| Abstract | ||
| Aim : The paper aims to evaluate the effect of teeth wear severity associated with bruxism on the con-dylar height asymmetry index among different gender using panoramic radiograph viewing technique. Materials and methods: One hundred fifty subjects were participate in this study. Seventy five were bruxers and seventy five were non-bruxers. Degree of tooth wear severity was graded using Smith and Knight method. The panoramic radiographs were taken for each patient using a panoramic apparatus to determine vertical mandibular height asymmetry indices by a method developed by Habets et al. Mann-Whitney U test, Kruskal-Wallis test and Pearson Chi-Square test were used to determine the possible statistically significant differences between groups set at (P ≤ 0.05).Results: The results showed there are significant differences between the vertical mandibular height asymmetry indices of the bruxers and non-bruxers subjects. The female bruxer subjects had the higher condylar index value than that of the male but statistically , there is no significant difference, while the severity of tooth wear had a signifi-cant different affect on the condylar indices. Conclusions: The results showed that the vertical man-dibular asymmetry indices were affected by the tooth wear associated with bruxer subjects. The bruxer subjects had the higher value than the non-buxer subjects and there is no significant difference of the condylar index of bruxer subjects among different genders. While , condylar index value increased significantly as the tooth wear severity grade increased. | ||
