Abstract

Aim: To assess and compare anteroposterior jaw dysplasia indicators i.e. (Wits-appraisal, ANB-angle, β(Beta)-angle, W-angle, YEN-angle and ?(Pi)-angle) in Angle's Class I molar relation subjects with normal overjet of central India.
Materials and Methods: Sum of 40 lateral cephalograms were traced in line with the inclusion criteria of Angle’s Class I molar relation subjects. Subjects had to be between the ages of 18 and 30 and have a normal overjet and aligned arches. We measured and compared the Wits-appraisal, ANB-angle, (Beta)-angle, W-angle, YEN-angle and Pi-angle. The statistical package for social sciences (SPSS) 20.0 version was used to examine the data. We used descriptive statistics. The Spearman's correlation coefficient was used to evaluate the correlation between the variables. Statistics were judged as significant at a p-value of 0.05. 95% of the confidence interval was chosen.
Results: The result showed descriptive statistical representation for the norms of Wits-appraisal, ANB-angle, Beta-angle, Yen-angle, W-angle, and Pi-angle for the Central India population. We found a high correlation of ANB-angle with YEN-angle, ANB-angle and Pi linear, ANB-angle and W-angle, Beta-angle and W-angle, YEN-angle and W-angle and Pi-angle and Pi linear.
Conclusion: Among the angles used for the comparative evaluation for the prediction of anteroposterior jaw dysplasia, W-angle and YEN-angle had the utmost accuracy, whereas Beta-angle had the least. Therefore, YEN-angle and W-angle are reliable in our practice in the prediction of anteroposterior jaw dysplasia in the Central India population.
