erupcionar, pudiendo generar complicaciones dentomaxilares que finalmente son el motivo de consulta de los pacientes. El quiste dentígero es un quiste odontogénico del desarrollo asociado a la corona de un diente incluido, numerario o supernumerario y su tratamiento es quirúrgico. El diagnóstico temprano y la planificación del tratamiento debe considerar una anamnesis minuciosa, un examen clínico e imágenes 3D. La cirugía debe consistir en la desinclusión del diente causal, la exéresis y legrado de la lesión, con o sin regeneración ósea inmediata del lecho quirúrgico con injerto. Se presentan dos casos de quiste dentígero asociado a un mesiodens que se diagnosticaron como hallazgo radiográfico. El plan de tratamiento consistió en evaluación y tratamiento endodóntico de los dientes desvitalizados, enucleción y legrado del quiste, junto a la desinclu sión del diente supernumerario, y seguimiento clínico y radiográfico en el largo plazo.

ABSTRACT: Mesiodens is the supernumerary tooth that originates in the premaxilla, considered the most prevalent or, the most diagnosed due to the multiple alterations that produce and that include malposition of the permanent teeth, formation of gaps, delayed eruption of the upper anterior incisors and cyst formation. The etiology of mesiodens is not fully established, although it is thought that it may be due dental lamina alteration or other genetic factors. Diagnosis is usually late because most remain unerupted, and can generate dentomaxillary complications that are ultimately the reason for patient consultation. The dentigerous cyst is a developmental odontogenic cyst associated with the crown of an included, numerary or supernumerary tooth and its treatment is surgery. Early diagnosis and treatment planning should consider a careful history, clinical examination, and 3D imaging. The surgery must consist of the disinclusion of the offending tooth, the exeresis and curettage of the lesion, with or without immediate bone regeneration of the surgical bed with a graft. Two cases of a dentigerous cyst associated with a mesiodens that were diagnosed as a radiographic finding are presented. The treatment plan consisted in evaluation and endodontic treatment of devitalized teeth, enucleation and curettage of the cyst, together with the disinclusion of the supernumerary tooth, and long-term clinical and radiographic follow-up.

RESUMEN Antecedentes: los pacientes con infecciones cervicales pueden presentar cuadros de extrema gravedad que ponen en riesgo su vida. Parece increíble que en pleno siglo XXI alguien muera por la infección de una muela, pero es real. Objetivo: describir los resultados con el diagnóstico y tratamiento de una serie de pacientes con infecciones de los espacios profundos del cuello de origen dentario, y establecer criterios para su manejo. Material y métodos: se realizó un estudio descriptivo y retrospectivo a partir de los registros en nuestra base datos entre septiembre de 2006 y junio de 2022. Se incluyeron sólo pacientes con infecciones cervicales de origen dentario. Se evaluaron las variables demográficas, las relacionadas al origen de la complicación, el tratamiento realizado y la evolución de los pacientes. Resultados: la muestra quedó conformada por 499 pacientes, con promedio de edad de 29 años (12- 70); 288 (57.7%) eran hombres. Consultaron en forma tardía 269 (53,9%) y se automedicaron en forma inicial 271 pacientes (54.3%). La mayoría no había recibido tratamiento de la pieza dentaria en el centro de atención primaria. Se realizó tratamiento quirúrgico 267 casos (53.5%), y el resto pudo tratarse de forma conservadora. La evolución fue favorable en 497 pacientes (99.6 %), y dos fallecieron por mediastinitis. Conclusión: las infecciones odontógenas deben ser diagnosticadas y tratadas apropiadamente en forma precoz a fin de evitar cuadros de extrema gravedad. Las campañas de educación poblacional y la instrucción de los médicos/odontólogos de centros de atención primaria y servicios de guardia podría mejorar esta problemática.

ABSTRACT Background: Patients with deep infections may present with extremely serious and life-threatening conditions. It is unbelievable that someone could die from a molar infection in the 21st century, but it is real. Objective: The aim of the present study is to describe the diagnosis and treatment results of a series of patients with odontogenic deep neck infections, and to establish criteria for the management of these infections. Material and methods: We conducted a retrospective and descriptive study based on records from a database from September 2006 to June 2022. Only patients with odontogenic deep neck infections were included. The demographic variables, those related to the origin of the complication, the treatment performed, and the patients’ progress were evaluated. Results: The sample was made up of 499 patients; mean age was 29 years (12-70) and 288 (57.7%) were men. Late visits and self-medication were recorded in 269 patients (53.9%) and 271 patients (54.3%), respectively. Most of them had not received treatment for the affected tooth at the primary healthcare center. Surgical treatment was performed in 267 cases (53.5%), and the rest were managed with conservative approach. The disease had a favorable course in 497 patients (99.6%) and two patients died of mediastinitis. Conclusion: Odontogenic infections should be adequately diagnosed and treated correctly and early to avoid extremely serious complications. Population-based educational campaigns and training for physicians and dentists working in primary care centers and emergency departments could improve this issue.

Since no recent study has been done about Afrikaans Fisher language the aim of this article is to give an updated linguistic description of this variety.1 Heiberg (1957) conducted a previous study. Varieties change all the time (D'Arcy, 2015:484) and Afrikaans Fisher language is no exception. Due to Covid-19 the researchers were unable to focus exclusively on subsistence fisher communities. Covid anxiousness led to the fact that many fishers did not want to take part in this qualitative study, in which, inter alia, questionnaires and interviews were used (Blume, 2023:35). All fishers indicating their willingness to participate were chosen as respondents if they were between 18 and 75 years of age. The sample of forty fishers is therefore small but is supplemented by various other sources. The areas covered were the coastal areas of the Eastern, Southwestern and Western Cape (Blume, 2023:35). Afrikaans Fisher language has been influenced by different languages, especially Dutch, Portuguese, Malay and English and is recognised as a variety due to several unique words and expressions. Stell, Luffin and Rakiep (2008:293) indicate that the initial Malay and Creole Portuguese of the 20th century led to the development of Muslim Afrikaans. Heiberg (1957:96) explains that the names of certain types offish have an Eastern origin and that they most probably show Malay or Portuguese influence, for example: daeraad: Portuguese, dorado, English dageraad (Blume, 2023:80). Dutch words like dòòdstròòm, kabbelau, omweer/onweer, platvisch (to mention a few) show remarkable similarities with Afrikaans (see Overdiep, 1940; Blume, 2023:108). The list below indicates examples of English influence: bait: something to lure the fish with bait caster: somebody who uses live bait to catch fish beaut: (noun) - a big or pretty fish beautiful: to describe a fish that is big or pretty bottom feeders: Amongst others steenbras, kapenaars, Rooi Roman, Miss Lucy, etcetera cast: fishing method using a hook, line, sinker and bait catch and release: catch fish and throw them back into the water chum, chumming: use bait to get a lot of fish in one place coffee grinder: a type of pulley drag, smooth drag: the breaks on the pulley - "die drag is smooth". dropshot: hook made of steel with a built-in sinker and bait which is used to catch fish edge - "daai edge gee": have a better chance of a catch happy days: exclamation of joy hook-up, double hook-up: when fish bite or when more than one fish is caught on one hook live bait: bait that is alive pink prawn: type of sand or mud prawn popper: artificial bait in the form of small fish pull: when you can see that a fish bites because of the movement of the line rocket: used to describe a fast fish - "Hy swem soos 'n rocket." run: when thefish bit but try to swim away with the hook and bait. The Afrikaans equivalents loop and hardloop are also used. single: when only one hook is used size: when a fish is legally big enough spinner: type of bait made of metal which turns around in the water tentacle: a type of bait, specifically octopus tentacle tooth wire: strong line used to catch fish trawl: method of pulling bait behind a boat trigger: "hongerkliertjie trigger": stimulation of the glands on certain types offish, usually when the chum method is used try wind: used instead of probeer inkatrol unbelievable: emotional exclamation wangle: manipulate tools to function as they should Hybrid (English and Afrikaans) forms are frequently used: The following English fish names are used: banded galjoen: also known as bastard galjoen, demba. belman: other names are baardman, belvis, tasselfish. bronze bream: alternative names are hottentot, das, Jan Bruin, John Brown, fat fish, copper bream, Nyizala, butterfish, etcetera. bronzy: variant of bronze bream. cob: kabeljou flatty: frequently used in the Eastern Cape instead of Kaapse stompneus. garrick: also called leervis, leerfish grunter: instead of knorhaan gruntertjie: instead of knorhaan Miss Lucy: instead of rooistompneus pig/pig nose: instead of witneussteenbras pyltail (stingray): instead of pylstert, skerpneuspylstert, blou pylstert, vlinderrog raggie: from ragged toothed shark instead of yellow shark, brown shark shad: (Afrikaans: elf) swart musselcracker: (Afrikaans: poenskop). This fish is also known as black biskop, witbek, black steenbras, saqomolo, swartbiskop. Most fishers use either musselcracker or poenskop. tiger: instead of tiger shark wit musselcracker: Also known as brusher, mussel crusher, silver steenbras, white biskop. Most fishers use musselcracker instead of biskop. yellowtail: Seriola lalandi (Blume, 2023:155-157). Fisher language differs in terms of degrees of standardisation as certain words also occur in the general vocabulary, as indicated in the latest Handwoordeboek van die Afrikaanse Taal (HAT). Some words are not standardised as they are English words, for example shad (instead of elf) or they consist of hybrid forms, containing English and Afrikaans elements, like raggie for a specific type of shark. Other words and expressions are not included in the HAT, probably as they are not so well-known or frequently used in the general lexicon, for example bonnie/ bonnietjie instead of bonito. Stylistic variation is evident in the usage of the frequently used informal word flattie instead of stompneus. The degree of education can also lead to variation, as in skuide for skuite and kiewe for kieue. Certain meaning distinctions relating to Fisher language do not occur in the HAT, for example mas used as a verb and the meaning distinction "small boat" at the lemma bakkie.

Afrikaanse visserstaal is deur verskillende tale beïnvloed, waaronder veral Nederlands, Portugees, Maleis en Engels en word as variëteit onderskei op grond van heelwat unieke woorde en uitdrukkings. Daar is min geografiese differensiasie tussen Oos-Kaapse en Wes-Kaapse visserstaal as gevolg van die dialekkontinuum (Blume, 2023). Woorde in Afrikaanse visserstaal verskil ten opsigte van gestandaardiseerdheid deurdat sommige woorde ook in die algemene woordeskat voorkom, soos in die nuutste HAT aangedui. Sommige woorde is nie gestandaardiseer nie aangesien hulle Engelse woorde is, byvoorbeeld shad, of 'n hibridiese vorm van Engels en Afrikaans is, byvoorbeeld raggie. Ander woorde en uitdrukkings is nie in die HAT opgeneem nie, waarskynlik omdat hulle nie so bekend/gebruiklik is in die algemene leksikon nie, byvoorbeeld bonnie/bonnietjie in plaas van die standaardwoord bonito. Stylvlakverskille kom voor by die Standaardafrikaanse woord stompneus teenoorflatty (informeel). Laasgenoemde word eerder onder die vissers gebruik. Dit geld ook vir die gebruik van visserman teenoor visterman. Enkele woorde in HAT6 bevat nie die visserstaal-betekenisonderskeiding nie, byvoorbeeld bakkie en mas as werkwoord.

ABSTRACT Objectives: This study aims to determine the prevalence of tooth agenesis and supernumerary teeth and characterize both anomalies in a Portuguese pediatric population. Methods: Clinical records of patients attending Pediatric Dentistry appointments in the Faculty of Dental Medicine of the University of Porto were consulted. Appointments from September 2020 to December 2021 were analyzed. For each patient, sex and age were recorded, along with any relevant data in their clinical history. Statistical analysis of the results was conducted using chi-square tests with a significance level of 0.05. The sample included 144 patients. Results: This study found a prevalence for tooth agenesis of 20.83% (11.81% excluding the third molars) and a prevalence for supernumerary teeth of 1.39%. The prevalence of agenesis was 26.1% for males and 16% for females. No association was established in this regard (p>0.05). The most affected teeth were the third molars, followed by the second premolars. The mandible had 52.63% of agenesis cases, but no association was found (p>0.05). Two cases of supernumerary teeth were found, both in male patients and in the second quadrant. No differences were inferred regarding sex (p>0.05). Conclusions: The results of this study contributed to the existing data regarding the prevalence of dental anomalies of number within a Portuguese population.

Foram analisadas consultas desde setembro de 2020 até dezembro de 2021. O sexo e a idade de cada paciente foram registados, assim como quaisquer dados relevantes constantes na história clínica. Foi realizada a análise estatística dos resultados com recurso a testes do Qui-Quadrado, com um nível de significância de 0,05. Foram incluídos 144 pacientes na amostra. Resultados: Este estudo encontrou uma prevalência de agenesias dentárias de 20,83% (11,81% excluindo os terceiros molares) e uma prevalência de dentes supranumerários de 1,39%. A prevalência de agenesias foi 26.1% no sexo masculino e 16% no feminino. Nenhuma associação foi estabelecida a este respeito (p>0,05). Os dentes mais afetados foram os terceiros molares, seguido dos segundos pré-molares. 52.63% das agenesias encontravam-se na mandíbula, mas nenhuma associação foi encontrada (p>0,05). Foram encontrados dois casos de dentes supranumerários, ambos no sexo masculino e no segundo quadrante. Não foram encontradas diferenças quanto ao sexo. (p>0,05). Conclusões: Os resultados deste estudo contribuíram para os dados existentes quanto à prevalência das anomalias dentárias de número na população portuguesa

ABSTRACT Background: The high prevalence of oral pathology in children encourages to gain further understanding on their manifestations and urgent nature, objective of the present study Methodology: Cross-sectional study that included patients aged <14 years of age who attended an emergency department over a one-year period. The relationship between the variables collected and oral pathology was analyzed. Results: Fifty-five patients were included, 45.5% girls, mean age 4.11 years (10 days to 13 years). Overall, mucosal pathology (74.5%) prevailed over dental ones, and lesions of infectious origin (54.6%) over the traumatic ones (14.5%). Dental pathology (50% toothache and 35.7% infections) was significantly associated with being >6 years (66.7 vs 10%), pain (40.7 vs 10.7%) and absence of fever (37.9 vs 11.5%). Mucosal pathology (61% infections: 53.7% viral and 31.7% due to herpangina) was significantly associated with being ≤6 years (60 vs 6.7%) and having fever (76.9 vs 17.2%). Six traumatic lesions on the mucosa and two on the teeth were observed; significantly more patients attended the emergency room within 24 hours (median =1 hour) than in the case of infection (100 vs 51.7%). Being ≤6 years was significantly associated with fever, mucosal pathology, mucosal infection, and herpangina, and being >6 years was associated with pain, previous antibiotic treatment and at discharge, and previous NSAID regimen. Conclusions: The analyzed pediatric oral pathologies treated in the emergency department are of mucosal and infectious origin. Dental disease prevail in children >6 years of age and mucosal lesions in those ≤6 years; no sex differences are observed.

RESUMEN Fundamento: La elevada prevalencia de la patología oral infantil incentiva a conocer sus manifestaciones y el carácter urgente de las mismas, objetivo del presente estudio. Metodología: Estudio transversal que incluyó pacientes de edad <14 años que acudieron a un servicio de urgencias durante un año. Se analizó la relación entre las variables recogidas y la patología oral. Resultados: Se incluyeron 55 pacientes, 45,5% niñas, edad media 4,11 años (10 días a 13 años). Globalmente, predominó la patología mucosa (74,5%) frente a la dentaria, y el origen infeccioso (54,6%) frente al traumático (14,5%). La patología dentaria (50% odontalgia y 35,7% infecciones) se asoció significativamente a edad >6 años (66,7 vs 10%), dolor (40,7 vs 10,7%) y ausencia de fiebre (37,9 vs 11,5%). La patología mucosa (61% infecciones: 53,7% víricas y 31,7% por herpangina) se asoció significativamente a edad ≤6 años (60 vs 6,7%); y fiebre (76,9 vs 17,2%). Se observaron seis lesiones traumáticas sobre la mucosa y dos en los dientes; significativamente más pacientes acudieron a urgencias antes de 24 horas (mediana =1 hora) que en caso de infección (100 vs 51,7%). La edad ≤6 años se asoció significativamente a fiebre, patología mucosa, infección de la mucosa y herpangina, y la >6 años se asoció a dolor, tratamiento antibiótico previo y al alta y pauta previa de AINE. Conclusión: La patología oral infantil atendida en el servicio de urgencias analizado fue de la mucosa y origen infeccioso, predominando la dentaria en >6 años y la mucosa en ≤6 años, sin diferencia por sexo.

ABSTRACT BACKGROUND AND OBJECTIVES: Bruxism is defined as an activity of the masticatory muscles, which is independent of the teeth presence, so it can occur in total edentulous patients and users of dental prostheses. In this sense, It is therefore necessary to know the clinical manifestations of bruxism in this population. The objective of this study was to evaluate the clinical manifestation and the presence of probable sleep and awake bruxism in a sample of users of full dentures treated at a teaching dental clinic in the city of Ribeirão Preto/SP. METHODS: The adopted sample consisted of 30 patients (mean age 72 years, 18 women/12 men). The following questionnaires were used to assess probable bruxism: Oral Behavior Checklist (OBC), Questionnaire of the American Academy of Orofacial Pain (AADO) and the Depression Anxiety and Stress Scale (DASS-21). The clinical assessment included the identification of wear on the prostheses, tongue indentations, bitten cheek and sensitivity in the masticatory muscles and temporomandibular joints. The data was analyzed using descriptive statistics. RESULTS: The average of use of the dentures were nine years. Six patients (20%) reported self-perceived sleep bruxism, and 11 (36%) reported self-perceived awake bruxism. OBC showed an average total score of 9.8 ± 6.2, with “teeth clenching” being the most described symptom. DASS-21 presented an average of 16.5, and stress, anxiety and depression were within normal limits. The most commonly reported symptoms in the AADO were headache, neck pain, pain and/or difficulty during jaw function and recent trauma to the head, neck or jaws. In the clinical evaluation, 15 (50%) patients had wear on prosthesis, only 2 (6%) had bitten cheek, none had tongue indentations, 4 (13%) had pain during palpation. CONCLUSION: Despite the limitations of the study (cross-sectional, small sample and absence of instrumental evaluation of bruxism), it is possible to conclude that a significant portion of users of total dentures presented probable bruxism, with tooth clenching being the main report and wear on the prosthesis the main clinical manifestation.

RESUMO JUSTIFICATIVA E OBJETIVOS: O bruxismo é definido como uma atividade da musculatura mastigatória, que independe da presença de dentes, portanto pode ocorrer em pacientes desdentados totais e usuários de próteses dentárias. Assim, é preciso conhecer como o bruxismo se manifesta clinicamente nessa população. O objetivo deste estudo foi investigar a presença do provável bruxismo de sono e de vigília em usuários de prótese total atendidos em uma clínica odontológica de ensino em Ribeirão Preto/SP. MÉTODOS: Uma amostra de conveniência foi composta por 30 pacientes (média de 72 anos, 18 mulheres e 12 homens). Os seguintes questionários foram utilizados para avaliar o provável bruxismo: Oral Behavior Checklist (OBC), Questionário da Academia Americana de Dor Orofacial (AADO) e o Depression Anxiety and Stress Scale (DASS-21). A avaliação clínica incluiu a identificação de desgastes nas próteses, língua dentada, bochecha mordiscada e sensibilidade nos músculos mastigatórios e nas articulações temporomandibulares. Os dados foram analisados por meio de estatística descritiva. RESULTADOS: A média de uso das próteses foi de nove anos. Seis indivíduos (20%) relataram bruxismo do sono e 11 (36%) relataram bruxismo de vigília. O OBC apresentou média de escore total de 9,8 ± 6,2, sendo “apertar de dentes” o sintoma mais descrito. O DASS-21 apresentou média total de 16,5, com valores de estresse, ansiedade e depressão dentro da normalidade. Os sintomas mais relatados no AADO foram cefaleia, dores no pescoço, dor e/ou dificuldade durante a função mandibular e trauma recente na cabeça, pescoço ou maxilares. Na avaliação clínica, 15 (50%) dos pacientes apresentaram desgastes na prótese, 4 (13%) dor por palpação, 2 (6%) bochecha mordiscada e nenhum (0%) língua dentada. CONCLUSÃO: Apesar das limitações deste estudo (corte transversal, amostra reduzida e ausência de avaliação instrumental do bruxismo) foi possível concluir que uma parcela significativa de usuários de próteses totais apresentou provável bruxismo, sendo o apertamento dentário o principal relato e desgastes na prótese a principal manifestação clínica.

SUMMARY: The dentogingival junction (DGJ) is an adaptation of the oral mucosa composed of epithelial and connective tissues intimately related with the mineralised tissues of the tooth. The histological evidence available is mainly based on studies in animals, separate evaluations of hard and soft tissues, and studies using conventional histological techniques that eliminate the enamel from preparations. The aim of this study was to carry out a review of the existing evidence on histological techniques available for study of the tooth and periodontium in conjunction in humans. A scoping review was carried out of the available literature referring to study of the tooth and the periodontium in conjunction in humans, in the Web of Science (WoS), EMBASE, Scopus and SciELO databases, using the terms "Histological Techniques"[Mesh]) and "Epithelial Attachment"[Mesh]. One hundred and fifty-nine articles were found, of which 54 were selected for full- text reading. Ten were finally included in the qualitative synthesis, and we applied the Anatomical Quality Assurance (AQUA) checklist for analysis the methodological quality of the selected articles. The results showed that the only articles with a low risk of bias in all five domains according to the AQUA criteria corresponded to Silva et al. (2011) and Agustín-Panadero et al. (2020). Finally, we conclude that the quality of the histological sections to observe tissues that simultaneously contain the tooth and the periodontium, is conditioned by the selected technique and by the care required in certain specific tasks during the histological processing of the samples.

RESUMEN: La unión dentogingival (DGJ) es una adaptación de la mucosa oral compuesta por tejidos epitelial y conectivo íntimamente relacionados con los tejidos mineralizados del diente. La evidencia histológica disponible se basa principalmente en estudios en animales, evaluaciones separadas de tejidos duros y blandos y estudios utilizando técnicas histológicas convencionales que eliminan el esmalte de las preparaciones. El objetivo de este estudio fue realizar una revisión de la evidencia existente sobre las técnicas histológicas disponibles para el estudio del diente y el periodonto en conjunto en humanos. Se realizó un scoping review de la literatura disponible referente al estudio del diente y el periodonto en conjunto en humanos, en las bases de datos Web of Science (WoS), EMBASE, Scopus y SciELO, utilizando los términos “Histological Techniques”[Mesh]) y "Epithelial Attachment"[Mesh]. Se encontraron 159 artículos, de los cuales 54 fueron seleccionados para lectura de texto completo. Diez fueron finalmente incluidos en la síntesis cualitativa, y se aplicó la lista de verificación Anatómica Quality Assurance (AQUA) para el análisis de la calidad metodológica de los artículos seleccionados. Los resultados mostraron que los únicos artículos con bajo riesgo de sesgo en los cinco dominios según los criterios AQUA correspondían a Silva et al. (2011) y Agustín-Panadero et al. (2020). Finalmente, concluimos que la calidad de los cortes histológicos para observar los tejidos que contienen simultáneamente el diente y el periodonto, está condicionada por la técnica seleccionada y por el cuidado requerido en ciertas tareas específicas durante el procesamiento histológico de las muestras.

Abstract The scope of this study was to analyze the spatial distribution of malocclusion (MO), estimate the prevalence and evaluate the associated factors in adolescents. It was a study with results of 5,558 adolescents aged 15 to 19 from the São Paulo Oral Health (SB) 2015 survey. The outcome was MO. Sociodemographic aspects, access to dental services, dental caries and tooth loss were the independent variables. A total of 162 municipalities in the state of São Paulo were included and spatial statistics techniques were applied. Hierarchical logistic regression models were performed. The prevalence of MO was 29.3%. There was a spread pattern between the types of MO and positive detachment (p<0,05). Non-white adolescents (OR=1.32, 95%CI: 1.24-1.42), with less years of schooling (OR=1.30, 95%CI: 1.22-1.42), with teeth extracted due to caries (OR=1.40, 95%CI: 1.03-1.88) were more likely to have MO. Adolescent access to dental consultation did not contribute to reducing the chance of developing MO, regardless of whether the dental consultation occurred less (OR=2.02, 95%CI: 1.65-2.47) or more than one year before (OR=1.63, 95%CI: 1.31-2.03). Thus, the occurrence of MO is unequally distributed in the state of São Paulo and associated with sociodemographic conditions, access to consultations and tooth loss due to caries.

Resumo O objetivo foi analisar a distribuição espacial da má oclusão (MO) em adolescentes, estimar a prevalência e avaliar os fatores associados. Estudo com dados de 5.558 adolescentes entre 15 e 19 anos de idade do inquérito - SB São Paulo 2015. O desfecho foi a MO. As variáveis independentes foram os aspectos sociodemográficos, acesso aos serviços odontológicos, cárie e perdas dentárias. Foram incluídos 162 municípios do estado de São Paulo e aplicadas técnicas de estatística espacial. Foram realizados modelos de regressão logística hierarquizada. A prevalência de MO foi de 29,3%. Houve um padrão de espalhamento entre os tipos de MO e correlação espacial positiva (p<0,05). Adolescentes não brancos (OR=1,32, IC95%: 1,24-1,42), com menor tempo de estudo (OR=1,30, IC95%: 1,22-1,42) e com dentes extraídos por cárie (OR=1,40, IC95%: 1,03-1,88) tiveram mais chances de apresentarem MO. O acesso dos adolescentes à consulta odontológica não contribuiu para reduzir a chance de apresentar a MO, independentemente de a consulta ao dentista ter ocorrido há menos (OR=2,02, IC95%: 1,65-2,47) ou há mais de um ano (OR=1,63, IC95%: 1,31-2,03). Assim, a ocorrência de MO é desigualmente distribuída no estado de São Paulo, e associada a condições sociodemográficas de acesso à consulta e perda dentária por cárie.

Abstract The scope of this study was to analyze the spatial distribution of malocclusion (MO), estimate the prevalence and evaluate the associated factors in adolescents. It was a study with results of 5,558 adolescents aged 15 to 19 from the São Paulo Oral Health (SB) 2015 survey. The outcome was MO. Sociodemographic aspects, access to dental services, dental caries and tooth loss were the independent variables. A total of 162 municipalities in the state of São Paulo were included and spatial statistics techniques were applied. Hierarchical logistic regression models were performed. The prevalence of MO was 29.3%. There was a spread pattern between the types of MO and positive detachment (p<0,05). Non-white adolescents (OR=1.32, 95%CI: 1.24-1.42), with less years of schooling (OR=1.30, 95%CI: 1.22-1.42), with teeth extracted due to caries (OR=1.40, 95%CI: 1.03-1.88) were more likely to have MO. Adolescent access to dental consultation did not contribute to reducing the chance of developing MO, regardless of whether the dental consultation occurred less (OR=2.02, 95%CI: 1.65-2.47) or more than one year before (OR=1.63, 95%CI: 1.31-2.03). Thus, the occurrence of MO is unequally distributed in the state of São Paulo and associated with sociodemographic conditions, access to consultations and tooth loss due to caries.

RESUMEN; Introducción: Existen procedimientos quirúrgicos que pueden generar una disminución en la duración de los tratamientos de ortodoncia (TO) mediante una aceleración del movimiento dental. La técnica más estudiada corresponde a la corticotomía clásica, la cual muchas veces es desechada por los pacientes debido a su invasividad. Es por esto que nacen las intervenciones quirúrgicas mínimamente invasivas (IQMI), tales como las micro osteoperforaciones (MOP) y la piezocisión, que buscan el mismo resultado, pero sin realizar colgajos de espesor total, otorgándole al paciente nuevas alternativas terapéuticas para acortar el tratamiento de ortodoncia. La evidencia al respecto aún es controversial, debido a que la certeza de la evidencia es baja o muy baja con relación a estos procedimientos. Métodos: Realizamos una búsqueda en Epistemonikos, la mayor base de datos de revisiones sistemáticas en salud, la cual es mantenida mediante el cribado de múltiples fuentes de información, incluyendo MEDLINE, EMBASE, Cochrane, entre otras. Extrajimos los datos desde las revisiones identificadas, analizamos los datos de los estudios primarios, realizamos un metaanálisis y preparamos una tabla de resumen de los resultados utilizando el método GRADE. Resultados y conclusiones: Identificamos 39 revisiones sistemáticas que en conjunto incluyeron 43 estudios primarios, de los cuales, 31 corresponden a ensayos aleatorizados. Concluimos que las intervenciones quirúrgicas mínimamente invasivas podrían aumentar la tasa de movimiento dental a las 12 semanas, la distancia total acumulada, la tasa de movimiento dental y reducir la duración total de tratamiento, pero la certeza de la evidencia es incierta. Además, podrían resultar en poca o ninguna diferencia sobre el índice gingival, la profundidad de sondaje y el índice de placa.

ABSTRACT: Introduction: There are surgical procedures that can generate a decrease in the orthodontic (OT) treatments duration through a Acceleration of tooth movement. The most studied technique corresponds to classical corticotomy, which is often discarded by patients due to its invasiveness. This is why minimally invasive surgical interventions (MISI) are born, such as micro osteoperforations (MOP) and piezocision, which seek the same result, but without making total thickness flaps, giving the patient new therapeutic alternatives to shorten orthodontic treatment. The evidence on this is still controversial, because the certainty of the evidence is low or very low in relation to these procedures. Methods: A search was performed using Epistemonikos, the biggest database for systematic reviews in health, which is maintained by screening of multiple sources of information, including MEDLINE, EMBASE, Cochrane, among others. Data from systematic reviews were extracted, and analysis of the primary studies was performed, including a meta-analysis and a summary of findings table using GRADE approach. Results and conclusions: We identified 39 systematic reviews that together included 43 primary studies, of which 31 correspond to randomized clinical trials. We conclude that minimally invasive surgical interventions could increase the rate of tooth movement at 12 weeks, distance total accumulated, the rate of tooth movement and reduce the total duration of treatment, but the certainty of the evidence is uncertain. In addition, they could result in little or no difference in gingival index, probing depth and plaque index.

RESUMEN Introducción: El tratamiento de los canales radiculares de molares temporales con pulpas infectadas ha sido ampliamente descrito y motivo de discusión por muchos años, no existiendo aún un consenso en cuanto al material de obturación. La pasta CTZ (cloranfenicol, tetraciclina y óxido de zinc más eugenol) acompañada de la Técnica de Endodoncia No Instrumentada ha mostrado una alta efectividad clínica y radiográfica para el tratamiento de molares temporales con compromiso pulpar. Se ha propuesto el reemplazo del componente Tetraciclina por Doxiciclina de la formulación, por las implicancias de un posible amelo-génesis imperfecta y la coloración en la corona de dicho componente. Objetivo. Evaluar la efectividad clínica de la pasta CDZ en el tratamiento endodóntico de dientes primarios necrosados con una técnica mínimamente invasiva. Metodología. Estudio de intervención en el que se incluyeron pacientes que presentaban dientes temporales con indicación de terapia pulpar y en quienes se utilizó la pasta CDZ. El éxito del tratamiento se midió por la desaparición de la sintomatología. Resultados. Se incluyeron en el estudio 76 pacientes entre 2 a 9 años. La eficacia del tratamiento con CDZ fue del 97,6% en 125 dientes. Conclusiones. Los hallazgos son comparables a los estudios que utilizaron el CTZ. Debido a las características biológicas del material, su bajo costo, fácil manipulación y excelentes resultados clínicos, se considera una opción en la terapia pulpar en dientes temporales, como una alternativa en el uso de programas de salud pública.

ABSTRACT Introduction: Treatment of root canals of primary molars with infected pulps has been widely described and has been the subject of discussion for many years, and there is still no consensus regarding the filling material. The CTZ paste (chloramphenicol, tetracycline and zinc oxide plus eugenol) accompanied by the Non-Instrumented Endodontic Technique has shown high clinical and radiographic effectiveness for the treatment of primary molars with pulp involvement. The replacement of the Tetracycline component by Doxycycline of the formulation has been proposed, due to the implications of a possible amelogenesis imperfecta and the coloration in the crown of said component. Goal. To evaluate the clinical effectiveness of CDZ paste in the endodontic treatment of necrotic primary teeth with a minimally invasive technique. Methodology: Intervention study in which patients with temporary teeth with an indication for pulp therapy and in whom CDZ paste was used were included. Treatment success was measured by the disappearance of symptoms. Results. 76 patients between 2 and 9 years old were included in the study. The efficacy of CDZ treatment was 97.6% in 125 teeth. Conclusions: The findings are comparable to studies using CTZ. Due to the biological characteristics of the material, its low cost, easy handling and excellent clinical results, it is considered an option in pulp therapy in primary teeth, as an alternative in the use of public health programs.

ABSTRACT Introduction: Bisphosphonates have an inhibitory impact on osteoclastic activity, reducing bone resorption. However, the influence of risedronate on tooth movement is not well-defined. Objective: This systematic review assessed the effect of risedronate intake on orthodontic tooth movement. A case report was also provided. Methods: Two independent reviewers searched six databases (PubMed, Web of Science, Ovid, Lilacs, Scopus, and Open Grey). The searches were carried out in April/2020, and an update was set in place in June/2023. Therefore, the searches considered a timeline from the databases’ inception date until June/2023, with no publication date and/or language restrictions. The clinical question focused on evaluating the orthodontic tooth movement and relapse movement (Outcome) in animals (Population) exposed to risedronate (Exposure), compared to control groups (Comparison). The Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines were applied, and the protocol was registered in PROSPERO (CRD42020168581). The risk of bias was determined using the Systematic Review Centre for Laboratory Animal Experimentation protocol (SYRCLE). Results: Two studies in rats and one in guinea pigs were included in the systematic review. The studies reported a decrease in orthodontic tooth movement, a reduction in the relapse movement, and a reduced number of positive tartrate-resistant acid phosphatase (TRAP) cells, with a significantly reduced number of bone gaps after the administration of risedronate in rats. A case report illustrated the effects of risedronate administration in one patient. Conclusion: Based on the systematic review, risedronate seems to impair orthodontic tooth movement and relapse due to a decrease in bone resorption cells.

RESUMO Introdução: Os bifosfonatos têm um impacto inibitório na atividade osteoclástica, reduzindo a reabsorção óssea. No entanto, a influência do risedronato no movimento dentário não está bem definida. Objetivo: Esta revisão sistemática avaliou o efeito do uso de risedronato no movimento ortodôntico dos dentes. Um relato de caso também é apresentado. Métodos: Dois revisores independentes pesquisaram seis bases de dados (PubMed, Web of Science, Ovid, Lilacs, Scopus e Open Grey), considerando o período de abril de 2020 até junho de 2023, sem restrições de data e/ou idioma de publicação. A questão clínica focou em avaliar o movimento ortodôntico dos dentes e movimento de recidiva (resultado) em animais (população) expostos ao risedronato (exposição) em comparação com grupos de controle (comparação). Foram aplicadas as Diretrizes Preferenciais para Revisão Sistemática e Metanálise (PRISMA) e um protocolo foi registrado no PROSPERO (CRD42020168581). O risco de viés foi determinado utilizando o protocolo do Centro de Revisão Sistemática para Experimentação em Animais de Laboratório (SYRCLE). Resultados: Dois estudos em ratos e um em porquinhos-da-índia foram incluídos na revisão sistemática. Os estudos relataram uma diminuição no movimento ortodôntico dos dentes, uma redução no movimento de recidiva e um número reduzido de células positivas à fosfatase ácida tartarato-resistente (TRAP) com um número significativamente reduzido de falhas ósseas após a administração de risedronato em ratos. Um relato de caso ilustrou os efeitos da administração de risedronato em uma paciente. Conclusão: Com base na revisão sistemática, o risedronato parece interferir no movimento ortodôntico dos dentes e na recidiva devido a uma diminuição nas células de reabsorção óssea.

Abstract Regular use of toothpaste with fluoride (F) concentrations of ≥ 1000 ppm has been shown to contribute to reducing caries increment. However, when used by children during the period of dental development, it can lead to dental fluorosis. Objective: In this study, we aimed to evaluate the in vitro effect of a toothpaste formulation with reduced fluoride (F) concentration (200 ppm) supplemented with sodium trimetaphosphate (TMP: 0.2%), Xylitol (X:16%), and Erythritol (E: 4%) on dental enamel demineralization. Methodology: Bovine enamel blocks were selected according to initial surface hardness (SHi) and then divided into seven experimental toothpaste groups (n=12). These groups included 1) no F-TMP-X-E (Placebo); 2) 16% Xylitol and 4% Erythritol (X-E); 3) 16% Xylitol, 4% Erythritol and 0.2%TMP (X-E-TMP); 4) 200 ppm F (no X-E-TMP: (200F)); 5) 200 ppm F and 0.2% TMP (200F-TMP); 200 ppm F, 16% Xylitol, 4% Erythritol, and 0.2% TMP (200F-X-E-TMP); and 7) 1,100 ppm F (1100F). Blocks were individually treated 2×/day with slurries of toothpastes and subjected to a pH cycling regimen for five days (DES: 6 hours and RE: 18 hours). Then, the percentage of surface hardness loss (%SH), integrated loss of subsurface hardness (ΔKHN), fluoride (F), calcium (Ca), and phosphorus (P) in enamel were determined. The data were analyzed by ANOVA (1-criterion) and the Student-Newman-Keuls test (p<0.001). Results: We found that the 200F-X-E-TMP treatment reduced %SH by 43% compared to the 1100F treatments (p<0.001). The ΔKHN was ~ 65% higher with 200F-X-E-TMP compared to 1100F (p<0.001). The highest concentration of F in enamel was observed on the 1100F treatment (p<0.001). The 200F-X-E-TMP treatment promote higher increase of Ca and P concentration in the enamel (p<0.001). Conclusion: The association of 200F-X-E-TMP led to a significant increase of the protective effect on enamel demineralization compared to the 1100F toothpaste.
