(Discoloration Potential of Two Materials Used in Regenerative Endodontics and Efficiency of Different Internal Bleaching Techniques (An in vitro study

Abstract

Regenerative endodontic therapy is a developing field in endodontics in which the treatment of immature permanent teeth with infected root canal systems using regenerative endodontic protocols often results in continued root maturation and apical closure. These protocols involve the application of calcium silicate material in contact with blood that leads to coronal discoloration and esthetic problem in most cases. The aim of this study was to evaluate the discoloration potential of MTA and Biodentine which are commonly used as regenerative materials as well as introducing and evaluating a new internal bleaching technique using laser application to overcome the esthetic problem.
