Comparative evaluation of apical root resorption during orthodontic treatment
Mariya Qadir, Mohammad Mushtaq

Background: The present study was conducted to assess apical root resorption after orthodontic treatment. Materials & Methods: 20 patients requiring orthodontic treatment were divided into two groups. Each group had 10 patients. Group I patients received treatment with conventional fixed orthodontic appliances. Group II patients received treatment with the removable orthodontic appliances. ARR on each tooth was calculated as the difference of tooth length before and after orthodontic treatment. Results: Root resorption in maxillary central incisor was 70.2% in group I and 84.5% in group II. Maxillary Lateral Incisor had 69.7% in group I and 87.2% in group II, maxillary canine had 46.8% in group I and 80.4%, mandibular central incisor had 62.4% group I and 76.2% in group II, mandibular lateral incisor had 54.7% in group I and 87.2% in group II and mandibular canine had 57.1% in group I and 82.9% in group II. The mean ARR in maxillary central incisor was 0.27 and 1.24, at maxillary lateral incisor was 0.24 and 1.32, at maxillary canine was 0.15 and 1.52, mandibular central incisor was 0.20 and 0.64, at mandibular lateral incisor was 0.06 and 1.04 and at mandibular canine was -0.07 and 1.04 in group I and II respectively. The difference was significant (P< 0.05). Conclusion: Fixed appliances resulted in less apical root resorption as compared to removable appliances. Key words: Removable appliances, fixed appliances, Root resorption
