ABSTRACT:The aim of this study was to check the orientation of ala tragus line with occlusal plane in different facial forms in dentulous subjects with the help of cephalograms. A total of 200 dentulous subjects (100 male and 100 female) were selected from Government Dental College, Srinagar in an age group of 18-25 years to obtain the lateral cephalograms. To determine the facial form, the bizygomatic width was measured using a digital caliper. The facial length was measured using digital caliper from Nasion to Gnathion (N‑Gn). Facial form was then obtained from the formulae (N-Gn/ Bi Zygomatic width)×100 and divided into euryprosopic, mesoprosopic and leptoprosophic. The results of this study demonstrated that in maximum percentage of the participants, the occlusal planes were parallel to lines joining the inferior borders of the ala of the nose and the middle parts of the tragus.
