Bruxism に関する研究とくに Grinding の発現頻度について

Prevalence of grinding habit was studied on 539 students of a womens college, aged 18 to 21 years, and 85 dental students, aged 23 to 27 years. On the womens college students, examination of gingiva, eye, ear, nose and throat were also performed to know the relation with grinding habit. The results of this study were as follows: 54 womens college students (9.85%) and 19 dental students (22.35%) had grinding habit, and 71 womens college students (13.20%) and 7 dental students (8.20%) were suspected to have the habit. Any changes of gingiva, eye, ear, nose and throat were not significantly related to the existence of grinding habit.
