title: Orthodontic root resorption of endodontically treated teeth.
abstract: The purpose of this study was to evaluate, radiographically, whether there is similarity in the apical root resorption found in endodontically treated teeth and untreated teeth when they are submitted to orthodontic treatment. From 2,500 treatment records examined, 16 patients were selected who had a maxillary central incisor treated endodontically before initiation of the orthodontic movement, and a vital homologous tooth (for control). Measurements were made by comparing the periapical radiographs taken before and after the orthodontic treatment. There was no statistically significant difference (p>0.05) in apical root resorption found in the endodontically treated teeth compared to the group of vital teeth.
