Objetivos: Como o rastreio da baixa densidade mineral óssea (DMO) sistêmica pode ser realizado por meio da radiografia panorâmica (RP), a procura por outros sinais detectáveis na RP que possam aumentar a taxa de pacientes indicados corretamente para o exame de densitometria óssea (DXA) ainda é necessária. Este estudo tem como objetivo correlacionar a baixa densidade DMO com o Índice de Massa Corpórea (IMC) e as alterações visíveis na RP: processo estiloide alongado, índice cortical mandibular (ICM) e número de dentes. Material e métodos: Foram utilizadas RPs de 23 pacientes que possuíam exame de DXA, para cada um, três examinadores com níveis diferentes de expertise (iniciante, experiente e expert) os classificaram de acordo com o ICM; o processo estiloide, como normal ou alongado; o número de dentes; e o IMC. Resultados: Foi observada correlação significante entre o ICM e o DXA apenas para o observador expert (r=-0,47). Para as outras variáveis (processo estiloide alongado, número de dentes e IMC) não houve correlações significantes. A concordância inter examinador foi de 0,50 para o observador expert e iniciante, 0,27 para experiente e expert e de 0,58 entre experiente e iniciante. A correlação intraexaminador foi de 0,77 para o expert, 0,48 para o iniciante e de 0,28 para o observador experiente. Conclusão: O ICM apresentou correlação significante com a baixa densidade mineral óssea, porém não foram encontradas evidências da relação de baixa densidade óssea com outros sinais detectáveis na RP.

Introdução: A sequência de Pierre Robin é uma tríade de anomalias caracterizada por micrognatia, glossoptose e fissura palatina. Estão descritas na literatura algumas modalidades de tratamento para melhorar a qualidade de vida dos pacientes com esta síndrome, como a distração óssea. Objetivo: Este artigo científico objetivou demonstrar a possibilidade de utilização da distração óssea na correção das anomalias advindas desta alteração. Materiais e métodos: Realizou-se uma busca de artigos em bases de dados eletrônicos e foram selecionados artigos escritos nos idiomas inglês e português, cujos temas abordados iam de encontro com o proposto por este trabalho e auxiliavam em sua produção. Resultados: Indivíduos com a Sequência de Pierre Robin apresentam características funcionais e estéticas comprometidas, afetando, consequentemente, as suas qualidades de vida. Conclusão: Concluiu-se que para uma reabilitação e um tratamento adequado, a técnica da distração óssea se mostrou muito eficaz. Cabe ressaltar a necessidade essencial de uma equipe multidisciplinar em atuação.

Objetivo: Identificar a presença de recidiva após o ato cirúrgico de pacientes diagnosticados com tumor de glândula salivar. Métodos: Os dados foram coletados no Hospital de Câncer de Pernambuco, Recife, Brasil, através de um formulário padrão com base nos prontuários clínicos. Foram coletadas informações sobre idade, sexo, tipo de tumor de glândula salivar, recidiva local, estágio, local primário e tipo de tratamento. Os dados foram descritivos e analisados com nível de significância de 5% (p < 0,05). Resultados: Dos 55 prontuários que fizeram parte da amostra do estudo, 51% correspondem ao sexo masculino. A média de idade geral foi de 55 anos, com a faixa etária variando entre 13 e 90 anos. O adenocarcinoma (SOE) foi o mais prevalente (n = 17), seguido do carcinoma adenoide cístico (CAC) (n = 14; 25,5%). Dentre todos os sítios, o mais comum foi a glândula parótida (n = 29; 53%). 61,8% (n = 34) dos pacientes não apresentaram metástase à distância. Entretanto, 38,18% (n = 21) apresentaram, sendo 14,55% (n = 8) com metástase em osso. 34,55% (n = 19) dos pacientes tiveram recidiva com apenas 1 ano após o diagnóstico. A neoplasia com maior taxa de recidiva foi o SOE, apresentando 30,91% (n = 17); o CAC foi o segundo maior com 25,45% (n = 14). Conclusão: O sexo masculino perfez a maioria dos casos; houve um predomínio de acometimento na glândula parótida; as neoplasias mais frequentes foram o SOE e o CAC; metástase à distância ocorreu em 38,18% (n = 21), sendo o osso o local mais acometido; a cirurgia com radioterapia adjuvante (n = 15) foi o tratamento de eleição.

This study sought to investigate the effect of the field of view (FOV) on linear measurements of cone beam computed tomography (CBCT) images. Methods: In this in vitro study, five dry human skulls were used. After using red wax to simulate soft tissue, the skulls were scanned using Galileos CBCT scanner (Sirona, Bensheim, Germany) with exposure parameters of 85 kVp and 21 mAs and voxel size of 0.280 mm; once with FOV of 15 cm × 8 cm and once again with 15 cm × 15 cm. The measured distances were the distance between the center of the bilateral mental foramen in the axial view (MM), the distance between the alveolar crest and the mandibular inferior border in the sagittal view on the midline (CB), and the depth of the socket of the left mandibular central incisor (L1). Descriptive statistics as well as Pearson’s correlation coefficient were used for statistical analysis (α = 0.05) using SPSS software (v. 25, IBM, NY, USA). Results: The measurements obtained with small and large FOV and with the dry skull were not significantly different (p > 0.05). The measurements obtained in small FOV had excellent correlation coefficient when compared with those obtained with the dry skull, with values of 0.890 for MM, 0.954 for CB, and 0.921 for L1 (p < 0.001). The measurements in large FOV also had excellent correlation coefficient when compared with those on the dry skull, with values of 0.894 for MM, 0.949 for CB, and 0.902 for L1 (p < 0.001). Conclusion: According to our findings, linear measurements obtained by CBCT scans in small and large FOVs were not significantly different than those on dry skulls. Since the linear measurements are accurate regardless of FOV size, selection of FOV must be based on patient factors, such as area of interest and radiation dose.

There are some theories regarding the emergence of dentigerous cysts. Among them, one claims they originate from the separation of the follicle in the crown of an erupted tooth, and another, that fluid accumulates between the crown and the reduced epithelium. Even with the existing research, its etiopathogenesis still remains unknown. Cysts can be treated in several ways, among them: enucleation, marsupialization, decompression, cryotherapy, endoscopy, and their combinations. Objective: To review the literature on dentigerous cyst treatment. Material and methods: This is a narrative literature review of articles written in Portuguese and English, and published from 2011 to 2021, which are available at the SciELO, BVS, and PubMed databases. Conclusion: We found that cyst enucleation is considered the treatment of choice whenever feasible, but since this technique destroys a significant amount of tissue, other more conservative options can be used. However, the adequate technique will vary according to the characteristics of the lesion and the patient.

Medication-related osteonecrosis of the jaw (MRONJ) is a relatively rare condition with high morbidity. In this study, we report the management of two recalcitrant cases of MRONJ in the mandibles of two older women who received treatment with alendronate for osteoporosis. Sequestrectomies, combined with antimicrobial photodynamic therapy (aPDT) and photobiomodulation (PBMT), were performed in both patients. During perioperative and weekly postoperative aPDT sessions, a diode laser treated three anatomical points by emitting a continuous gallium-aluminum-arsenide wave at 660 nm (red laser), 0.028 cm2, 0.1 W, 3.57 W/cm2 for 90 s per point, 9 J per point, 321 J/cm2, and a total energy of 27 J. PBMT was applied weekly after surgery at 808 nm wavelength (other parameters being equal) for wound healing and pain relief. Both patients were followed-up for two years without any report of recurrence. Thus, aPDT and PBMT can be considered non-invasive adjuvant therapies for MRONJ without any adverse effects.

Objetivo: Este trabalho versa sobre as características clínicas de um caso de amelogênese imperfeita (AI) do tipo IIA (hipomaturado com pigmentação difusa), apresentando formas de tratamento e como essa condição afeta a qualidade de vida do paciente. Materiais e métodos: Um paciente com 7 anos de idade, do sexo masculino, apresentando dentição decídua e permanente, procurou atendimento odontológico em razão das seguintes alterações dentárias: coloração dental amarelo-acastanhado, superfície rugosa, presença de cálculos dentais nos incisivos inferiores, mordida topo a topo e sensibilidade dentinária exacerbada. No exame radiográfico foi possível observar que o volume dos tecidos dentários estava normal, mas existia falta de contraste entre esmalte e dentina em todos os dentes, características compatíveis com o diagnóstico clínico de AI-IIA. Como tratamento, foram realizadas restaurações com cimento de ionômero de vidro, aplicação de flúor verniz e bochechos com fluoreto de sódio 0,05% diariamente. Resultados: O tratamento executado foi considerado um sucesso, uma vez que as queixas do paciente foram solucionadas por meio de um tratamento odontológico adequado, restabelecendo a função e a estética da criança de acordo com sua necessidade. Conclusões: O diagnóstico precoce da AI é de suma importância para um tratamento mais conservador e com enfoque na prevenção dos efeitos dessa patologia. Do ponto de vista odontológico, o tratamento da AI tem como principal objetivo devolver a saúde bucal do paciente e, consequentemente, reintegrá-lo ao convívio social com maior qualidade de vida.

Objective: This study aimed to systematically review the literature about sealants modified with materials to promote antimicrobial activity and answer the question “What is the effect of incorporating materials that promote antimicrobial activity to pit and fissure sealants?” Materials and methods: Data were collected from questions about the material incorporated, its concentration, purpose of incorporation, analyses, and conclusions obtained. The Cochrane Library, LILLACS, ScienceDirect, and PubMed databases were searched with the terms “SEALANT”, “ANTIMICROBIAL”, and “ANTIBACTERIAL”. The selection of studies was performed in two stages. Inclusion criteria were applied via the evaluation of titles and abstracts, and exclusion criteria, via the complete reading of the studies. The adapted Joanna Briggs Institute (JBI) tool was used to analyze bias risk. Results: Due to the heterogeneity of the data found, it was impossible to perform a meta-analysis. We obtained 1389 references, including 11 of them in this review. Analysis of the studies found that modified sealants may show antimicrobial activity and alter their other properties. After applying the JBI tool, all studies showed low bias risk. Conclusion: Modified pit and fissure sealants show antimicrobial activity and altered physicochemical and mechanical properties.
目的:本研究旨在系统地回顾有关用增强抗菌活性的材料修饰的密封剂的文献，并回答“加入增强抗菌活性的材料对坑状和裂隙状密封剂有什么影响?”材料和方法:收集资料的问题包括纳入的材料、其浓度、纳入的目的、分析和得出的结论。检索Cochrane Library、LILLACS、ScienceDirect和PubMed数据库，检索词为“SEALANT”、“ANTIMICROBIAL”和“ANTIMICROBIAL”。研究的选择分两个阶段进行。纳入标准通过对标题和摘要的评价来应用，排除标准通过对研究的完整阅读来应用。采用乔安娜布里格斯研究所(Joanna Briggs Institute, JBI)的改进工具分析偏倚风险。结果:由于所发现数据的异质性，无法进行meta分析。我们获得文献1389篇，其中11篇在本综述中。研究分析发现，改性密封剂可能显示出抗菌活性，并改变其其他特性。应用JBI工具后，所有研究偏倚风险均较低。结论:改良的窝沟密封剂具有抗菌活性，并改变了其物理化学和力学性能。

Objective: The aim of this study is to determine the prevalence of idiopathic osteosclerosis (IO) in the mandible in an Iranian subpopulation using cone beam computed tomography (CBCT). Methods: This cross-sectional study was performed on all CBCT images obtained in 2010-2014 from the archive of Oral and Maxillofacial Radiology Department at Isfahan Dental School. Images were evaluated by two observers in identical room and monitoring conditions. IO was defined as homogenous radiopacities with no particular etiology, ranging from 2 mm to 2 cm in size. Demographic information of all patients, as well as the lesion’s number, location, border, shape, and association with adjacent teeth were recorded. Results: From 377 CBCT images, 43 images (11.4%) had at least one IO lesion. Two separate IO lesions were detected in six patients; therefore, 49 IO lesions were found in total. No gender differences were observed in IO prevalence (P = 0.806). Although most common in patients who were in their 30s, IO prevalence was not statistically different among age groups (P = 0.369). IO was most frequent in the molar region, with 63.2% of lesions. Conclusion: IO prevalence was 11.4% in the studied population and was not statistically different between age groups or sexes. Most lesions were found in the mandibular molar region.

Objectives: To compare the accuracy of two methods for the manufacturing of physical models: I) intraoral scanning and resin-printed models; and II) addition silicone impression and gypsum model. Materials and methods: A dental manikin was used as the master model and compared with five gypsum models (g1) and five resin printed models (g2) by analyzing linear measurements at four sites (M1, M2, M3, and M4) using an image measuring instrument. The mean values of the experimental models were compared to those of the master model using one-sample t-test. The samples of each group at the same site were compared with an independent t-test. For all tests, a significance level of 5% (0.05) was considered. Results: The confidence intervals from M1, M2, and M4 sites for both gypsum and resin models presented statistically lower linear distance when compared to the reference values. At m3, the mean value for the gypsum models was not statistically different from the reference mean value (p > 0.05); however, resin-printed models presented a statistically different mean value (p < 0.05), as well as lower values of linear distance. Conclusions: When compared to gypsum models, resin- printed models differed greatly from the master model, indicating the need for standardizing the printing protocol, for its variables may influence printed models accuracy.
