Aim: This case report illustrates the multidisciplinary treatment of a 12-year-old boy with esthetic challenges and endodontic problems in his maxillary incisors after severe dental injury at the age of 2½ years.
Background: The close anatomic relationship of the primary tooth to the permanent tooth germ explains why traumatic dental injuries in primary dentition may affect the development of permanent teeth especially in the maxillary anterior region. Developmental defects of enamel (DDE) as well as crown/root dilacerations are often seen after displacement injuries such as intrusion or avulsion occurring at lower age.
Case description: A 12-year-old boy with severe discoloration and enamel hypoplasia of his maxillary incisors was treated with composite restorations. History of avulsion injury of teeth 51 and 61 at the age of 2½ years explained the DDE, the severe dilaceration, and delayed tooth eruption of tooth 21. Use of cone-beam computed tomography (CBCT) was decisive in diagnosis and treatment planning of esthetic concerns and endodontic complications.
Conclusion: Trauma to primary teeth taking place at early childhood may have severe consequences on permanent successors.
Clinical significance: Severe morphological variations in permanent incisors caused by dental injuries in the predecessor teeth require monitoring and multidisciplinary approach. Advanced three-dimensional radiographic imaging is useful in identification and treatment planning of such cases.
