A tooth requiring root canal treatment (RCT) has often previously experienced caries, trauma, or restoration. RCT further injures the tooth through multiple mediums, including quantitative removal of tooth structure for endodontic access, qualitative deterioration of tooth structure via root canal irrigants, and de-innervation leading to reduced neurosensory feedback to occlusal loading. Subsequently, the root-filled tooth is at significantly increased risk of (non-restorable) fracture and requires careful restorative consideration. Part 3 of this series outlines key factors to consider when planning restoration of root-filled posterior teeth.

摘要

A tooth requiring root canal treatment (RCT) has often previously experienced caries, trauma, or restoration. RCT further injures the tooth through multiple mediums, including quantitative removal of tooth structure for endodontic access, qualitative deterioration of tooth structure via root canal irrigants, and de-innervation leading to reduced neurosensory feedback to occlusal loading. Subsequently, the root-filled tooth is at significantly increased risk of (non-restorable) fracture and requires careful restorative consideration. Part 3 of this series outlines key factors to consider when planning restoration of root-filled posterior teeth.
