However, currently there is no universally accepted standard irrigation technique. Today’s irrigation armamentarium presents a diverse variety of tools and techniques that can assist the practitioner in reducing bacteria and debris within the canal system. In selecting an irrigant and technique, consideration must be given to their efficacy and safety. Such a delivery system must have adequate flow and volume of irrigant to working length to be effective in debriding the canal system without forcing the solution into periradicular tissues. An improved delivery system for root canal irrigation is highly desirable. To accomplish these objectives, there must be an effective delivery system to working length. More importantly, these irrigants must be brought into direct contact with the entire canal wall surfaces for effective action, particularly for the apical portions of small root canals. However, there is no one unique irrigant that can meet al.,l these requirements, even with the use of methods such as lowering the pH, increasing the temperature, as well as addition of surfactants to increase the wetting efficacy of the irrigant. Īn ideal irrigant should reduce instrument friction during preparation, Facilitate dentin removal, Dissolve inorganic and organic tissue, Penetrate to canal periphery, Kill bacteria and yeasts and least irritating to the periapical tissues. These areas might harbor tissue debris, microbes, and there by-products, which might prevent close adaptation of the obturation material and result in persistent periradicular inflammation. Even with the use of rotary instrumentation, the nickel-titanium instruments currently available only act on the central body of the canal, leaving canal fins, isthmi, and cul-de-sacs untouched after completion of the preparation. ![]() ![]() It is impossible to shape and clean the root canal completely because of the intricate nature of root canal anatomy. Irrigation is a vital part of root canal debridement. Debridement of the root canal system is essential for endodontic success. ![]()
