Incomplete tooth fracture following root-canal treatment
Discussion - References.

Complete or incomplete tooth fracture can arise in root-filled teeth unless adequate care is taken during preoperative assessment, during instrumentation and filling of the root-canal system, or in the design of the eventual coronal restoration. Whilst treatment is being performed, the root-canal system should be closely examined for evidence of any fracture. The operator needs to be aware of the risks of excessive removal of tooth substance during instrumentation and the exposure of such weakened teeth to mechanical forces during filling. Provision should be made for the tooth to be restored with adequate cuspal protection and mechanical strength immediately after completion of root-canal treatment, thereby preventing fracture initiation or propagation. Such restorations may take the form of a cast restoration, for example occlusal onlays, three-quarter crowns, or full-coverage crowns. The use of enamel-bonded and dentine-bonded composites (Wendt et al. 1987, Hansen & Asmussen 1990) or bonded amalgam restorations (Bearn et al. 1994) has been described. Root-filled teeth that have not been restored with an appropriate restoration have been shown to have a poor long-term prognosis (Ray & Trope 1995, Kirkevlang et al. 2000).
