Abstract

Objective: Different ethnic groups present variations in the various cephalometric analyses that are performed to determine the sagittal relation. This study is aimed at establishing the norms for Beta angle and Yen angle in Maratha population and to evaluate their reliability in sagittal malocclusions from amongst select local population.
Materials and Method: A total of 120 samples were divided into three categories. 60 samples of Class I normal occlusion (30 males and 30 females) were used to establish the norms. 60 samples with skeletal Class II and Class III relation were used for checking the reliability of the established norms. Lateral cephalogram of all the samples was procured and tracings were done to calculate ANB Angle, Wits appraisal, McNamara differential, Beta angle and Yen angle. Oneway ANOVA was done to determine the means of Beta and YEN angle in Maratha population.
Results: The Maratha population norms for Beta angle is 31.50 +/- 2.70 and for YEN angle is 122.20 +/- 2.90. The values less than this indicate Class II relation and more than this indicate Class III relation.
Conclusion: The established norms are reliable and comparable with the local population with no significant difference between the genders.
