Abstract　： [ABSTRACT] This study was conducted to investigate the influence of lifestyle on sleep bruxism in Japanese elementary school children. A total of 1956 children (973 males, 983 females; mean age, 8.8 +- 1.8 years) and parents living in metropolitan Tokyo participated. Parents answered questionnaires on sleep habits, sleep problems, and lifestyle. Participants were classified as severe bruxism group (s-Bx) and non-severe bruxism group (ns-Bx) according to the frequency of sleep bruxism. The six grades were summarized into three categories: 1st/2nd grades (grades 1/2), 3rd/4th grades (grades 3/4), and 5th/6th grades (grades 5/6). The results suggest that the incidence of sleep bruxism in Japanese children living in Tokyo is strongly related to the disturbance of sleep habits and psychological stress, which can be caused by an owl-type lifestyle in children and parents. [INTRODUCTION] Sleep bruxism is considered as an oral parafunctional habits, and reported in 11 - 20% of children younger than 12 years.
