Principles guiding the restoration of the root-filled tooth

Abstract

After determining restorability and subsequently endodontically treating teeth, the clinician should determine the likely forces that will be exerted on the tooth in function and, potentially, parafunction. A restorative material should be selected based on these forces, the remaining tooth structure, and patient acceptability, to provide an antimicrobial seal for the root canal filling and provide protection to the underlying tooth structure. A direct or indirect restoration constructed from an appropriately selected material, based on patient and material factors, should restore aesthetics and function with a reasonably predictable longevity.
