The results of the study showed significant association between attrition and temporomandibular joint (TMJ) pain, muscle tenderness and restricted opening, (P Values were 0.008, 0.019, 0.037 respectively). Significant association was found between habit of grinding and pain, while eating or opening the mouth (P<0.012).
