Crown–root Fractures

Treatment of Crown Root Fractures

A crown–root fracture extends below the Cementoenamel Junction .It may or may not affect the pulp.

 

Diagnosis is made by clinical examination, mobility testing, and radiographic examination. If the fragment is still kept in place by fibers of the periodontal ligament,the patient will generally complain about sensitivity to pressure and/or percussion due to the slight mobility of the fragment. Otherwise, if the fragment is lost, the tooth will react like an enamel–dentin fracture with or without pulpal involvement

Treatment and Prognosis




Crown–root fractures have immediate implications for the endodontic, restorative,and periodontal prognosis due to the subgingival position of the line of fracture.Treatment objective must, therefore, be aimed at exposing the fracture margins juxtagingivally or supragingivally, so that all clinical procedures can be managed with strict moisture control and bleeding control.The prognosis of the tooth may also be improved through better plaque control by the patient at the level of the fracture. This very often implies a multidisciplinar y approach with an endodontist, an orthodontist, a periodontist, and a prosthodontist.
