Tooth discolouration due to endodontic materials and Procedures

Abstract

The appearance of the dentition is of great importance to a large number of people. There is an increase in interest in treatment of tooth staining and discolouration in recent times. Correct diagnosis of the cause of tooth discolouration is important in determining the treatment outcome. In order to make a correct diagnosis and to prevent iatrogenic causes of tooth discolouration, it is imperative that we possess an adequate knowledge of the various sources of tooth discolouration, including those that occur due to the use of certain restorative and endodontic materials. This review article summarises the causes and mechanisms of tooth dicolouration and staining caused by various endodontic materials.
