Root canal cleaning and shaping

Abstract

Root canal treatment is a frequently performed dental procedure and is carried out on teeth in which irreversible pulpitis has led to necrosis of the dental pulp. The speciality of endodontics encompasses numerous elements, but the use of a variety of instruments to shape root canal systems probably challenges the clinical time of practitioners more than any other. Removal of the necrotic tissue remnants and cleaning and shaping of the root canal are important phases of root canal treatment. Treatment options include the use of hand and rotary instruments and methods using ultrasonic or sonic equipment. Rotary root canal instruments manufactured from nickel-titanium alloy have proved to be a valuable adjunct for root canal therapy. But in certain cases such as in the presence of curved root canals hand filing becomes necessary. This article aims to explore various methods and instruments used in cleaning and shaping of Root canal system.
