Atypical root resorption ( ARR ), which is observed on radiographs of primary incisors, has been reported in the dental literature to result from digit sucking; thus ignoring any association between ARR and traumatic dental injuries ( TDI ). The purpose of this study was to evaluate and compare the contributions of sucking habits and TDI to external ARR in primary incisors. A history of dental trauma was assessed based on clinical and radiographic findings. Periapical radiographs of the premaxilla were evaluated for the presence of ARR . The presence or history of sucking habits was based on parents' report. Data were collected from files of 727 patients with a mean age of 52 months. Sixty‐four children (8.8%) presented ARR in one or both central incisors. All 64 had experienced some type of TDI . Five hundred and forty‐nine (76%) of the children had sucking habits; of them, 501 were pacifier‐suckers and 48 digit suckers. Digit sucking was found in only 4 (6%) of the 64 children presenting ARR . These findings support the association of traumatic dental injury, and not of digit sucking, with ARR in primary incisors.
