Aim of the studyː to find if apical root resorption is related to orthodontic treatment time, type of appliance used and which are the most susceptible teeth to develop this type of resorption. Material and methodsː 70 patients (27 males and 43 females) selected from patients reffered for an orthodontic treatment at the Orthodontic Department of Faculty of Dentistry, University of Medicine and Pharmacy from TirguMures. The mean age at the beginning of treatment was 15.11 years for males and 14.67 years for females subjects. At the end of treatment, on their panormaic radiographs it was measured apical root resorption on incisors, premolars and molars in the upper and lower arch. Resultsː Root resorption was significantly (p< 0.05) correlated with fixed appliance treatment (49 percent). Patients with the longest treatment periods presented with significantly (p<0.05) more grade 2 resorptionː 28 months (± 2.6 SD) in the upper arch and 30 months (± 3.2 SD) in the lower arch. In the patients with the lowest treatment period (16 months in the maxilla and 18 months in the mandible arch) it was found no resorption. In the upper arch most of the patients (22.22 % males and 18.6% females) showed a grade 2 resorption in the incisor area. Root resorption of the premolars was seen in 18.5% of the male patients (7.4% with grade 2 ) and in 16.26 % of the female patients (6.97 with grade 2). Conclusionsː There is a high correlation between the orthodontic treatment time and apical root resorption. Most exposed to this process are incisors from bot, upper and lower arch. Less resorption was noticed in the premolar area.
