RESUMEN
OBJECTIVES: To evaluate four different teaching methodologies in the radiographic diagnosis of proximal carious lesions and in the students' perception of these methodologies. METHODS: 71 undergraduate dental students were subdivided into 4 groups according to the teaching methodologies used (traditional, hybrid, e-learning and problem-based learning). All methods were applied by two properly trained researchers. Initially, students completed a pre-methodology test (index test). After applying the teaching methodologies, the students were submitted to a post-methodology test containing periapical radiographs for evaluation of proximal carious lesions. Then, the students answered a questionnaire to verify their perception of the different teaching methodologies. Statistical analysis was done. RESULTS: There were no relationship between the results of pre- and post-methodologies tests, irrespective of the teaching methodology employed (p > 0.05). No differences between the teaching methodologies studied (p > 0.05) were found regarding the amount of correct answers. However, the students who participated in the active (e-learning and problem-based learning) and hybrid teaching methodology reported a positive impact in relation to their diagnostic skills at the questionnaire. CONCLUSIONS: All the tested methodologies had a similar performance; however, the traditional methodology showed less acceptance by the students when analyzed subjectively and comparatively. The results of the present study increase comprehension about teaching methodologies for radiographic diagnosis of proximal carious lesions, and there is a potential to build on the knowledge base and provide practical support for students and educators.

Little research has been performed on tomographic observations of the dental development anomaly known as enamel pearl. This article presents a clinical case report in which enamel pearl was detected through cone beam computed tomography (CBCT). In this study, a patient was referred to undergo a CBCT of the left maxillary molar region, due to the patient's pain symptoms in this region. The CBCT showed the existence of an enamel pearl in tooth 27. A precise diagnosis made it possible for the patient to begin the preventive treatment against periodontal disease in tooth 27.

A Imagem por Ressonância Magnética (IRM) tem sido considerada a modalidade de escolha para o diagnóstico de processos patológicos que acometem a articulação temporomandibular, tecidos moles e outros processos inflamatórios. Devido a sua característica não invasiva e livre de radiação ionizante, novas aplicações para a técnica têm sido propostas e estudadas nas mais diversas áreas da Odontologia, como Endodontia, Dentística, Periodontia e Cirurgia Oral. O objetivo neste trabalho é apresentar uma revisão de literatura acerca da utilização da IRM na Odontologia, destacando as vantagens e limitações da técnica.
Magnetic Resonance Imaging (MRI) has been considered the modality of choice for the diagnosis of pathological processes that affect the temporomandibular joint, soft tissues and other inflammatory processes. Due to its non-invasive and ionizing radiation-free properties, new applications for the technique have been proposed and studied in several areas of Dentistry, such as Endodontics, Dentistry, Periodontics and Oral Surgery. The aim of this work is to present a literature review about the use of MRI in Dentistry, highlighting the advantages and limitations of the technique.

Objetivo: o objetivo desse trabalho foi estudar, in vitro, o nível de escoamento dos cimentos Endofill, AH Plus, MTA Fillapex, Sealer 26 e Pulp Canal Sealer EWT. Métodos: os cimentos foram manipulados de acordo com as recomendações dos fabricantes. A determinação do escoamento foi conseguida em conformidade com a especificação #57 da ADA (American Dental Association). Na comparação entre os grupos, foi realizada a ANOVA (análise de variância) e posterior teste de Tukey, com nível de confiança de 95%. Resultados: os resultados mostraram que o cimento MTA Fillapex apresentou o maior escoamento entre os cimentos estudados e o cimento AH Plus foi o único que apresentou escoamento estatisticamente significativo após 24 e 48 horas. Conclusão: concluiu-se que todos os cimentos avaliados estão em conformidade com a especificação #57 da ADA. No entanto, o cimento MTA Fillapex foi superior aos outros cimentos analisados, no que se refere ao poder de escoamento. O desempenho clínico do cimento obturador está diretamente relacionado à sua capacidade de penetrar nos túbulos dentinários e canais laterais; daí a importância do estudo do escoamento dos cimentos endodônticos.
