RESUMO Objetivos: identificar as evidências disponíveis na literatura sobre o conhecimento dos cirurgiõesdentistas quanto aos fatores de risco e diagnóstico precoce do câncer de boca e orofaringe. Métodos: trata-se de uma revisão integrativa da literatura. Foram realizadas buscas mediante os descritores e operadores booleanos na base de dados PubMed e LILACS, com uso de literatura cinza, nos idiomas inglês, espanhol e portugês. Resultados: dos 79 artigos do PubMed e 152 do LILACS, 24 foram selecionados. Destes, oito mostraram bom conhecimento dos dentistas, enquanto a maioria mostrou baixo ou pouco conhecimento sobre fatores de risco e diagnóstico precoce em dentistas. Todos os estudos, no entanto, destacam a necessidade de educação continuada para melhorar e manter o conhecimento sobre fatores de risco e diagnóstico precoce. Conclusões: grande parte dos cirurgiões-dentistas apresenta um conhecimento insuficiente sobre câncer de boca/orofaringe. É sugerida a educação continuada, visando melhorar o conhecimento e o diagnóstico precoce.

ABSTRACT Objectives: to identify the evidence available in the literature on the knowledge of dentists regarding risk factors and early diagnosis of oral and oropharyngeal cancer. Methods: it is an integrative review of the literature. Boolean descriptors and operators were searched in the PubMed and LILACS databases, using gray literature, in English, Spanish and Portuguese. Results: of the 79 PubMed and 152 LILACS articles, 24 were selected. Of these, eight showed good knowledge of dentists, while most showed low or little knowledge of risk factors and early diagnosis in dentists. All studies, however, highlight the need for continuing education to improve and maintain knowledge about risk factors and early diagnosis. Conclusions: most dental surgeons have insufficient knowledge of oral/oropharyngeal cancer. Continued education is suggested, aiming at improving knowledge and early diagnosis.

Abstract Objective: To investigate the involvement of young Brazilian students about five behaviors: tobacco use, alcohol consumption, sexual intercourse, knowledge about HPV, and knowledge about oral and oropharyngeal cancer. Material and Methods: Through a cross-section design, we explored some factors that might be associated with boys and girls. Statistical Regression methods were applied to identify differences, considering the estimation of the Odds Ratio. Results: Half of the sample had already consumed alcohol and at least 1 in 10 individuals had already tried smoking. One-third of adolescents have had sexual intercourse. Three factors related to boys were associated in the multiple regression analysis: have heard about HPV, have not heard about oral cancer, and think that HPV can cause oropharyngeal cancer. In conclusion, it seems that boys and girls were equally exposed to smoking-alcohol-sex; however, some differences were verified concerning the knowledge about HPV and oral / oropharyngeal cancer. Conclusion: Keep monitoring adolescents should be a priority to our study area, considering that those youngers had already being exposed to the risk factors for cancer.

ABSTRACT OBJECTIVE To evaluate the effect of the time and the sex of victims and perpetrators on the rates of family and community physical violence in a Brazilian municipality over seven years (2008–2014). METHODS We made a census analysis from non-fatal victims attended in the Forensic Institute of the Scientific Civil Police. The monthly and annual violence rates were calculated based on the population size of the municipality. Time series was evaluated by negative binomial regression models, based on the number of cases with population offset and considering the effect of the sex of victims and perpetrators. RESULTS A total of 3,324 cases of family and 4,634 cases of community violence were analyzed. There was a significant increase in family violence rates for female victims and male perpetrators. Family violence rates were always higher for female victims than for male and it was always lower for female perpetrators than for male (p < 0.001). There was a lower risk of community violence for male victims after 2013 and a decrease of aggression perpetrated by men over time. Men and women were similarly affected by community violence; however, the perpetrators were more frequently men. CONCLUSIONS The results indicate a trend of increasing female victims in the family violence, mainly perpetrated by men. The reduction in community violence rates could be the result of policies to reduce crime.

RESUMO O objetivo deste estudo foi determinar as circunstâncias das agressões e os padrões dos traumas maxilofaciais entre vítimas de violência interpessoal. Tratou-se de um estudo transversal e exploratório feito a partir da análise de 7.132 registros médico-legais e sociais de vítimas de violência interpessoal atendidas em um Centro de Medicina Legal e Odontologia Forense. Foi feita estatística descritiva e multivariada, usando Análise de Correspondência Múltipla. Três grupos com perfis distintos de vitimização foram identificados. O primeiro grupo foi formado majoritariamente por homens, de diferentes faixas etárias, vítimas de violência comunitária, resultando em fratura de ossos faciais ou fratura dentoalveolar. O segundo grupo foi composto essencialmente por adolescentes (10-19 anos), de ambos os sexos, vítimas de violência interpessoal e que não apresentaram um padrão específico de trauma. O terceiro grupo reuniu mulheres, adultas (≥ 20 anos), vítimas de violência doméstica, resultando em lesão de tecidos moles da face ou em outras regiões do corpo. Os resultados sugerem que as características sociodemográficas e circunstanciais são fatores importantes na vitimização por traumatismo maxilofacial e violência interpessoal.

Abstract The aim of this study was to determine the circumstances of aggressions and patterns of maxillofacial injuries among victims of interpersonal violence. This was a cross-sectional and exploratory study conducted from the analysis of 7,132 medical-legal and social records of interpersonal violence victims seen in a Forensic Medicine and Dentistry Center. Descriptive and multivariate statistics were performed using Multiple Correspondence Analysis. Three groups with different victimization profiles were identified. The first group was mainly composed of men of different age groups, victims of community violence that resulted in facial bones or dentoalveolar fracture. The second group was mainly composed of adolescents (10-19 years) of both sexes, victims of interpersonal violence and without specific pattern of injuries. The third group was composed of adult women (≥ 20 years) victims of domestic violence that resulted in injuries of soft tissues of face or other body regions. The results suggest that sociodemographic and circumstantial characteristics are important factors in victimization by maxillofacial injuries and interpersonal violence.

RESUMO: Objetivo: Descrever o perfil da violência contra mulheres em diferentes ciclos de vida, de acordo com as características sociodemográficas das vítimas e dos agressores. Métodos: Estudo transversal e exploratório realizado com base em 1.388 registros de ocorrências, durante período de quatro anos, em uma região metropolitana do Nordeste do Brasil. A variável dependente foi o tipo de agressão sofrido pelas vítimas. As variáveis independentes foram as características sociodemográficas das vítimas e dos agressores. A análise estatística incluiu o teste χ2 (p < 0,05) e a análise de árvore de decisão, por meio do algoritmo Chi-squared Automatic Interaction Detector (CHAID). Resultados: Os casos de agressão física (n = 644) foram os mais comuns, seguidos de ameaça (n = 415) e agressão verbal (n = 285). Os perfis da violência puderam ser explicados pela relação entre vítimas e agressores (p < 0,001) e faixa etária das vítimas (p = 0,026 em Nó 1; p = 0,019 em Nó 3). Conclusão: Foi observado que mulheres em diferentes fases da vida apresentam mais exposição a diferentes tipos de violência.

ABSTRACT: Objective: The aim of this study was to describe the profile of violence against women in different life cycles, according to the sociodemographic characteristics of the victims and offenders. Methods: A cross-sectional and exploratory study was performed based on 1,388 police reports during a four-year period, in a metropolitan area of Northeast Brazil. The dependent variable was the type of aggression suffered by the victims. The independent variables were sociodemographic characteristics of the victims and offenders. Statistical analysis included the χ2 test (p < 0.05) and the decision tree analysis, through the Chi-squared Automatic Interaction Detector (CHAID) algorithm. Results: Cases of physical abuse (n = 644) were the most common, followed by threat (n = 415) and verbal aggression (n = 285). The violence profiles could be explained by the relationship between victims and offenders (p < 0.001) and age of the victims (p = 0.026 in Node 1; p = 0.019 in Node 3). Conclusion: It was observed that women in different stages of life are more exposed to different types of violence.

RESUMO Objetivo: Analisar a ocorrência de acidente de transporte terrestre entre duas modalidades de motociclistas que realizam o transporte de passageiros em um município do Nordeste Brasileiro. Métodos: Nesta cidade existem dois grupos de motociclistas regulamentados, um destes trabalhava para prefeitura e outro para uma empresa privada. Foi realizada uma entrevista por meio de um questionário para uma amostra probabilística de 210 sujeitos (n = 125 da prefeitura, n = 85 empresa). Resultados: Um elevado número de motociclistas entre as duas modalidades (78,6%) sofreram acidente de trânsito nos últimos 12 meses à realização do inquérito, sendo a colisão coo o automóvel o tipo mais frequente (43,6%). Entretanto, a modalidade de motociclistas da prefeitura estiveram mais associados com a presença de acidentes (p < 0,05), principalmente pelo fato de estarem trabalhando a mais tempo (p < 0,001). A ocorrência de injúrias corporais foi alta (63,6%) em ambas as modalidades. Injúrias faciais foram menos frequentes para as duas modalidades analisadas, principalmente devido ao uso do equipamento de proteção (98,2%). Conclusão: O alto número de motociclistas acidentados entre as duas modalidades de transporte de passageiros, mostra a falta de segurança deste tipo de transporte. Considerando que estes motociclistas realizam o transporte público de passageiros é necessário melhorias na regulamentação e na prevenção de acidentes.

ABSTRACT Objective: The aim of the present cross-sectional study was to analyze the occurrence of ground transportation accidents involving two categories of motorcyclists who transport passengers in a city located in northeastern Brazil: those who work for city hall and those who work for a private transportation firm. Methods: Interviews were held with the aid of a questionnaire administered to a probabilistic sample of 210 individuals (125 from city hall and 85 from the private firm). Results: A high number of motorcyclists in both categories combined (78.6%) suffered traffic accidents in the 12 months prior to the inquiry. Collisions with automobiles constituted the most frequent type of accident (43.6%). Accidents were more associated with motorcyclists working for city hall (p < 0.05), due mainly to the fact that these individuals had been employed for a longer period of time (p < 0.001). The occurrence of bodily injuries was high in both categories (63.6%). Facial injuries were the least frequent in both categories due mainly to the use of protection equipment (98.2%). Conclusion: The occurrence of traffic accidents was high in the two motorcycle passenger transportation categories analyzed, demonstrating that motorcycles are used to transport passengers in a risky manner.

Resumo Introdução: Nos países em desenvolvimento, os acidentes de transporte terrestre (ATTs) são uma das principais causas de trauma facial, superando os casos de violência urbana, especialmente aqueles envolvendo automóveis e motocicletas. Objetivo: O objetivo deste estudo transversal censitário foi determinar a ocorrência de traumas faciais com etiologia de acidente de transporte terrestre (ATT): automóveis, motocicletas ou atropelamentos, em uma cidade do Nordeste do Brasil. Método: Foram analisados os dados de morbidade em laudos de um serviço forense de vítimas que procuraram o serviço de janeiro a dezembro de 2010. Resultados: Ao todo, foram avaliados 2.379 laudos; 673 eram referentes a ATTs, e 103 apresentaram traumas faciais. A coleta de dados foi realizada por três pesquisadores previamente treinados e calibrados, sendo elaborado um formulário específico para coleta das informações contidas nos laudos. Destes, 15,3% (n = 103) sofreram trauma facial. A faixa etária predominante para os eventos de trauma facial foi de 20-29 anos (48,3%), acometendo mais homens do que mulheres (2,81:1). A motocicleta foi o principal tipo de veículo com envolvimento de vítimas (66,3%). Conclusões: A ocorrência de traumas faciais em vítimas de acidente de transporte terrestreten de a afetar, em maior proporção, indivíduos homens e jovens, com maior prevalência para os acidentes envolvendo motocicletas.

ABSTRACT INTRODUCTION: In developing countries, terrestrial transport accidents - TTA, especially those involving automobiles and motorcycles - are a major cause of facial trauma, surpassing urban violence. OBJECTIVE: This cross-sectional census study attempted to determine facial trauma occurrence with terrestrial transport accidents etiology, involving cars, motorcycles, or accidents with pedestrians in the northeastern region of Brazil, and examine victims' socio-demographic characteristics. METHODS: Morbidity data from forensic service reports of victims who sought care from January to December 2012 were analyzed. RESULTS: Altogether, 2379 reports were evaluated, of which 673 were related to terrestrial transport accidents and 103 involved facial trauma. Three previously trained and calibrated researchers collected data using a specific form. Facial trauma occurrence rate was 15.3% (n = 103). The most affected age group was 20-29 years (48.3%), and more men than women were affected (2.81:1). Motorcycles were involved in the majority of accidents resulting in facial trauma (66.3%). CONCLUSION: The occurrence of facial trauma in terrestrial transport accident victims tends to affect a greater proportion of young and male subjects, and the most prevalent accidents involve motorcycles.

BACKGROUND: Patients with diabetes mellitus have been associated with a number of changes in the oral cavity, such as gingivitis, periodontitis, mucosal diseases, salivary dysfunction, altered taste, and burning mouth. OBJECTIVES: To determine the prevalence of oral mucosal lesions in patients with diabetes mellitus. METHODS: A cross-sectional observational study between August and October 2012 with a convenience sampling was performed for 51 patients with diabetes mellitus (type 1 and type 2). The study consisted of two phases: 1) a questionnaire application; 2) intraoral clinical examination. For the analysis of data, we used descriptive statistics, Fisher's exact test in bivariate analysis (significance level of 0.05), and Poisson Regression. RESULTS: The prevalence of oral lesions was 78.4%. Traumatic ulcers (16.4%) and actinic cheilitis (12.7%) were the most prevalent lesions. The lips (35.3%) and tongue (23.5%) were the most common location. The bivariate analysis showed an association with the type of diabetes, and two variables (age and comorbidity) were quite close to the significance level. In the Poisson Regression analysis, only diabetes type 2 remained significant after adjusting the model. CONCLUSIONS: The results of this study show a high prevalence of oral mucosal lesions in diabetic patients. The oral mucosal lesions are mostly associated with diabetes type 2.

JUSTIFICATIVA E OBJETIVOS: A dor é um sintoma clínico característico em estágios iniciais do tratamento ortodôntico. O objetivo deste estudo foi rever na literatura o uso da terapia a laser de baixa intensidade na redução da dor durante o tratamento ortodôntico. CONTEÚDO: Uma busca de títulos, resumos e artigos foram realizadas nas bases de dados Pubmed/Medline, Cochrane Library, LILACS e Scielo. Três pesquisadores realizaram de forma independente uma busca utilizando critérios de inclusão e exclusão definidos. Foram incluídos oito ensaios clínicos, sendo que seis deles verificaram redução significativa da dor após uso do laser terapêutico. CONCLUSÃO: Existe evidência científica de que o uso do laser de baixa intensidade diminui a sintomatologia dolorosa após colocação de elásticos ortodônticos e após realização de ajustes ortodônticos durante a movimentação dentária. O seu uso por profissionais da área é uma alternativa viável por apresentar menos efeitos colaterais em relação a analgésicos anti-inflamatórios, sendo bem indicado a pacientes alérgicos, crianças e pacientes com comprometimento sistêmico. No entanto, há a necessidade de investigações científicas adicionais que utilizem protocolos bem definidos.

BACKGROUND AND OBJECTIVES: Pain is a typical symptom during early orthodontic treatment. This study aimed at reviewing the literature on the use of low intensity laser to relieve pain during orthodontic treatment. CONTENTS: Titles, summaries and articles were searched in the following databases: Pubmed/Medline, Cochrane Library, LILACS and Scielo. Three researchers have independently searched using defined inclusion and exclusion criteria. Eight clinical trials were included and six have observed significant pain relief after therapeutic laser. CONCLUSION: There are scientific evidences that low intensity laser decreases pain symptoms during dental movements after the placement of orthodontic elastics and after orthodontic adjustments. Its use by dentists is a feasible alternative for inducing less adverse effects as compared to anti-inflammatory analgesics, being indicated for allergic patients, children and patients with systemic impairment. However, there is the need for further scientific investigations using well-defined protocols.
