ABSTRACT Objective: To investigate associations/correlations between bone alterations and vitamin D status in children through data mining analyses based on observational studies. Material and Methods: Searches in PubMed, Scopus, Web of Science, and Embase databases were performed to recover studies, published until October 2022, with healthy children, which investigated the vitamin D status, related or not to undesirable bone alterations linked to bone quality (bone mineral density and bone mineral content), fracture or anthropometry. Country, study design, area of expertise (medicine, nutrition, dentistry, others), bone outcome, 25-hydroxyvitamin D data (serum or intake levels), the exams for bone diagnosis, and the results were analyzed in the VantagePointTM software. Results: Of 20,583 studies, 27 were included. The USA (n=9; 33.3%) had the highest number of publications. Cross-sectional (n=11; 40.7%), case-control (n=9; 33.3%), and cohort studies (n=7; 25.9%) contemplated the medicine and nutritional areas without any study in dentistry. Studies about bone quality (n=21; 77.8%), analyzed through dual-energy X-ray absorptiometry (DXA; n=14; 51.8%), with association (n=16; 59.2%) between the low serum levels of 25-hydroxyvitamin D and undesirable bone alterations (n=14; 51.8%) were the most prevalent. Conclusion: Most studies were conducted in the medical area and showed an association between low bone quality and low levels of 25-hydroxyvitamin D, verified through DXA.

ABSTRACT Objective: To compare the agreement of images in white light (WL), fluorescence (FL), and digital radiographs (DR), on the diagnosis and treatment decisions for occlusal caries lesions against a micro-CT gold standard. Material and Methods: Ten extracted third molars, with enamel and/or dentin caries (ICDAS 2-4), were included. Occlusal surface images were acquired with an intraoral camera (SoproLife®) in WL and FL modes. DR was obtained using an intraoral X-ray and a semi-direct digital system. A total of 780 images were needed, organized in a template, to be later examined by twenty-six dentists invited to compose the study. The Generalized Estimation Equations model was used to compare the proportions of the correct answers between the three methods and the gold standard. When significant, Bonferroni post-hoc test was used to identify differences (α=5%). Results: Most of the examiners were specialists (76.9%) with 14.5 years of experience. All diagnostic methods were similar and showed low agreement (DR 12.7%, WL 16.5%, and FL 16.5%) compared with gold standard caries diagnostic scores. Regarding treatment decisions, mean agreement for all diagnostic methods was higher (43.2%; p<0.001), and among all methods, WL (48.1%) and FL (51.2%) modes performed better than DR (30.4%, p<0.001). Conclusion: SoproLife® images could help clinicians to propose rational, minimally invasive treatments for occlusal caries lesions.

Resumo A tomografia computadorizada de feixe cónico (TCFC) fornece imagens sem sobreposição, sendo importante para o diagnóstico e avaliação da displasia cemento-óssea florida. Esta lesão fibro-óssea, que acomete o processo alveolar sem comprometer a vitalidade pulpar dos dentes, costuma ser assintomática, sendo incomum a expansão óssea, o rompimento cortical e a reabsorção radicular. Devido à característica avascular, procedimentos cirúrgicos são muitas vezes contraindicados. No presente caso, uma paciente do sexo feminino, 59 anos, apresentava dor no incisivo central superior direito. As radiografias panorâmica e periapical demonstraram displasia cemento-óssea florida em algumas regiões. O incisivo central superior direito apresentava imagem radiolúcida extensa, sugestiva de reabsorção radicular interna, mas sem lesão fibro-óssea. Para melhor avaliação e planeamento do implante, a TCFC foi realizada e demonstrou displasia cemento-óssea florida adjacente ao incisivo central superior direito, contraindicando a colocação do implante. Em outras regiões, a TCFC permitiu a identificação de características expansivas dessa lesão fibro-óssea.

Abstract Cone-beam computed tomography (CBCT) provides images without overlapping anatomical structures, which is important for the diagnosis and assessment of florid cemento-osseous dysplasia. This fibro-osseous lesion that affects the alveolar process without compromising the teeth’ pulp vitality is usually asymptomatic, and bone expansion, cortical disruption, and root resorption are uncommon. Due to its avascular characteristic, surgical procedures are often contraindicated. In this case, a 59-year-old female patient presented with a complaint of pain in the right maxillary central incisor. Panoramic and periapical radiographs showed florid cemento-osseous dysplasia in some regions. The right maxillary central incisor showed an extensive radiolucent image suggestive of root resorption but without fibro-osseous lesion. For better evaluation and implant planning, CBCT was performed and demonstrated florid cemento-osseous dysplasia adjacent to the right maxillary central incisor, contraindicating implant placement. In other regions, CBCT enabled the identification of the expansive features of this fibro-osseous lesion.

RESUMO Introdução: Em Ortodontia e Ortopedia Facial, o momento de início do tratamento pode ser crítico, e uma análise individual deve ser aplicada para promover um planejamento de tratamento favorável. No presente estudo, foram realizadas a avaliação individualizada da sutura palatina mediana (SPM) e medições no palato de adolescentes e adultos jovens tratados com expansão rápida da maxila (ERM). Descrição: Foram avaliados vinte e seis pacientes submetidos à ERM com aparelho dentossuportado (Hyrax). Os critérios de inclusão foram: idade mínima de 14 anos, apresentando todos os dentes posteriores, diagnosticado com discrepância transversa da maxila e com uma indicação clínica para expansão maxilar. A tomografia computadorizada de feixe cônico (TCFC) pré-tratamento desses pacientes foi avaliada para obter os estágios de maturação da SPM (MSPM), densidade da SPM (DSPM), comprimento do palato, espessura (anterior, intermediária e posterior) e área sagital. Resultados: Os estágios de maturação presentes foram C, D ou E; a densidade variou de 0,6 a 1, e foram determinados grupos de baixa (DSPM < 0,75) e alta densidade (DSPM ≥ 0,75). Indivíduos com maior DSPM apresentaram menor área sagital, em comparação com o grupo de densidade mais baixa. Indivíduos nos estágios D e E de MSPM apresentaram menor área sagital e espessura intermediária, comparados aos indivíduos no estágio C. Conclusão: Uma menor área sagital palatina foi observada nos grupos de alta DSPM e nos estágios D e E de MSPM.

ABSTRACT Introduction: In Orthodontics and Facial Orthopedics, the timing of treatment onset may be critical and individual analysis should be applied to promote a favorable treatment planning. In this study, individual analysis of midpalatal suture (MS) and palatal measurements were performed in teenagers and young adult patients treated with rapid maxillary expansion (RME). Description: Twenty-six patients submitted to RME with a tooth-supported appliance (Hyrax) were evaluated. The inclusion criteria were: minimum age of 14 years, presenting all posterior teeth, diagnosed with transverse maxillary discrepancy, and with a clinical indication for maxillary expansion. The pretreatment CBCT scans of these patients were assessed to obtain the stages of MS maturation (MSM); density ratio (MSD); and palatal length, thickness (anterior, intermediate and posterior) and sagittal area. Results: The maturation stages present were C, D or E; the density ranged from 0.6 to 1, and lower density (MSD < 0.75) and higher density (MSD ≥ 0.75) groups were determined. Individuals with higher MSD presented smaller sagittal area, compared to the lower density group. Individuals in D and E MSM stages presented smaller sagittal area and intermediate thickness, compared to stage C. Conclusions: Smaller palatal sagittal area was observed in the high MSD groups and in the stages D and E of MSM.

SUMMARY: The objective of this study was to investigate the prevalence and location of maxillary sinus septa prior to dental implant therapy in different age groups by cone beam computed tomography (CBCT) and identify the most helpful orthogonal plane for this purpose. CBCT scans of 200 patients were selected. The final sample was divided into four groups according to age: (1) 30-39 y.o.; (2) 40-49 y.o.; (3) 50-59 y.o.; (4) +60 y.o. Three calibrated examiners assessed the presence and location (anterior, middle, posterior) of sinus septa using all orthogonal slices. The prevalence of septa per region and plane was compared by chi-square test. Among 359 maxillary sinuses evaluated, it was observed at least one septum in 163 sinuses (45.4 %). Overall, the anterior region was the most prevalent. However, when the age groups were considered, the anterior region was only the most prevalent in groups 2 and 3. The middle and posterior regions were more prevalent in groups 4 and 1, respectively. In conclusion, the prevalence of maxillary sinus septa in patients who were candidate to dental implant therapy was notably high. It was observed that the anterior region of the sinus was the most prevalent and the axial slice was the most representative.

RESUMEN: El objetivo de este estudio fue investigar la prevalencia y localización del septo del seno maxilar antes del tratamiento con implantes dentales en diferentes grupos etarios, por medio de la Tomografía Computarizada de Haz Cónico (TCHC). Fueron seleccionadas TCHC de 200 pacientes. La muestra final fue dividida en cuatro grupos de acuerdo con la edad: (1) 30-39 años; (2) 40-49 años; (3) 50-59 años y (4) +60 años. Tres examinadores calibrados evaluaron la presencia y localización (anterior, media o posterior) del septo del seno maxilar usando todas las secciones ortogonales. La prevalencia del septo por región y plano fue comparada mediante el test x-cuadrado. Entre los 359 senos maxilares evaluados, fue observado por lo menos un septo en 163 senos (45,4 %). Generalmente la región anterior fue la más prevalente. Sin embargo, cuando fueron considerados los grupos etarios, solamente la región anterior fue la más prevalente en los grupos 2 y 3. Las regiones media y posterior fueron las más prevalente en los grupos 4 y 1, respectivamente. La prevalencia del septo del seno maxilar en pacientes que son candidatos a tratamiento con implantes dentales fue notablemente alta. Se observó que la región anterior fue la más prevalente siendo las secciones axiales las más representativas.

RESUMO A reabsorção intracoronária pré-eruptiva é uma lesão radiolúcida localizada na dentina, logo abaixo da junção amelo-detinária de dentes não irrompidos. É rara, assintomática e de etiologia idiopática, geralmente diagnosticada em exames radiográficos de rotina ou com fins ortodônticos. Uma abordagem conservadora com acompanhamento radiográfico é o tratamento recomendado até que o dente erupcione para ser feita a intervenção. Porém, em casos de sintomatologia ou progressão da lesão, aconselha-se a intervenção cirúrgica. Objetivo: Relatar o caso de reabsorção intracoronária pré-eruptiva, com uma abordagem conservadora mostrando a o acompanhamento clínico e radiográfico periódico desta condição. Paciente, sexo feminino, nove anos de idade, caucasiana, que compareceu a Clínica Odontológica para exame de rotina. Foi solicitada uma radiografia panorâmica inicial, sendo evidenciada uma radioluscência intracoronária no dente 45 ainda não erupcionado. Foi feito uma acompanhamento clínico e radiográfico até na total estabelecimento do dente acometido na cavidade oral. Conhecer a reabsorção intracoronária pré-eruptiva, associando sua provável etiologia e aspecto radiográfico, bem como sua prevalência e ocorrência e opções de tratamento, considerando uma abordagem conservadora, quando não houver sintomatologia, como tratamento recomendado.

ABSTRACT Pre-interruptive intracoronal resorption is a radiolucent lesion localized in dentin, immediately below the amelodentin junction of unerupted teeth. It is rare, asymptomatic, and of idiopathic etiology, generally diagnosed in routine radiographs or in those for orthodontic purposes. A conservative approach, with radiographic follow-up is the treatment recommended until the tooth erupts, and then the intervention is made. However, in cases with symptoms or progression of the lesion, surgical intervention is advisable. To report a case of pre-interruptive intracoronal resorption, with a conservative approach, showing the clinical and radiographic follow-up of this condition. The patient, a nine-year-old Caucasian girl, presented to the Dental Clinic for routine examination. An initial panoramic radiograph was requested, which showed an intracoronal radiolucence in tooth 45 that had not yet erupted. Clinical and radiographic follow-up was made until the affected tooth was completely established in the oral cavity. The treatment recommended for pre-interruptive intracoronal resorption is to have knowledge of the phenomenon, associate its probable etiology and radiographic aspect, as well as its prevalence, occurrence and treatment options, by considering a conservative approach when there are no symptoms.

The dentigerous cyst is one of the most frequently found in the jaws. They present themselves radiographically as radiolucent images and more commonly unilocular. They are usually observed at routine checkups or when investigating the presence of unerupted teeth. The dentigerous cyst occurs mainly in the first three decades of life, their growth is slow and asymptomatic. The third molars, as well as supernumerary teeth may be involved with the formation of a dentigerous cyst, but its pathogenesis is still not fully known. Decompression, marsupialization and enucleation are the main forms of treatment, but some criteria must be considered for the treatment plan, such as cyst size, age, proximity to noble anatomical structures and clinical importance of the tooth involved.In order to establish a correct diagnosis and treatment plan is essential to make use of complementary exams and now a days the cone beam computed tomography is the most complete and accurate method in diagnostic imaging used in these situations. Therefore, the aim of this study was to highlight, through the presentation of a clinical case, the importance of cone beam computed tomography in the diagnosis and treatment planning of a dentigerous cyst.

El quiste dentígero es una de las patologías óseas que más frecuentes en el maxilar y la mandíbula. Se evidencia radiográficamente como una imagen radiolúcida y unilocular en la mayoría de los casos. Generalmente es detectado en exámenes de rutina o cuando se investiga la presencia de dientes no erupcionados. El quiste dentígero aparece principalmente en las tres primeras décadas de vida, con crecimiento lento y asintomático. Los terceros molares,así como dientes supernumerarios, pueden estar relacionados con su formación, sin embargo, su etiopatología no es totalmente conocida. La descompresión, marsupialización y la enucleación son las principales formas de tratamiento, pero algunos criterios deben ser considerados, como tamaño del quiste, edad del paciente, proximidad con estructuras anatómicas nobles e importancia clínica del diente involucrado. Para que se establezca un correcto diagnóstico y plan de tratamiento es esencial la utilización de exámenes complementarios de calidad, siendo, actualmente, la tomografía computarizada de haz cónico el más completo y preciso método de diagnóstico por imagen empleado en estas lesiones. El objetivo de este estudio fue resaltar, por medio de la presentación de un caso clínico, la importancia de la tomografía computarizada de haz cónico en el diagnóstico y planeamiento quirúrgico de un quiste dentígero asociado a un diente no erupcionado.
