Objective: the objective of the study was to compare the frequency and amount of root resorption after 6 months of fixed orthodontic treatment in crowding and non-crowding orthodontic patients
Methods: this cross sectional study conducted at the Department of Orthodontics, Alvi Dental Hospital, Karachi. The six month study was conducted from June - December 2008. Sample consists of 60 patients of two groups. Group A comprises of 30 patients of crowding in maxillary anterior teeth and Group B consisted of 30 patients of non crowding cases of maxillary anterior teeth. The data was collected through non probability purposive sampling. In preorthodontic phase [stage I], the apical root resorption was measured as a difference between length of tooth at pretreatment [T1] as compare to stage II [Postorthodontic stage] i.e. length of root six months after the orthodontic treatment [T2]. Subjective scoring of resorption was done from 0-4 with the help of apical root resorption index. Finally the root resorption was compared in between two groups i.e. crowding and non-crowding and data was recorded in a predesigned questionnaire
Results: in crowding group we found 27 [90%] cases with apical root resorption of less than 2mm as compared to non-crowding group, which had 21 [70%] cases. When compared the length of the tooth in stage II the average length was significantly higher in non-crowding group as compared to crowding [p<0.05]. In crowding group we found statistically significant difference in mean decrease length of tooth [mm] at T2 i.e after 6 months compared to mean tooth length [mm] [p<0.05] at T1. We estimated mean decrease of difference in length of T1 and T2 in crowding group compared with noncrowding group [p< 0.05]
Conclusion: there is significant difference [p<0.05] in mean length of tooth root in crowding and noncrowding patients after six months of orthodontic treatment
