Abstract

Background:  Evaluation of the width of condyle in temporomandibular joint (TMJ) in different malocclusions among subjects in age range of 18-25 years from central India. Material and Methods: The study comprised of 90 subjects divided into three groups of 30 subjects each belongs to skeletal class I (Group A), class II (Group B) and class III malocclusion (Group C) based on lateral cephalometric analysis. Cone beam computed tomography (CBCT) of the patients was taken of right side of TMJ to measure the width of condyle. Mean and Standard Deviation was recorded and subjected to statistical analysis. Tukeys post hoc analysis was applied for inter group comparison.  Results: Width of condyle was slightly more in class III subjects as compare to class I and II. It was 15.43±2.25 mm, 14.21±2.32 mm and 16.39±3.34 mm among skeletal class I, II and III patients respectively. There was statistically significant difference found in width of condyle between class I, II and III study subjects (p=0.0090). Tukeys post hoc analysis showed statistically significant difference between class II and class III subjects (p>0.05). Conclusion: Width of condyle was more in Class III skeletal pattern followed by Class I and Class II skeletal pattern. In different populations width of condyle may varies, so this variation in the healthy joints should be taken into consideration while planning any orthodontic treatment or to diagnose any underlying disease.
