RESUMEN Se presenta el caso clínico de una adolescente de 18 años de edad, quien se accidentó en una motocicleta y fue remitida a la Escuela de Medicina Dental de la ciudad de Torreón, Estado Coahuila de México para la colocación de implantes dentarios. El tratamiento ortodóncico incluyó 2 fases: inicial, con la instalación de una prótesis parcial removible provisional y correctiva, donde se colocó una aparatología fija superior e inferior mediante la técnica de Roth. Con este tratamiento fueron corregidas la maloclusión, la ausencia dentaria y la pérdida ósea. Se logró una transmigración dentaria y a los 22 meses de evolución, la paciente alcanzó una oclusión funcional.

ABSTRACT The case report of an 18 years adolescent is presented, who had an accident in a motorcycle and she was referred to the Dental Medicine School of Torreón city, Coahuila State in Mexico, for the placement of dental implants. The orthodontic treatment included 2 phases: initial, with the installation of a removable, provisional and corrective partial denture, where an upper and lower fixed appliance was placed using the Roth technique. Malocclusion, tooth absence and bone loss were corrected with this treatment. A dental transmigration was achieved and after 22 months of evolution, the patient achieved a functional occlusion.

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 Fundamento: la erupción dental es un proceso biológico de migración de un órgano dentario desde el período de formación del diente hasta que alcanza el plano de oclusión. Objetivo: determinar la relación entre el peso, la talla y el brote del primer molar permanente como eventos del crecimiento somático en niños de seis años. Métodos: estudio observacional descriptivo de corte transversal realizado en la escuela Antonio Maceo Grajales del municipio Cienfuegos, en el período comprendido entre los meses de septiembre 2020 a junio 2021, que incluyó 63 escolares. Los datos fueron obtenidos a través de fichas antropométricas. Se analizaron variables como edad, sexo, color de la piel, peso, talla y tiempo de erupción del primer molar. Los datos recopilados fueron ubicados en tablas estadísticas diseñadas al efecto con Excel XP y se utilizó como editor de texto Microsoft Word 2010. Resultados: al relacionar percentiles del peso para la talla, brote del molar número seis y sexo se apreció que 21 féminas con normopeso presentaban brotado el primer molar (33, 3 % del total de niños) y 13 varones normopesos, de un total de 25, no presentaban indicios del molar número seis en boca (20, 6 % del total). La talla se comportó dentro de los percentiles normales. Conclusiones: los niños de la muestra estudiada presentan retraso en el brote del primer molar permanente, sin que esto guarde relación con el peso y la talla. El retardo fue más observado en los varones.

ABSTRACT Foundation: dental eruption is a biological process of a dental organ migration from the period of tooth formation until it reaches the occlusion plane. Objective: determine the relationship between weight, height and the first permanent molar eruption as events of somatic growth in six-years-old children. Methods: descriptive cross-sectional observational study carried out at the Antonio Maceo Grajales school in the Cienfuegos municipality, from September 2020 to June 2021, which included 62 schoolchildren. The data were obtained through anthropometric sheets. Variables such as age, sex, skin color, weight, height and time of first molar eruption were analyzed. The collected data were located in statistical charts designed for this purpose with Excel XP and Microsoft Word 2010 was used as a text editor. Results: when relating percentiles of weight to height, eruption of molar number six and sex, it was observed that 21 females with normal weight had erupted the first molar (33.3% of the total number of children) and 13 normal weight males, out of a total of 25 , did not present signs of molar number six in the mouth (20.6% of the total). Height behaved within normal percentiles. Conclusions: the children in the sample studied have a delay in the first permanent molar eruption, without this being related to weight and height. The delay was more observed in men.

RESUMEN Los caninos se pueden encontrar en situación heterotópica: fosas nasales, seno maxilar, sínfisis mentoniana, o ectópicamente cerca de su asiento normal, pero en diferentes posiciones. Lo más frecuente es que presenten su eje oblicuo hacia mesial, generalmente en palatino o vestibular en el caso de los inferiores, y relativamente frecuente bilateral. La sintomatología es nula en la inclusión y el diente se diagnostica por otros hechos o existe apariencia clínica en el caso de enclavamiento. El abordaje ortoquirúrgico de caninos retenidos ha avanzado con los miniimplantes; esto ha llevado a realizar ajustes en las técnicas quirúrgicas, priorizando la tracción mediante la técnica VISTA para un posicionamiento adecuado en la arcada. Los miniimplantes mejoran la eficacia y precisión, destacando su relevancia en ortodoncia en conjunto con la cirugía oral. Anteriormente se llevaban a cabo diferentes técnicas; a nivel vestibular, se realizaban colgajos con reposición apical o técnicas poco recomendables, como la fenestración mucosa, pues esta podría producir problemas periodontales; por otra parte, a nivel palatino, se realizaba la descubierta de los caninos incluidos mediante un colgajo mucoperióstico (técnica de ventana quirúrgica), en el que se realiza una alveolotomía conductora. Por todo ello, ha de tenerse en cuenta que la apa-ratología fija ortodóntica proporciona una alternativa que evita la extracción de órganos dentales retenidos, a través de técnicas quirúrgicas mínimamente invasivas, que permiten mantener los caninos en la arcada dental y, por tanto, la armonía de las arcadas dentales.

ABSTRACT Canines can be found in heterotopic situation: nostrils, maxillary sinus, mentonian symphysis, or ectopically near their normal seat, but in different positions. Most frequently it presents its axis obliquely towards mesial, generally in palatine or vestibular in the case of the inferior ones, and relatively frequently bilateral. Symptomatology is null in the inclusion and the tooth is diagnosed by other facts or there is clinical appearance in the case of interlocking. The orthosurgical approach to retained canines has advanced with mini-implants; which has led to adjustments in surgical techniques, prioritizing traction using the VISTA technique for adequate positioning in the arch. Mini-implants improve efficiency and precision, highlighting their relevance in orthodontics in conjunction with oral surgery. Previously, different techniques were carried out: at the vestibular level, flaps with apical repositioning or techniques that were not recommended, such as mucosal fenestration, which could cause periodontal problems; on the other hand, at the palatal level, the included canines were uncovered by means of a mucoperiosteal flap (surgical window technique), in which a conductive alveolotomy was performed. Therefore, it should be taken into account that fixed orthodontic appliances provide an alternative that avoids the extraction of retained dental organs through minimally invasive surgical techniques.

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: 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: 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: 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 Introduction: premature loss of primary teeth is associated with reduced arch length and migration of contiguous and antagonist teeth. It can compromise the natural maintenance of the arch perimeter and the eruption of the successor tooth. Objective: to characterize the premature loss of primary teeth in school children. Methods: descriptive observational cross-sectional study in children of the Frank País elementary school belonging to the Pedro Borrás University Polyclinic, Pinar del Río municipality during the period October 2021 to June 2023. Universe: 200 children from first to fifth grade. Sample: intentional non-probabilistic sample, which included 113 children considering the inclusion and exclusion criteria. Absolute frequencies, percentages and non-parametric Chi-square test were used as summary measures. Results: there was a greater presence of girls (56,6 %) in the five - seven years age group (69 %). The most frequent causes of loss of temporaries were dental caries (52,2 %) and pulp necrosis (26,5 %) in both age groups. There was greater involvement of lower first molars (66,1 %). Root development of the substitute permanent tooth predominated in Nolla stages five and six (28,3 % and 48,7 %). The predominant anomalies resulting from tooth loss were decreased arch perimeter (80,5 %) and mesial migration of primary molars (63,7 %). Conclusions: premature loss of primary teeth is modifiable if dental care and attention to the child with deciduous dentition is assumed as a priority by the family from early stages of life.

RESUMEN Introducción: la pérdida prematura de dientes primarios se asocia a reducción de longitud del arco dentario y migración de dientes contiguos y antagonistas. Puede comprometer el mantenimiento natural del perímetro del arco y la erupción del diente sucesor. Objetivo: caracterizar la pérdida prematura de dientes temporales en escolares. Métodos: estudio observacional descriptivo de corte transversal en niños de la escuela primaria Frank País pertenecientes al Policlínico Universitario Pedro Borrás, municipio Pinar del Río durante el periodo octubre 2021 a junio 2023. Universo: 200 niños de primero a quinto grado. Muestra: intencional no probabilística, que incluyó 113 niños considerando los criterios de inclusión y exclusión. Como medidas de resumen se emplearon frecuencias absolutas, porcentuales y prueba no paramétrica de Chi cuadrado. Resultados: se registró mayor presencia de niñas (56,6 %) del grupo cinco-siete años (69 %). Las causas más frecuentes de pérdida de temporales fueron caries dental (52,2 %) y necrosis pulpar (26,5 %) en ambos grupos de edades. Hubo mayor afectación en primeros molares inferiores (66,1 %). El desarrollo radicular del diente permanente sucedáneo predominó en los estadios cinco y seis de Nolla (28,3 y 48,7 %). Las anomalías consecuentes de la pérdida dentaria que predominaron fueron disminución del perímetro del arco (80,5 %) y migración mesial de molares temporales (63,7 %). Conclusiones: la pérdida prematura de dientes temporales es modificable si se asume el cuidado dental y atención al niño con dentición decidua como una prioridad por parte de la familia desde etapas tempranas de la vida.

Abstract The aim of this study was to assess the factors associated with oral health-related quality of life in adolescents (OHRQoL). Individual data on adolescents were collected from a secondary database. OHRQoL was measured using the oral impact on daily performance (OIDP) scale. Individual- and city-level variables were selected to represent the structural and intermediate determinants of health. The individual covariates analyzed were sex, age, skin color, maternal education, household income, number of people per room in the housing unit, dental attendance, self-perception of dental needs, untreated dental caries, and gingival bleeding. The contextual variables included the allocation factor, the Human Development Index (HDI), Gini coefficient, illiteracy, unemployment, income, average number of emergency dental visits per inhabitant, access to a sanitary sewer system, garbage collection, primary health care coverage, oral health team coverage, and number of tooth extractions between selected dental procedures and supervised toothbrushing. Unadjusted and adjusted multilevel Poisson regression analyses were used to evaluate the relationship between contextual and individual variables with overall OIDP scores (STATA version 16.0) - rate ratio (RR) and 95%CI. The mean OIDP score was 0.72 and the prevalence was 31.8%. There was an association between supervised toothbrushing average and the outcome (RR 0.95; 95%CI 0.91–0.99). Moreover, adolescents who lived in municipalities with the highest average number of emergency dental visits per inhabitant showed a higher OIDP. Sex, maternal education, untreated dental caries, and gingival bleeding were associated with OIDP. In addition, intersectoral public policies focusing on the reduction of social inequalities should be on the agenda of policymakers and stakeholders. healthrelated related OHRQoL. .

ABSTRACT One of the most common dental procedures is tooth extraction; however, the bone defect resulting from the process is only partially restored, leading to considerable bone loss. To rehabilitate a fully or partially edentulous patient, we must handle these sites with delicate surgical procedures. There is a large literature presenting attempts to overcome the negative effects of a dental extraction, with the aim of reducing tissue volume loss or restoring the alveolar architecture. In this context, Partial Extraction Therapy (PET) represents a subgroup of interventions to prevent bone loss after extraction using the tooth itself to prevent alveolar bone loss. This literature review aims to make a survey of the published articles on PET, with an emphasis on socket shield technique, and to explain the other techniques such as root burial, pontic-shield and proximal socket-shield, their indications and counter indications in order to deepen the knowledge of these techniques. To identify the included or considered studies, we adopted a detailed search strategy for MEDLINE and Cochrane Library focused in the last 31 years, whose language was English, Spanish or Portuguese. This text presents an analysis of current data regarding the alternatives for alveolar preservation and the installation of immediate implants in these areas, presenting the possibility of a different surgical technique. However, due to the immaturity and lack of conclusive scientific evidence regarding the predictability of the procedures, it is considered that the use of the socket shield technique must be done in an extremely cautious way. however restored patient architecture context PET (PET burial ponticshield pontic socketshield, socketshield shield, socket-shield studies 3 years English Portuguese areas However way

RESUMO Um dos procedimentos odontológicos mais comuns é a extração dentária, contudo, , o defeito ósseo decorrente do processo é apenas parcialmente restaurado, levando a uma perda ossea volumétrica consideravel. Para reabilitar um paciente totalmente ou parcialmente desdentado, devemos manusear estes sitios com intervenções cirúrgicas delicadas. Há uma vasta literatura apresentando tentativas de transpor os efeitos negativos de uma extração dentária, com o objetivo de diminuir a perda volumétrica tecidual ou restaurar a arquitetura alveolar. Neste contexto, a Terapia de Extração Parcial (TEP) representa um subgrupo de intervenções para prevenir a perda óssea após exodontia, usando o próprio dente para prevenir a perda óssea alveolar. Essa revisão de literatura tem por objetivo fazer um levantamento dos artigos publicados sobre as TEP, com ênfase na técnica de socket shield, e explanar a cerca das demais técnicas como sepultamento radicular, pontic-shield e proximal socket-shield, suas indicações e contra-indicações, a fim de aprofundar o conhecimento dessas técnicas.

Este texto, apresenta uma análise de dados atuais a respeito das alternativas para a preservação alveolar e instalação de implantes imediatos nestas áreas, apresentando a possibilidade de uma técnica cirúrgica diferenciada. No entanto, devido a imaturidade e falta de comprovação cientifica contundente a respeito da previsibilidade dos procedimentos, considera-se que o emprego da técnica de socket shield deve ser feito de forma cautelosa. dentária contudo restaurado consideravel desdentado delicadas contexto TEP (TEP exodontia radicular ponticshield pontic socketshield, socketshield socket-shield contraindicações, contraindicações contra indicações, contra-indicações incluidos inclui considerados estrategia estrate gia ultimos u ltimos 3 anos ingles, ingles ingle s, s ingle?s portugues. portugues portugue s. portugue?s texto áreas diferenciada entanto considerase considera se cautelosa

Aim The study aimed to evaluate the association between oral health and academic performance and/or school absenteeism. Methods Electronic searches were performed of the PubMed, Web of Science, SCOPUS and LILACS/BVS databases. We included observational studies that evaluated the association between dental caries, tooth loss, dental pain or oral health status with school absenteeism or academic performance. The studies had to contain a representative sample of the population: schoolchildren, children or adolescents. After the removal of duplicates, the electronic searches produced 3,789 articles. Of these, 25 studies were included in the systematic review and 13 in the meta-analysis. Results Considering all the studies evaluated in the meta-analysis, seven articles satisfied 100% of the Joanna Briggs Institute Critical Appraisal checklist, and six contained between 90% and 75% positive answers. The pooled effects showed that the chances of school absenteeism were 31% higher in subjects with dental caries (OR 1.31; 95%CI 1.12-1.54). Students with fair/poor dental health had a 50% higher chance of suffering poor academic performance (OR 1.50; 95%CI 1.22-1.84) and 34% higher chance of having problems at school (OR 1.34; 95%CI 1.06-1.70). Students with a history of toothache had a 3.7 higher chance of being absent from school (OR 6.65; 95%CI 1.60-8.32) and 71% higher chance of missing class due to toothache (OR 1.71; 95%CI 1.15-2.56). Subjects with a history of toothache had a 2.5 times higher chance of suffering poor academic performance (OR 2.58; 95% CI 2.04-3.27). Conclusion Therefore, students with oral problems were more likely to take time off school and present inferior academic performance. andor PubMed Science LILACSBVS LILACS BVS databases loss population schoolchildren adolescents duplicates 3789 3 789 3,78 these 2 1 metaanalysis. metaanalysis meta analysis. analysis meta-analysis metaanalysis, analysis, 100 checklist 90 75 answers 31 OR 1.31 131 95CI 95 1.121.54. 112154 1.12 1.54 . 12 54 1.12-1.54) fairpoor fair 50 1.50 150 1.221.84 122184 1.22 1.84 22 84 1.22-1.84 34 1.34 134 1.061.70. 106170 1.06 1.70 06 70 1.06-1.70) 37 7 3. 6.65 665 6 65 1.608.32 160832 1.60 8.32 60 8 32 1.60-8.32 71 1.71 171 1.152.56. 115256 1.15 2.56 15 56 1.15-2.56) 5 2. 2.58 258 58 2.043.27. 204327 2.04 3.27 04 27 2.04-3.27) Therefore 378 78 3,7 10 9 1.3 121 1.121.54 11215 112 1.1 154 1.5 1.12-1.54 221 1.221.8 12218 122 1.2 184 1.8 1.22-1.8 061 1.061.70 10617 106 1.0 170 1.7 0 1.06-1.70 6.6 66 608 1.608.3 16083 160 1.6 832 8.3 1.60-8.3 17 152 1.152.56 11525 115 256 1.15-2.56 043 2.043.27 20432 204 2.0 327 3.2 2.04-3.27 3, 1. 1.121.5 1121 11 1.12-1.5 1.221. 1221 18 1.22-1. 1.061.7 1061 1.06-1.7 6. 1.608. 1608 16 83 8. 1.60-8. 1.152.5 1152 1.15-2.5 2.043.2 2043 20 2.04-3.2 1.121. 1.12-1. 1.221 1.22-1 1.061. 1.06-1. 1.608 1.60-8 1.152. 1.15-2. 2.043. 2.04-3. 1.121 1.12-1 1.22- 1.061 1.06-1 1.60- 1.152 1.15-2 2.043 2.04-3 1.12- 1.06- 1.15- 2.04-

ABSTRACT Objective: This retrospective study aimed to assess the predictability of Invisalign® aligners regarding rotational, mesio-distal and buccal-lingual tip movements. Methods: Two materials were included in the analysis - EX30, used until 2013; and SmartTrack, in current use. The study comprised 56 adult patients treated with Invisalign Comprehensive. Data sample were assessed on three sets of digital models; model 1 - initial, model 2 - predicted, and model 3 - achieved. Sixty reference points were marked in each dental arch, and two reference planes assisted the superimposition. The degree of rotation, mesio-distal and buccal-lingual tip was obtained via trigonometric calculations, through a previously published validated method. The accuracy of outcomes was compared according to the types of tooth movement and teeth groups,and the influence of predetermined variables on movement accuracy was also investigated. Results: Rotation and mesio-distal tip did not present any significant difference when comparing EX30 and SmartTrack groups. Only buccal-lingual tip presented a significant difference, incisor and canine groups treated with EX30 aligners presented an increase in accuracy (p= 0.007 and p = 0.007, respectively). For each additional degree planned for rotation movements, there was an increase of 0.35° in the discrepancy, and an increase of 0.40° and 0.41° for mesio-distal and buccal-lingual tip, respectively. EX30 and SmartTrack discrepancies were compared by multilevel linear regression. Conclusion: EX30 aligners reached higher accuracy for buccal-lingual tip in anterior teeth. However, for rotation and mesio-distal tip, SmartTrack and EX30 are similarly accurate. The total amount of planned movement has a significant impact on accuracy rates, with a decrease in accuracy for every additional degree.

RESUMO Objetivo: Esse estudo retrospectivo teve como objetivo aferir a previsibilidade dos alinhadores Invisalign em relação aos movimentos de rotação e inclinações mesiodistal e vestibulolingual. Material e Métodos: Foram incluídos dois materiais nessa análise: EX30®, utilizado até 2013; e SmartTrack®, atualmente em uso. Esse estudo avaliou 56 pacientes tratados com Invisalign Comprehensive. Os dados foram avaliados em três pares de modelos digitais; modelo 1 - inicial, modelo 2 - planejado, e modelo 3 - alcançado. Foram marcados 60 pontos de referência em cada arcada, sendo a sobreposição realizada com auxílio de planos de referência. O grau de rotação e inclinações mesiodistal e vestibulolingual foi obtido por cálculos de trigonometria, usando um método validado publicado anteriormente. Os resultados foram comparados de acordo com os tipos de movimento dentário e grupos de dentes, também foi investigada a influência de variáveis predeterminadas na confiabilidade dos movimentos. Resultados: Os movimentos de rotação e inclinação mesiodistal não apresentaram diferença estatística, quando comparados os grupos EX30® e SmartTrack®. Somente a inclinação vestibulolingual apresentou diferença estatisticamente significativa, sendo que os grupos de incisivos e caninos tratados com alinhadores EX30® apresentaram um aumento na previsibilidade(p= 0,007 e p= 0,007, respectivamente). Para cada grau adicional planejado para movimento de rotação, ocorreu um aumento de 0,35° na discrepância, e aumentos de 0,40° e 0,41° para as inclinações mesiodistal e vestibulolingual, respectivamente. As discrepâncias entre EX30® e SmartTrack® foram comparadas por regressão linear multinível. Conclusão: Os alinhadores EX30® alcançaram maior previsibilidade para a inclinação vestibulolingual em dentes anteriores. No entanto, para rotação e inclinação mesiodistal, SmartTrack® e EX30® apresentaram previsibilidade similar. A quantidade total de movimento planejado apresenta influência significativa nas taxas de previsibilidade, com diminuição na acurácia para cada grau adicional.

Abstract The aim of this systematic review was to answer the following question: “Does alendronate, a nitrogen-containing bisphosphonate, improve or impair alveolar socket healing after tooth extraction in animal models”? To this end, a systematic review of the literature was carried out in PubMed, Scopus, LILACS, Web of Science, as well as in the gray literature up to May 2023. Preclinical studies that evaluated alveolar healing after tooth extraction and the intake of sodium alendronate compared with placebo were included. Two investigators were responsible for screening the articles independently, extracting the data, and assessing their quality through the SYRCLE’s RoB tool for randomized trials in animal studies. The study selection process, study characteristics, risk of bias in studies, impact of alendronate on bone healing, and certainty of evidence were described in text and table formats. Methodological differences among the studies were restricted to the synthesis methods. The synthesis of qualitative results followed the Synthesis Without Meta-analysis (SWiM) reporting guideline. From the 19 included studies, five were considered to have low risk, three were of unclear risk, and eleven presented a high risk of bias. The studies were considered heterogeneous regarding alendronate posology, including its dosage and route of administration. Furthermore, a variety of animal species, different age ranges, diverse teeth extracted, and exposure or not to ovariectomy contributed to the lack of parity of the selected studies. Our results indicated that alendronate monotherapy negatively affects the early phase of wound healing after tooth extraction in preclinical studies, suggesting that the bone resorption process after tooth extraction in animals treated with alendronate might impair the bone healing process of the extraction socket. In conclusion, alendronate administration restrains bone resorption, thereby delaying alveolar socket healing . Future studies should be conducted to validate these findings and to better understand the effects of alendronate therapy on oral tissues. question Does nitrogencontaining nitrogen containing bisphosphonate models models” end PubMed Scopus LILACS Science 2023 independently data SYRCLEs SYRCLE s characteristics formats methods Metaanalysis Meta analysis SWiM (SWiM guideline 1 posology Furthermore species ranges extracted conclusion tissues 202 20 2

Abstract Accurate determination of the prevalence of erosive tooth wear (ETW) and associated risk factors in adolescents can inform clinical management guidelines. The aim of this analytical cross-sectional study was to estimate the prevalence, severity, and risk factors of ETW in adolescents aged 12–15 years in the municipality of Usaquén in Bogotá, Colombia. Two calibrated examiners clinically assessed ETW using Basic Erosive Wear Examination (BEWE) Index (range: 0–3). All tooth surfaces (excluding proximal) were scored to allow estimation of the Highest (0–3) and Total BEWE (sum of Highest BEWE score per sextant: 0–18) scores per patient. Sociodemographic characteristics, ETW risk factors, and caries severity (ICDAS-epi-merged) were evaluated, and their association with the presence of ETW (indicated by a Highest BEWE score of 2–3) was examined using preliminary analyses and logistic regression models. The study sample included 454 adolescents (mean age: 13.5±1.1 years; female: 61.7%), and the prevalence of ETW was 71.6%. The majority of participants exhibited a Highest BEWE score of 3 (58.0%) and a Total BEWE score ≤8 (84.3%). The preliminary analysis showed an association between the presence of ETW and age, caries, and brushing teeth before eating (p-value < 0.05). Risk factors for ETW included always brushing teeth before eating [adjusted Prevalence Ratio (PRa) 1.31, p-value=0.014], presence of extensive carious lesions (PRa 1.23, p-value = 0.024), male gender (PRa 1.14, p-value = 0.028), and age > 14 years (PRa 1.17, p-value = 0.009). Although ETW was highly prevalent, most Colombian adolescents exhibited low Total BEWE scores. ETW was associated with frequent fruit intake, age, toothbrushing habits, caries lesions, and sex.

RESUMEN Introducción: La odontología contemporánea requiere productos de alta calidad y fácil aplicación. Los biomateriales dentales entran en contacto con tejidos vivos por un tiempo determinado, para completarlos y mejorar su funcionamiento. Inicialmente, se consideraron ideales los productos biológicamente inertes y biocompatibles. Sin embargo, actualmente, los compuestos bioactivos resultan una alternativa prometedora. La respuesta biológica provocada por estos permite la formación de un enlace entre los tejidos y el material. Además, reducen la sensibilidad, la microfiltración y las caries secundarias Los materiales restauradores han evolucionado desde ionómeros de vidrio hasta ionómeros de vidrio modificados con resina, silicatos de calcio y composiciones restauradoras bioactivas, estéticas, como el aluminato de calcio y el silicato de calcio, que estimulan la formación de apatita. Estos nuevos compuestos, con propiedades remineralizantes y antibacterianas, pueden revertir la caries dental, inhibir la recurrente y recuperar minerales perdidos. El profesional estomatológico debe mantenerse actualizado en el conocimiento de estos materiales contemporáneos, para un tratamiento adecuado y la prevención de enfermedades bucodentales. Objetivo: Sistematizar información actualizada sobre las propiedades de los materiales bioactivos restauradores en la odontología contemporánea. Métodos: Se realizó una búsqueda en SciELO, MEDLINE/Pubmed, Scopus y Biblioteca Cochrane, entre octubre y noviembre de 2022. Se encontraron 25 documentos sin restricción de fecha de publicación y se incluyeron 17 artículos (88,2 % de actualización). Conclusiones: Los materiales bioactivos han tenido un impacto considerable en la odontología restauradora contemporánea. Han aumentado la calidad de de las restauraciones y reducido la recurrencia de caries.

ABSTRAC Introduction: contemporary dentistry requires high quality and easy application products. Dental biomaterials come into contact with living tissues for a certain time to complete them and improve their functioning. Initially, biologically inert and biocompatible products were considered ideal. However, bioactive compounds are a promising alternative nowadays. Biological response caused by these compounds allows the formation of a bond between the tissues and the material. In addition, they reduce sensitivity, microleakage and secondary cavities. Restorative materials have evolved from glass ionomers to resin-modified glass-ionomers, calcium silicates and aesthetic, bioactive and restorative materials such as calcium aluminate and calcium silicate which stimulate apatite formation. These new compounds with remineralizing and antibacterial properties can reverse dental cavities, inhibit recurrence and recover lost minerals. The stomatological professional must remain updated on these contemporary materials for adequate treatment and prevention of oral diseases. Objective: to systematize updated information on the properties of bioactive restorative materials in contemporary dentistry. Methods: a search was carried out in SciELO, MEDLINE/Pubmed, Scopus and the Cochrane Library between October and November 2022. A number of 25 documents were found without publication date restrictions and 17 articles were included (88.2% updated). Conclusions: bioactive materials have had a considerable impact on contemporary restorative dentistry. They have increased the quality of restorations and reduced the recurrence of cavities.

RESUMEN Introducción: La dentición y la curva de crecimiento son orientativas de la maduración del infante. Este conocimiento es de interés antropológico, demográfico, forense y paleontológico; permite diagnosticar, elaborar planes de tratamiento y prever pronósticos. Es útil tener presente el patrón de erupción promedio para determinar si hay adelantos o retrasos notorios, y se encuentra mayor variabilidad en la cronología que en la secuencia. En Cuba no han sido establecidos los estándares nacionales de orden y cronología de brote dentario. Objetivo: Describir los patrones del orden y cronología de brote de la dentición temporal. Métodos: Se realizó un estudio epidemiológico descriptivo de la dentición temporal en niños de la provincia de Villa Clara, entre los años 2014 a 2018. Mediante un muestreo polietápico aleatorio simple, se obtuvo una muestra de 520 niños entre 3 meses y 4 años, nacidos en la provincia, sin alteraciones del crecimiento general y craneofacial; se observó el brote y se calcularon los promedios ponderados para las edades. Resultados: Se encontraron diferencias para las edades; según Mayoral, Moyers y Águila, en más de la mitad, predominó la simetría y los dientes inferiores brotaron antes que sus homólogos superiores, excepto los caninos; el orden más frecuente fue: incisivos centrales, incisivos laterales, 1ros molares, caninos y 2dos molares. Conclusiones: El brote ocurrió por etapas; incluyeron determinados grupos dentarios separados por periodos de reposo y las secuencias polimórficas fueron encontradas en poca cantidad de sujetos. Se elaboró una tabla de edades de brote ajustada a la población villaclareña.

ABSTRAC Introduction: dentition and growth curve are indicative of the maturation of the infant. This knowledge is of anthropological, demographic, forensic and paleontological interest; it allows us to diagnose, develop treatment plans and predict prognoses. It is useful to keep in mind the average eruption pattern to determine if there are noticeable advances or delays, and greater variability is found in chronology than in sequence. In Cuba, national standards for the order and chronology of dental eruption have not been established. Objective: to describe the patterns of the order and chronology of eruption of deciduous dentition. Methods: a descriptive epidemiological study of deciduous dentition was carried out in children from Villa Clara province between 2014 and 2018. A sample of 520 children between 3 months and 4 years old who were born in the province without alterations in general and craniofacial growth was obtained through a simple random multistage sampling; the eruption was observed and weighted averages for ages were calculated. Results: differences were found for ages; symmetry prevailed in more than half according to Mayoral, Moyers and Águila as well as lower teeth erupted before their upper counterparts, except for canines; central incisors, lateral incisors, 1st molars, canines and 2nd molars was the most frequent order. Conclusions: tooth eruption occurred in stages; they included certain dental groups separated by periods of rest and polymorphic sequences were found in a small number of subjects. A table with the eruption ages adjusted to Villa Clara population was prepared.
