Outline of Final Research Achievements	We studied whether the treatment to correct the habit of unconsciously upper and lower teeth observed during the day (tooth contacting habit :TCH) will reduce the chewing muscle activity at sleep (bruxism). The frequencies of TCH were statistically significantly reduced after treatment compared with treatment before correction. However, the number of bruxism only showed a slight decrease from before treatment to after treatment. It was shown that there is a possibility that TCH and the bruxism are not related.
