Lee, Ho Sun, D.D.S. Advisor : Prof. Lee, Gyeong-Je, D.D.S., M.S.D., Ph.D. Department of Dentistry Graduate School of Chosun University

Purpose : The purpose of this study was to analyze correlation between bruxism and occlusal contacts on balancing side.

Materials and methods : A total of 100 adult males and females aged 26-37 years (39 males and 61 females) were examined. The lateral excusion and balanced occlusal contacts were analyzed to determine the correlation with bruxism. The occlusal contacts were recorded by T-Scan system and articulating paper.

Results : The group function was the highest in the bruxism group (61.5%) and the non-bruxism group (47.5%). In comparison between males and females, group function was 58.9% in males and 37.0% in females. Occlusal contact on non working side occurred in 48 out of 100 patients. There were 51.2% of the cases in the bruxism group and 46.0% in the non-bruxism group. Statistically, there was no correlation between the bruxism and occlusal contact on non-working side. There was no difference according to sex.

Conclusion : There was no significant correlation between bruxism and occlusal contact on non-working side. The group function was the highest in the bruxism group when lateral excursion was occurred.
