STUDY OF THE EFFECT OF Nd : YAG LASER AND ENERGY LEVELS REQUIRED TO STERILIZE ROOT CANALS AND ITS EFFECT ON THE PERMEAPILITY OF THE DENTINAL TUBULES

Abstract

With the introduction of laser to the field of dentistry, a great attention was directed towards it's ability to vanish completely all the intracanal microorganisms before root canal obturation in an attempt to improve endodontic treatment procedures. This study was conducted to study; the thermal effects of intracanallasing with Nd:YAG laser on the extemal tooth surface and to establish safe energy levels to be delivered into root canal to sterilize infected root canal. As well as studying the effect of laser irradiation on the permeability of the dentinal tubules of the root canal wall.
