Dilaceration of Mandibular Central Incisor: a case report

Abstract

Dilaceration of teeth can ocur as a result of trauma to its primary predecessors. Crown dilaceration is more rare than root dilacerations. This report describes a rare case of crown dilaceration of the mandibular central incisor caused by trauma. Periapical radiography and cone beam computed tomography scans revealed a severe crown dilaceration in the labial direction. After conventional root canal treatment, a glass fiber-reinforced post was placed and the tooth was restored using the original crown which was removed from the root before root canal obturation. One year after the treatment, the tooth was clinically intact without mobility and there was no sensitivity during percussion. Radiographic examination revealed that the periodontal tissues were healthy and there was no sign of root resorption. It was concluded that correct diagnosis and prompt treatment help to achieve desirable esthetics and function for crown dilecaration.
