Abstract

Traumatic injuries in the young permanent dentition are common, but root fractures, defined as fractures involving dentin, cementum and pulp, are relatively uncommon. Appropriate management of root fracture involves repositioning the coronal portion of the tooth fragment and firm immobilization with a splint for 2 to 3 month. Root canal treatment should not be initiated until the sign of necrosis or resorption are apparent because in most cases, the apical fragments maintain their vitality. The following case report describes a patient with root fractures injured three times over the period of 7 years. The results, clinically and radiographically, were acceptable, but long term periodic evaluation is required.

Key Words: Root fracture, Traumatic root fracture, Upper permanent central incisor
