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).
@ES The obtained results were as follows :
@EN 1. There was very high significant correlation between 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 was 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 retruded 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 corrllation 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 with CDI, DI.
