The association between traumatic dental injuries and atypical external root resorption in maxillary primary incisors.

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.

Parents' ability to recall past injuries to maxillary primary incisors in their children.

Aim: To evaluate the ability of parents to recall past injuries to their children's maxillary primary incisors.

Materials And Methods: Clinical and radiographic trauma-related major and minor signs observed in the first dental visit of 727 preschool children were recorded. Major signs included crown fracture, coronal discoloration, internal resorption, pulp canal obliteration, swelling, fistula, and periapical lesion.
