Background & Objective: The objective of this study was to investigate condylar asymmetry in a group of untreated Class II malocclusions and compare them with a control group of normal Class I malocclusion using Habets et al technique.
Materials & Methods: The study group consisted of 100 patients with class II Div 1 malocclusion (50males and 50 females), and a control group of 100 subjects with normal class I occlusion (50males and 50 females). Condylar, ramal, and condylar plus ramal asymmetry values were computed for all of the subjects on orthopantomograms. Data were analyzed statistically by means of Z-test to compare between normal occlusion and class II div 1 malocclusion for each male and female group.
Results & Interpretation: Significant difference was observed in condylar height, combined height and condylar asymmetrical ratio respectively when compared between normal classes I occlusion and class II div I malocclusion. Similarly significant differences was observed between condylar height, combined height and condylar asymmetrical ratio in males. However, all other asymmetrical ratios were insignificant. Similarly for females, condylar height, combined height and asymmetrical ratios were all insignificant.
Conclusion: Our study shows CAI value was significantly higher in Class II/1 malocclusion males when compared with normal Class I malocclusion. This malocclusion could act as a predisposing factor for having asymmetric condyles if left untreated.
