Developmental disturbance of maxillary lateral incisor after trauma

Traumatic injury to a primary tooth has a potential to damage the underlying permanent tooth germ. It may lead to developmental disturbance of permanent dentition. The impaction of the permanent maxillary central incisor because of the root dilaceration in children is rare. The purpose of this paper is to report a developmental disturbance of a permanent right maxillary lateral incisor in a 12-year-old girl with a history of trauma at an early age.
