The efficacy of ultrasonic irrigation in endodontics: A review

Abstract

Debridement of the root canal system is essential for endodontic success. Irrigation is a vital part of root canal debridement. It is impossible to shape and clean the root canal completely because of the intricate nature of root canal anatomy. The triad of biomechanical preparation, pulp space sterilization and three-dimensional obturation is the hallmark of endodontic success. Complete disinfection of the pulp space cannot be achieved with most sophisticated instrumentation techniques. The role of irrigants in obtaining this goal cannot be underestimated. Optimal irrigation is based on the combined use of two or several irrigating solutions, in a specific sequence. However, currently there is no universally accepted standard irrigation technique. The aim of this article is to review armamentarium and various irrigants in endodontic practice.
