Abstract

The aim of the research was to compare the mean measurements of the ramal height and gonial angle among the groups of third molar classified by Pell and Gregory’s and Winter’s classification. The measurements were done on the panoramic radiographs that included third molars on both sides of 338 patients, ages between 18-30 years. The samples were grouped into class, depth and angulations of the third molar. The comparisons of ramal height and gonial angle among each group were done using Kruskal Wallis test and one-way ANOVA. The average ramal height was 38.6 ± 4.16 millimeters. The average gonial angle was 121.8 ± 7.58 degrees. The third molars in class II, depth A and mesioangular positions were most commonly observed. The comparative analysis found the ramal heights and gonial angles were not different among the groups of the third molar classified by Pell and Gregory’s and Winter’s classification.
