Introduction: To radiographically evaluate the prevalence, extend and severity of root resorption in teeth adjacent to the cleft area after secondary alveolar bone graft. Methods: Radiographs of 200 individuals with unilateral and bilateral cleft lip, alveolus and palate were analyzed to investigate the presence of root resorption related with the bone graft. A total of 1315 radiographs were analyzed (periapical, occlusal and panoramic radiographs) obtained from 200 individials with complete unilateral or bilateral cleft lip and palate submitted to one graft surgery, available from the Radiology Section files of our institution. Results: Among the 200 individuals, 33 had external root resorption. Among these, 15 were present on preoperative radiographs, and 18 only after bone graft. Overall, 30 resorptions were located on the apical root third and 3 on the cervical third; the left central incisor was the most affected. No root resorptions were observed in the middle root third and no resorption affected more than one third. There was no statistically significant difference between age at the alveolar bone graft surgery and the presence of external root resorption. Conclusions: The prevalence of root resorption in teeth adjacent to the cleft area in individuals submitted to bone graft was low (16.5%). The apical root third was the most common location of external root resorption, and no resorption affected more than one root third.
