Abstract :
Background: 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.
Materials and Methods: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.
Results: 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 teeth.
Conclusion: The 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.
