1. #2982 Comparisons of Periodontal Conditions Between the Habitually Chewing Side and the Non-habitually Chewing Side J. SUZUKI, M. KANAZASHI, K. GOMI and T. ARAI Tsurumi University,Dept. of Periodontics, JAPAN Abstracts Objective: In this study, we investigated the differences of periodontal conditions, which were tooth mobility and probing depth, between the habitually chewing side and the non-habitually chewing side. Materials and Methods: We examined 10 slight periodontal patients were employed as subjects (2 males and 8 females, aged 27-63 years) who had normal dentitions and 28 teeth except third molar, and they were finished initial preparation. The habitually chewing side was decided as follows. On the panoramic radiography, the fat and short type condyle side compared the other was decided the non-habitually chewing side. Furthermore, on the study models, higher curved of Spee was decided the non-habitually chewing side. All subjects were satisfied these two parameters in a same side. Measurements of tooth mobility and probing depth were examined by PERIOTEST(SIEMENS Co., Germany.) and William's probe (Hu-Friedy Co., U.S.A.) respectively. Statistical analyses were performed one -factor ANOVA. Results: Mean tooth mobility and probing depth in the habitually chewing side were 5.9±4.8(Total), 5.1±4.9(anterior teeth), 5.3±4.0(premolars), 7.7±4.9(molars) and 2.1±1.2mm(Total), 1.8±1.0 mm (anterior teeth), 2.0±0.9 mm (premolars), 2.6±1.4 mm (molars). In the non-habitually chewing side those were 6.3±5.8(Total), 4.6±3.7(anterior teeth), 6.5±4.3(premolars), 8.8±8.3(molars) and 2.1±1.2 mm (Total), 1.8±1.0 mm (anterior teeth), 2.2±1.2 mm (premolars), 2.5±1.3 mm (molars). There were no significant differences between the habitually chewing side and the non-habitually chewing side on tooth mobility and probing depth. Conclusion: There were no differences of mobility and probing depth between the habitually chewing side and the non-habitually chewing side. Objective In this study, we investigated the differences of periodontal conditions, which were tooth mobility and probing depth, between the habitually chewing side and the non-habitually chewing side. Materials and Methods We examined 10 slight periodontal patients were employed as subjects (2 males and 8 females, aged 27-63 years) who had normal dentitions and 28 teeth except third molar, and they were finished initial preparation. The habitually chewing side was decided as follows. On the panoramic radiography, the fat and short type condyle side compared the other was decided the non-habitually chewing side. Furthermore, on the study models, higher curved of Spee was decided the non-habitually chewing side. All subjects were satisfied these two parameters in a same side. Measurements of tooth mobility and probing depth were examined by PERIOTEST(SIEMENS Co., Germany.) and William's probe (Hu-Friedy Co., U.S.A.) respectively. Statistical analyses were performed one -factor ANOVA. Example:The habitually chewing side is right side Discussion Probing depth: There was a tendency that premolars on the non-habitually chewing side and molars on the habitually chewing side were deeper. Tooth Mobility: There was a tendency that anterior teeth on the habitually chewing side, premolars and molars on the non-habitually chewing side were larger. There was a tendency that tooth mobility and probing depth more increased to molars from anterior teeth on both chewing sides. We consider this reason is the chewing cycle that at first anterior teeth on both chewing side cut food rough, next premolars on the non-habitually chewing side crush these more small and at last molar on the habitually chewing side grind down these and swallow these Example:The habitually chewing side is right side Results Mean tooth mobility and probing depth in the habitually chewing side were 5.9±4.8(Total), 5.1±4.9(anterior teeth), 5.3±4.0(premolars), 7.7±4.9(molars) and 2.1±1.2mm(Total), 1.8±1.0 mm (anterior teeth), 2.0±0.9 mm (premolars), 2.6±1.4 mm (molars).

There were no significant differences between the habitually chewing side and the non-habitually chewing side on tooth mobility and probing depth. Conclusion There were no differences of tooth mobility and probing depth between the habitually chewing side and the non-habitually chewing side. PERIOTEST
