Abstract
Cephalometric norms are extremely useful to the orthodontist for providing guidance during diagnosis and treatment planning. But they are subjected to variability in morphologic characteristics in different ethnic and racial groups. The study was conducted on 76 subjects of 18-28 years of age with class I occlusion with acceptable facial profile. Standardized lateral cephalograms were taken in a natural head position and analyzed.North Indians exhibit increased facial convexity, greater mandibular prognathism, more obtuse lower face- throat angle and greater amount of upper lip - lower lip protrusion. Males showing larger cranial base length, vertical positioning and length of maxilla, ramal length, and the chin prominence. On dental analysis, females tend to have lesser proclined anterior teethThe present study was an attempt to provide better knowledge of facial morphology in the North Indians hence a comprehensive treatment planning can be done based on the norms derived for the correction of skeletal discrepancies.
