Aim:This study aimed to evaluate the scientific evidence regarding the risk factors for maxillofacial injuries among victims of traffic accidents. Method:A systematic review of articles published until February 2017 was carried out in the following databases: PubMed, Web of Science, Scopus, and Cochrane Library. Studies were selected by two independent reviewers ( = 0.841). The risk of bias in the selected studies was assessed using an adapted version of the Newcastle-Ottawa Scale for observational studies. Results: A total of 2703 records were found, of which only three articles fulfilled the inclusion criteria and were analyzed, including 422 244 patients. The male/female ratio ranged from 3.4: 1 to 6: 1. All eligible studies performed the multivariate statistical analysis. Eleven risk factors for maxillofacial traumas were identified: victim's gender (P < 0.05), age group (P < 0.05), residence region (P < 0.05), impact characteristics (P < 0.05), increased net change in velocity due to collision (P < 0.05), increase in occupant's height (P < 0.05), nonuse of protective equipment (P < 0.05), type of accident (P < 0.05), time of occurrence (P < 0.05), lesion severity (P < 0.05), and occurrence of concomitant lesions (P < 0.05). Conclusion:The results suggest that sociodemographic characteristics, as well as those related to the collision patterns and circumstances of traffic accidents, may influence the occurrence of maxillofacial injuries. However, the results should be interpreted with caution due to the high heterogeneity among studies.

Introdução: A terapia fotodinâmica representa uma abordagem alternativa para a desinfecção do tecido cariado e tem apresentando resultados promissores no que diz respeito ao seu efeito deletério sobre os microrganismos envolvidos na progressão da cárie dentária. Objetivo: Investigar a produção científica brasileira sobre Terapia Fotodinâmica no manejo da Cárie dentária. Material e método: Tratou-se de uma pesquisa transversal, com abordagem quantitativa, a partir de dados secundários. Realizou-se uma análise bibliométrica dos resumos apresentados nas últimas dez Reuniões da Sociedade Brasileira de Pesquisa Odontológica. A pesquisa dos trabalhos procedeu-se através da seguinte estratégia: localização do fragmento “terapia fotodinâmica” e/ou “fotodinâmica” entre os resumos publicados nos anais do evento (1ª fase), em seguida foi realizada a busca pelo fragmento “cárie” e/ou “cardiologia” nos resumos selecionados na 1ª fase. Resultados: Foram selecionados 21 resumos, desses, 15 (71,43%) foram realizadas em universidades públicas, 13 (61,91%) receberam auxílio financeiro, 11 (52,38%) foram desenvolvidas na região Sudeste do Brasil, 9 (42,86%) eram do tipo in vitro, 6 (28,58%) utilizaram apenas o azul de toluidina como fotossensibilizante e 5 (23,81%) utilizaram apenas o LED vermelho como fonte de luz. Conclusão: Apesar dos resultados promissores da Terapia Fotodinâmica como terapia adjunta ao manejo da cárie, observou-se que poucas pesquisas abordando esse procedimento foram desenvolvidas nos últimos dez anos no Brasil.Descritores: Fotoquimioterapia; Cárie Dentária; Coleta de Dados.ReferênciasBradshaw DJ, lynch RJ.

ResumoIntrodução: A odontometria constitui uma etapa fundamental para o sucesso do tratamento endodôntico, atualmente existem diversos métodos para a obtenção dessa medida. Objetivo: Realizar uma comparação entre o comprimento real do dente mensurado pelas técnicas de Ingle e eletrônica, utilizando os localizadores apicais eletrônicos Root ZX e Propex. Material e método: Foram selecionados 24 pacientes para participar do estudo, obtendo-se um grupo de vinte e quatro dentes unirradiculares, com rizogênese completa e diagnóstico de necrose pulpar, para realização das mensurações. Após o isolamento, acesso e neutralização do conteúdo séptico do canal radicular, todos os dentes foram submetidos às três técnicas de odontometria, obtendo-se assim o comprimento real do dente. Os dados foram submetidos a uma análise estatística descritiva. Após verificação da normalidade dos dados mediante emprego do teste de Shapiro-Wilk, realizou-se o teste ANOVA o qual demonstrou efeito significativo do tipo de método utilizado para obter os valores do comprimento real do dente. Resultados: A comparação par a par com ajuste de Bonferroni revelou que a média dos valores do comprimento real do dente obtidos por meio da técnica radiográfica de Ingle e do localizador Root ZX foram diferentes de maneira significativa da média dos valores obtidos usando o localizador Propex. Conclusão: Com base nos dados apresentados, conclui-se que o localizador apical Propex apresentou resultados diferentes dos obtidos pela técnica de Ingle e pelo localizador Root ZX.

Abstract Introduction: Odontometry is a fundamental step for successful endodontic treatment, there are currently several methods to obtain this measure. Objective: To perform a comparison between the real length of the tooth measured by the Ingle and electronic techniques, using Root ZX and Propex electronic apical locators. Material and method: Twenty-four patients were selected to participate in the study, obtaining a group of twenty-four unirradicular teeth, with complete rhizogenesis and diagnosis of pulp necrosis to perform the measurements. After the isolation, access and neutralization of the septic contents of the root canal, all teeth were submitted to the three odontometry techniques, thus obtaining the real length of the tooth. The data were submitted to a descriptive statistical analysis. After checking the normality of the data using the Shapiro-Wilk test, the ANOVA test was performed, which demonstrated a significant effect of the type of method used to obtain the actual tooth length values. Results: Comparison with Bonferroni adjustment showed that the mean values of real length of the tooth obtained using the radiographic technique of Ingle and the Root ZX locator were significantly different from the mean values obtained using the Propex locator. Conclusion: Based on the data presented, it was concluded that the apical locator Propex presented results different from those obtained by the Ingle technique and by the...
