Root Resorption of Endodontically Treated Teeth Following Orthodontic Treatment: A Cross-Sectional Study

BACKGROUND: Root resorption is an unwanted phenomenon occurring in a substantial population proportion these days. Hence, the current study was conducted to evaluate root resorption in endodontically treated teeth following fixed orthodontic treatment. MATERIALS AND METHODS: A total of 100 patients were enrolled. Only those patients were enrolled that were scheduled to undergo fixed orthodontic therapy. Pretreatment examination was done in all the patients, and their radiographs were obtained. Both orthopantomograms and peri-apical radiographs were taken. All the patients were recalled on follow-up, and radiographic examination was again carried out. Pretreatment radiographs and follow-up radiographs were compared. The incidence of root resorption was documented. The data were entered in an Excel sheet (Microsoft office version 2007) and analyzed using IBM SPSS software version 20. RESULTS: Root resorption was present in 30 patients. Among these 30 patients, 20 were male, whereas 10 were female. In 19 patients, root resorption was present in the maxillary arch, whereas in 11 patients, it was seen in the mandibular arch. The most common tooth involved with root resorption was premolars, followed by anteriors and molars. CONCLUSION: The risk of root resorption is higher in endodontically treated teeth under the influence of orthodontic forces.
