Abstract This study investigated factors that affect the use of complete conventional mandibular dentures (CCMD) by patients of the Brazilian Public Health Service. For this, two hundred and thirty one subjects who received CCMD in the Primary Health Care of the Public Health Service in Belo Horizonte – Brazil were evaluated and divided in Group 1 – irregular/non-wear; Group 2 – regular wear. Multivariate logistic regression analysis was used to create predictive models for CCMD non-wear and included socio-demographic and biological variables, technical quality of CCMD, and user satisfaction. The prevalence of CCMD non-wear was 41.10%. The mean score of CCMD quality was 54.97 (0–100). Not wearing the CCMD was significantly associated with user satisfaction and technical quality (p < 0.05). The lack of retention of the CCMD was the most important factor in the evaluation of satisfaction and quality. The final predictive model (specificity = 92.65%; AROC = 0.8759) for not wearing the CCMD retained the variables CCMD stability (OR = 0.888; 95%CI = 0.827–0.954), freeway space (OR = 0.916; 95%CI = 0.860–0.976), satisfaction with speech (OR = 0.694; 95%CI = 0.612–0.786), and irregular CCMD edges (OR = 3.185; 95%CI = 1.478–6.864). Socio-demographic and biological variables were not associated with patients not wearing the CCMD, whereas technical quality and user satisfaction were strongly associated.

Os traumas maxilofaciais decorrentes da violência contra crianças e adolescentes impactam suas vidas, física e psiquicamente, pelas deformidades que podem provocar e pela exposição da lesão na face das vítimas. O objetivo deste trabalho é identificar a prevalência dos traumas maxilofaciais em crianças e adolescentes decorrentes da violência urbana em Belo Horizonte- Brasil. O estudo foi conduzido no Hospital Municipal Odilon Behrens, único hospital municipal de referência nesse tipo de atendimento em Belo Horizonte. Coletaram-se os registros de vítimas atendidas de janeiro a dezembro de 2007. O principal evento de violência sofrido entre crianças e adolescentes foi agressão física, 44,2% e 64,7%, respectivamente. Entre as crianças, o tipo de trauma mais comum foi o trauma dentoalveolar (53,8%), e entre os adolescentes, trauma de tecidos moles (47,5%). O maior número de ocorrências se deu no período noturno: crianças (84,6%) e adolescentes (74,8%). O gênero mais vitimado foi o masculino, crianças (63,5%) e adolescentes (68,3%). Estratégias apropriadas para identificação do evento de violência e do agressor são necessários para que melhor sejam planejados mecanismos de proteção da criança e do adolescente, uma vez que a violência sofrida por crianças e adolescentes no Brasil, considerando a complexidade dessa fase da vida, assume um quadro sombrio, desconstruindo o desenvolvimento, a sociabilidade e comprometendo a visão das vítimas sobre si mesmas e sobre o mundo que as cercam.

The maxillofacial traumas resulting from violence against children and adolescents have physical and psychical impact on their lives, because of the deformities and the injuries on their faces. This study aims to identify the prevalence of maxillofacial traumas in children and adolescents caused by urban violence in Belo Horizonte, Brazil. The study was conducted at Hospital Municipal Odilon Behrens, the primary reference hospital in this type of care in Belo Horizonte. We collected records of victims attended between January and December 2007. Among children and adolescents, the most recurring violence event was physical aggression, 44,2% and 64.7% respectively. Among children, the most common type was the dental-alveolar trauma (53.8%), while among adolescents, soft tissues trauma (47.5%). The highest number of occurrences was at night, for both children (84.6%) and adolescents (74.8%). The most victimized gender was masculine, children (63.5%), and adolescents (68.3%). Appropriate strategies to indentify violent events, as well as the aggressor himself, are necessary for planning better protection mechanisms for children and adolescents, since the violence suffered by this group in Brazil, considering the complexity of this stage of life, takes a gloomy picture, deconstructing their development, sociability, and undermining the victims' perspective about themselves and the world around them.
