Dental practice and musculoskeletal disorders association: a look at the evidence.

Disorders localized to the musculoskeletal system are a common problem among dental personnel. This study has the aim of surveying epidemiological studies reporting positive associations between dental practice and musculoskeletal disorders (MSKDs). The focus was to evaluate the size of reported risk increase and the extent to what alternative causal explanations were considered. Reports with significant links (p value <.05) were systematically selected from 2 electronic databases. Twenty-five studies were identified. Risk measures were reported in 8 studies, and all of them presented weak associations. The impact of at least 1 competing explanations was analyzed in 32% of studies, but adjustment was considered not adequate in half of them. The evidence on dentistry as a profession with potential risk for development of MSKDs remains questionable. Further research is needed to more carefully elucidate the risk and the impact of MSKDs in this particular occupational group.

Sialolitíase em ducto de glândula submandibular: relato de dois casos clínicos / Sialolithiasis in submandibular gland duct: two cases report

Sialolitos são estruturas calcificadas que se desenvolvem no interior dos ductos das glândulas salivares e estão relacionados principalmente com a glândula submandibular. Neste trabalho são apresentados dois casos clínicos de pacientes portadores de sialolitíase em ducto de glândula submandibular. Os pacientes eram um do sexo feminino e o outro do sexo masculino, com idade de 59 e 71 anos respectivamente. Os dois casos foram tratados cirurgicamente, embora os sialolitos apresentassem tamanho e localização intraductal diferentes. São enfatizados, para o diagnóstico, suas características clínicas e exames complementares. Na discussão procurou-se abordar a etiologia da lesão e fatores que devem ser considerados para o tratamento adequado e um melhor prognóstico
