Newer Endodontic irrigation devices: An update

Abstract

The ultimate aim of endodontic therapy is thorough debridement of root canal system. The aim of this review is to give a brief description of endodontic irrigation devices and their efficacy in root canal therapy. Recently developed irrigation devices and their application mode also discussed. Mechanism of these devices and the phenomenon that governs the irrigation efficacy discussed briefly. 5 Irrigation allows for cleaning beyond what might be achieved by root canal instrumentation alone so it is an essential part of root canal debridement. Till date none of the irrigant posses ideal quality that is why in contemporary endodontic practice, dual irrigants such as sodium hypochlorite (NaOCl) with ethylenediaminetetraacetic acid (EDTA) or chlorhexidine (CHX) are often used as initial and final rinses to complement the shortcomings that are associated with the use of a single irrigant. 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. Various methods have been developed in order to provide effective delivery. These systems might be divided into 2 broad categories, manual agitation techniques and machine-assisted agitation devices. The objective of this review was to present an overview of contemporary irrigation methods available in endodontics. II. Manual irrigation techniques Manual irrigation system using needles is still widely accepted by both general practitioners and endodontists. In this technique the dispensing of an irrigant into a canal through needles/cannulas of variable gauges, either passively or with agitation. The agitation might be achieved by moving the needle up and down the canal space. The design of these needles can be closed-ended, side-vented channels. III. Max-i-probe
