Onauma Angwaravong, Rossarin Somprasong, Manussanunt Thangwongthawornkit


Dilaceration is defined as an angulation, deviation, sharp bend or curve in the linear relationship of the
crown of a tooth to its root. Mechanical injury to the primary predecessor tooth and idiopathic developmental disturbances can lead to the dilaceration of the underlying developing succedaneous permanent. The severity of dilaceration depends on various factors such as the direction, intensity of the force involved and the stage of development of the permanent tooth at the time of trauma. Dilaceration results in abnormal tooth morphology or unerupted tooth. Diagnosis of dilaceration is based on the history, clinical and radiographic findings. The appropriate management usually requires a multidisciplinary approach. The purposes of this article are to review related literatures regarding the prevalence, etiology, diagnosis, dental management of dilacerations and to report a case. The patient demonstrates a root dilaceration of tooth resulting in uneruption. The patient was successfully treated by surgical exposure of the tooth combined with orthodontic traction.
