The bifid mandibular condyle is an exceedingly rare anomaly, frequently diagnosed as an incidental finding in a panoramic radiograph. Its etiology and pathogenesis are unknown, though the most acceptable theory suggests that trauma is at the origin of the condition. This article reports a new case of bilateral bifid condyle in a 21-year-old female with history of trauma in childhood.

El proceso condilar bífido es una anomalía muy rara. Se diagnostica como un hallazgo accidental en una radiografía panorámica. Su etiología y patogenia son desconocidas, aunque la teoría más aceptada sugiere que el trauma está en el origen de esta condición. Este artículo presenta un nuevo caso de proceso condilar bífido bilateral en una mujer de 21 años de edad con antecedentes de trauma en la infancia.

O objetivo do presente estudo foi avaliar a necessidade de distinção entre pacientes brancos e negros quando da estimativa da largura mesiodistal combinada da coroa de caninos e pré-molares em Recife. Uma amostra de 120 modelos de gesso (60 de negros e 60 de brancos) foi selecionada dos arquivos de clínicas do Recife. As larguras mesiodistais das coroas dos caninos e pré-molares superiores e inferiores e dos incisivos inferiores foram medidas nesses modelos, utilizando-se um paquímetro com precisão de 0,02mm. As larguras mesiodistais combinadas desses dentes nos pacientes negros foram comparadas com aquelas encontradas nos pacientes brancos; e comparadas com aquelas estimadas por equações de regressão elaboradas com base na amostra de pacientes brancos e com base em uma ampla amostra de recifenses. O estudo verificou não apenas a não diferença significativa entre brancos e negros na largura mesiodistal combinada de nenhum dos três grupos de dentes analisados, como também verificou que equações elaboradas com base na amostra de indivíduos brancos ou na amostra de recifenses foram estatisticamente precisas em estimar a largura de caninos e pré-molares dos negros. O estudo concluiu que não há necessidade de tabelas ou equações específicas segundo a raça do paciente para a análise de dentição mista em Recife.

The aim of the present study was to evaluate the need to distinguish between white and black patients when predicting the combined mesiodistal crown width of canines and premolars in Recife. A sample of 120 dental casts (60 from black and 60 from white patients) was selected from the archives of dental clinics in Recife. The mesiodistal crown width of the maxillary and mandibular canines and premolars and of the mandibular incisors was measured in these casts using a caliper with an accuracy of 0.02mm. The combined mesiodistal crown width of these teeth in the black patients was compared with that found in the white patients, and also with the estimated values obtained by regression equations based on the sample of white patients and on a large sample of a population from the same city. The study demonstrated that there were no significant differences between whites and blacks in the combined mesiodistal crown width of any of the three analyzed teeth groups and also revealed that such equations were statistically accurate in estimating the mesiodistal crown width of canines and premolars in blacks. It was concluded that there is no need for specific tables or equations regarding the patient's race in the analysis of mixed dentition in Recife.

The present study aimed to survey students' opinions on the use of computer-aided classes for teaching anatomy. Thus, a questionnaire with closed questions was administered at the end of the Anatomy course to undergraduate dental students, which produced a total of 76 valid questionnaires. While studying this subject, the students accessed a room equipped with computers containing previously installed Anatomy programs. The analysis of the questionnaires showed that for most students the computer room considerably facilitates the study of Anatomy and potentially increases the comprehension of the lessons' goals, as well as being an extremely important aid in studying anatomy. However, most students reported that they did not prefer this learning tool to the study of dissected cadavers, and considered that the computer room cannot replace cadavers. The present study concludes that the students interviewed consider the use of computer rooms as an effective adjunct to enhance the learning of anatomical concepts; nevertheless, it is a supplement to, not a surrogate for cadavers

El objetivo de este trabajo fue conocer la opinión de los alumnos sobre la utilización de salas de informática para la enseñanza de la Anatomía. Para ello, fue utilizado un cuestionario con preguntas objetivas, que fue presentado a los alumnos del curso de Odontología, al final de la disciplina de Anatomía, resultando 76 cuestionarios válidos. Estos alumnos tuvieron, en la disciplina, acceso a una sala equipada con computadores con programas de Anatomía, previamente instalados (sala de informática). El análisis de los cuestionarios mostró que, para la mayoría de los alumnos participantes, el uso de la sala de informática facilita mucho el estudio de la Anatomía, aumenta ostensiblemente el logro de los objetivos de la clase y es muy útil para el estudio de la Anatomía. Sin embargo, la mayoría de los alumnos relató no preferir estudiar utilizando esta herramienta de enseñanza y consideró que la sala de informática no puede sustituir las piezas cadavéricas. El presente estudio concluyó que los alumnos investigados consideran la utilización de salas de informática como un elemento que mejora la enseñanza de la Anatomía, sin embargo, no sustituyen a las piezas cadavéricas
