The objective of this article was to investigate the perception of esthetic changes in the facial profile of bilateral Class II patients treated with the Modified Thurow Appliance for extraoral treatment. Silhouettes were traced of profiles of patients who initially presented a bilateral Class II molar relationship and who, post-treatment, presented molars in a Class I relationship. Three groups were formed: the first composed of patients with maxillary protrusion (SNA >84°), the second with maxillary retrusion (SNA <80°), and the third with a wellpositioned maxilla (SNA 80-84°). A panel of 200 lay evaluators judged the profile esthetics by a randomized drawing of the silhouettes. The multiple analysis results showed that the profile esthetic scores for the three positions of the maxilla were greatly influenced by significant interactions with the characteristics (like sex and age) of the evaluators: retrusive maxilla (Score *Age Group, p < 0.001), normal maxilla (Score *Sex, p = 0.024; Score *Age Group, p = 0.050) and protrusive maxilla (Score *Age Group, p < 0.001). It was observed that the profile of Class II patients with protrusion, normal relationship and retrusion of the maxilla, improved in their esthetic post-treatment result; however, the evaluators showed greater satisfaction with the groups of protrusion and normal position of the maxilla. The Modified Thurow Appliance provided significant improvements in the esthetics of the profile of patients who presented protrusion and normal position of the maxilla. However, its use was not the best treatment option for patients with maxillary retrusion.

ResumoIntrodução: O prontuário odontológico é indispensável para o planejamento do tratamento por reunir todas as informações pertinentes ao paciente, além de servir como prova legal em processos civis, penais, éticos, administrativos e identificação post-mortem. O correto preenchimento e a guarda de toda documentação odonto-legal devem seguir durante a Graduação e toda a vida profissional. Objetivo: Avaliar a percepção dos discentes de Odontologia sobre o prontuário odontológico, sua composição e importância. Material e método: Trata-se de uma pesquisa descritiva observacional do tipo transversal, na qual foram aplicados questionários aos graduandos do quarto ao décimo semestre do Curso de Odontologia de uma universidade pública do interior do Estado da Bahia, Brasil, a Universidade Estadual do Sudoeste da Bahia (UESB), durante o primeiro período letivo de 2013. Resultado: Dos 142 alunos entrevistados, 105 participaram da pesquisa; a maioria reconhece os documentos que devem compor o prontuário odontológico, 98,10% utilizam o prontuário manuscrito e 33,33% afirmam que o tempo de guarda do prontuário deveria ser ad eternum. Os alunos identificam a importância do prontuário em 93,33% para processos éticos e 97,15% em casos de identificação humana e processos jurídicos. Solicitam a assinatura do paciente para as respostas da anamnese em 85,71% e demonstram desconhecimento da sua importância em outros documentos que compõem o prontuário. Conclusão: Percebe-se que os discentes de Odontologia, em sua maioria, desconhecem o correto tempo de guarda e a necessidade da assinatura nos documentos suplementares.Descritores: Registros odontológicos; estudantes de Odontologia; documentação. AbstractIntroduction: Dental records are essential for treatment planning because they collect all relevant information of the patient, besides serving as legal evidence in civil, criminal, ethical and administrative processes and post-mortem identification. The correct completion and keeping of all forensic dental documentation must continue throughout the undergraduate course and professional life. Objective: To evaluate the perception of dental students, on dental records, their composition and importance. Material and method: It is a descriptive cross-sectional observational survey, in which questionnaires were administered to undergraduate students from the 4th to the 10th semester of a Dentistry Course, at a public University, in the inland of the state of Bahia -Brazil -during the first semester of 2013. Result: Of the 142 interviewed students, 105 participated in the survey; most recognize the documents that should compose the dental records, 98.10% use the manuscript chart, 33.33% state that the keeping time of the records should be ad eternum. The students identify the importance of the records in 93.33% for ethical processes, 97.15% in human identification cases and lawsuits. They request the signature of the patient for the anamnesis' responses in 85.71% and demonstrate ignorance of its importance in other documents that make u...
