INTERACTION BETWEEN SODIUM HYPOCHLORITE AND ETIDRONIC ACID AS ROOT CANAL IRRIGANTS

An endodontic treatment consists of removing all contents of the root canal system before and during shaping. Irrigation is presently the best method for the removal of tissue remnants and dentin debris during instrumentation. The adjunctive use of chelating agents such as EDTA, Etidronic acid helps to remove and prevent the formation of the smear layer associated with root canal instrumentation. Meanwhile Sodium Hypochlorite solution is amongst the strongest disinfectants known, with antibacterial, sporicidal, antifungal and antiviral properties. The aim of this study is to determine the interaction between Sodium Hypochlorite and Etidronic acid as root canal irrigants.
