– The present study is a clinical and radiographic follow‐up investigation of 103 patients with 213 traumatized primary teeth. The re‐examination comprised a clinical and radiographic evaluation of involved permanent teeth after complete eruption. All disturbances in mineralization and morphology of these teeth were recorded. A multivariate analysis was applied to examine the relationship between clinical factors associated with the injury in the primary dentition and later disturbances among permanent successors. Disturbances in the permanent dentition were found in 88 teeth (41 %), and these complications were significantly related to age of the patient at time of injury, the type of injury sustained in the primary dentition, as well as the presence of an associated fracture of the alveolar bone.
