Abstract

Introduction: The aim of this study was to evaluate the contributory factors of external apical root resorption.
Materials and Methods: Sixty subjects who had undergone complete orthodontic treatment were selected.
The difference of the root length between pre and post-treatment was measured. The degree of root
resorption was scored according to the index proposed by Levander and Malmgren. 1 The mean root
resorption score (MRRS) was calculated. Mann Whitney test was done to compare the groups. Pearson
correlation was applied.
Results: There was no statistically significant difference in root resorption among males and females.
Tooth extraction was correlated with MRRS. Except for upper posterior teeth, the duration of treatment
was positively correlated with MRRS. For overjet, there was a positive correlation between upper and
lower anterior teeth and MRRS.
Conclusion: Orthodontic treatment should be carefully performed in patients who need extraction, great retraction of maxillary incisors and prolonged therapy.

Keywords: Root resorption, Fixed orthodontic treatment forces.
