Impact of Oral Health Status on Perceived Dental Problems Among Japan Maritime Self-Defense Force Personnel.

Introduction: Dental problems may have a great impact on military mission effectiveness, as such, evidence-based dental classification guidelines are required for minimizing the occurrence of dental problems. The aim of this study is to elucidate the independent contribution of each oral disease to the perception of dental problems among Japan Maritime Self-Defense Force (JMSDF) personnel in order to make the dental classification guidelines more precise for the prediction of future dental problems.

Materials And Methods: Japan Maritime Self-Defense Force personnel who were examined during the annual dental checkup in 2013 answered questions about the experience of dental problems within the last 12 months in 2014.

Distribution of muscle fibre types in the thoracic and lumbar epaxial muscles of Japanese macaques (Macaca fuscata).

Histochemical properties are investigated in the thoracic and lumbar epaxial muscles of Japanese macaques, Macaca fuscata. Whole transverse sections of the muscles were removed at the different levels of the thoracic and lumbar vertebrae and muscle fibre types were classified into type I and type II fibres on the basis of their histochemical profiles. In the lumbar region the iliocostalis and longissimus muscles have many type II fibres.
