A Study on the Correlation between Signs/Symptoms of the Craniomandibular Disorders and Possible Contribution Occlusal Factors

두개하악장애증상발현과 교합요인 사이의 상관성에 관한 연구

To evaluate the correlationship between sign/symptoms of craniomandibular disorder(CMD) and possible contributing occlusal factors, the author analyzed craniomandibular index(CMI), clinical dysfunction index(CDI) and occlusal index(Oi) obtained from 88 subjects (32 males, 56 females, mean age 28.7) consisted of 49 CMD patients(15 males, 34 females, mean age 28.7) and 39 non-CMD patients (17 males, 22 females, mean age 24.5). The obtained results were as follows : 1. There was very high significant correlation bebween CMI and CDI in total subjects (r=0.83, p<0.01) 2. There was very low correlation between working-side interference and TMJ noise which was observed as a statistically significant value(p<0.05). And also there ws very low correlation between nonworking side interference and muscle tenderness, CDI, dysfunction index(DI), palpation index(PI) which were observed as statistically significant value (p<0.01) 3. There was very low correlation between as ymmetry of tetruded contact position(RCP)-intercuspal position(ICP) slide and muscle tenderness, TMJ tenderness, TMJ noise, CMI, DI, PI which were observed as statistically significant values(p<0.05) 4. In general there was low correlation between Oi and muscle tenderness, CDI, CMI, DI, PI which were observed as statistically significant values (p,0.05). But Oi had a relatively higher correlation with muscle tenderness, PI than whith CDI, DI.
