CONTINUOUS CHELATION – A BIOLOGICAL AND CLINICAL UPGRADE OF ROOT CANAL TREATMENT STRATEGY IN ORAL REHABILITATION

Abstract

In current endodontic practice the root canal irrigation by using sodium hypochlorite as primary irrigant of choice coupled subsequently with a chelating agent, usually EDTA, is a crucial mean of cleaning and disinfection of endodontic system. Continuous chelation is a new paradigm relied on the increased role and efficacy of irrigation in root canal treatment. This novel approach of irrigation replaces the alternative use of irrigants according to present accepted treatment protocols by sole irrrigant flushing with a chair side mixture of sodium hypochlorite and a weak chelator, mainly etidronate (Dual Rinse HEDP). Continuous chelation is not inferior to the antimicrobial activity of sodium hypochlorite, allows the dissolution of pulp remnants and removal of smear layer and shortens the time required for chemomechanical treatment of the root canals.
