Abstract

I. Objectives Intracanal medicament with antibacterial action is required to maximize the disinfection of the root canal system. The purpose of this study was to evaluate the efficacy of 2% chlorhexidine digluconate(CHX) and controlled release device(CRD) containing 20% CHX and chitosan coating, compared to calcium hydroxide as intracanal medicament against E. faecalis. II. Materials and Methods One hundred and twenty intact freshly extracted bovine incisors were used and were 0.5% NaOCl. Middle 1/3 portion of roots were sliced into 4mm thick section and cementum was removed using diamond burs and external diameter was approximally 6mm.(omitted)
