Background: Root resorption becomes often a nightmare for almost every practicing orthodontist.The present study was conducted to assess apical root resorption in patients undergoing fixed orthodontic treatment. Materials & Methods: The present study was conducted on 94 patients of age range 12-26 years of both genders. In all subjects, root and crownlengths were measured in pre- and post-treatment panoramic radiographs. Later on relative changes of the root length during treatment were calculated by a root-crown-ratio taking preandpost-treatment root and crown lengths into consideration. Results: Out of 94 patients, males were 50 and females were 44. Pre treatment showed that mean length of root in males was 7.4 mm and in females was 7.0 mm and during treatment it was 7.1 mm in males and 6.4 mm in females. The difference was significant (P< 0.05). Conclusion: Author found significant reduction in root length and significant root resorption in males and females when compared it during the orthodontic treatment.
Key words: Orthodontics, Root resorption, Root length.
