Root Resorption in Individuals With Self-Ligating and Conventional Bracket System
Objectives: The aim of this study was to compare the effects of self-ligating and conventional bracket system on root resorption and dentoalveolar structures in patients with skeletal Class I and moderate crowding.
Methods: Total of 72 patients included in the study. The mean age of groups were 14.1 ± 2 and 14.4 ± 2 years respectively. No significant difference was found between the groups in terms of age and gender. To compare the effects of the two groups on root resorption and dentoalveolar structures, panoramic and lateral cephalometric radiographs of the patients taken at the beginning and final were used. While the changes in root-crown ratio were examined with the measurements made on the panoramic radiographs, dentoalveolar structures were examined with angular and linear measurements made on the lateral cephalometric film.
Results: The mean treatment duration of the self-ligating bracket group was 20.7 ± 6.4 months, and the mean treatment duration of the conventional bracket group was 20.2± 6.3 months, and there was no significant difference between the groups. When the final measurements of the groups were evaluated, IMPA showed a significant increase in the first group (p=0.012), but did not show a significant increase in the second group. The inclination of the upper incisors increased significantly in both groups. The root crown-ratios of the upper four incisors decreased in both groups, but there was no significant difference between the groups (p>005).
Conclusions: When the findings are evaluated, it can be said that the clinical efficiency and treatment efficiency of both bracket systems are similar.
