Evaluation of external apical radicular reabsortion in the upper and lower teeth in orthodontic treatment

Resumo

The aim of this study was to evaluate external apical root resorption in the upper and lower teeth during orthodontic treatment. Material and methods: Periapical radiographs of 37 patients (22.05 years) of both sexes were evaluated by two radiologists at the beginning of orthodontic treatment, after the alignment and leveling phase, and at the end of orthodontic treatment, and classified according to the severity of root resorption. Results: The results indicated that root resorption was present in most of the dental groups evaluated at the end of treatment (p <0.05). with a relationship to malocclusion type, root shape, and apical shape, while treatment time affect the process of root resorption in some dental groups evaluated. It was observed that the greater the degree of dental crowding at the beginning of treatment, the higher the incidence of root resorption at the end. Conclusion: Based on the results of this study, it is concluded that there is a need for a radiographic protocol involving all teeth before and after the alignment and leveling phase.
