This book entitled "Bonding in Endodontics". Despite major simplifications in dental adhesion, Bonding to root canal dentin remained as an unpredictable goal due to various clinical factors influencing the procedure. A thorough understanding of the physiopathology of the pulp-dentine complex, physical properties, biocompatibility of adhesive materials and techniques used in Bonding to root canal dentin improves treatment outcome resulting in long-term success. In this aspect successful endodontic treatment is closely intertwined with adhesive dentistry. The technological boom in the art and science of endodontics has provided various newer adhesive systems and restorative materials required for the success of root canal treatment through bonding to root canal dentin. Properly performed endodontic treatment is the corner stone of restorative or reconstructive dentistry.
