To evaluate and compare the facial asymmetry and laterality of facial asymmetry in subjects with class I and class II molar relation using frontal photographs. The frontal photographs of 30 subjects of North Indian population were selected and divided into two Groups- Group I had 15 females with class I molar relation and Group II had 15 females with class II molar relation. Both groups were further subdivided into subgroup and b for evaluation of parameters of right and left side respectively. The photographs were cropped in Adobe Photoshop. 5 horizontal and 3 midline parameters were measured using Digimizer Software for evaluation of facial asymmetry. The data obtained were analyzed statistically using SPSS (version 16). When comparison of various parameters between subgroup of Group I and Group II Mid facial plane (Mfp) to Endocanthus and Chelion were higher on right side , Mfp to Ala of the nose and Gonion were higher on left side in Group I but difference was NS (statistically not significant). In Class II subjects, right hemiface was wider but statistically significant difference was seen only for Mfp to Exocanthus. All the parameters showed NS difference between Group I and Group II. Laterality of facial asymmetry was seen on left side in both groups with higher values in Group II than Group I but difference was NS. No conclusive result regarding wider hemiface was seen in Group I. Group II had a trend towards wider hemiface on right side. Laterality of facial asymmetry showed deviation towards left side and was more in Group II.
