I NTRODUCT ION The Er:YAG laser, emitting at 2940 nm, can be a valuable tool for root canal debridement and improved pathogen reduction during endodontic treatment. The ability to successfully negotiate and remove the smear layer and bacteria continues to be a challenge for nonsurgical endodontic treatment in root canal systems. Current instrumentation techniques use both hand and ultrasonic ir...

INTRODUCTION It has been demonstrated that organic content of the root canals can influence the antimicrobial capability of chemical irrigants. The aim of this study was to evaluate the effect of bovine serum albumin (BSA), as an organic material, on the antimicrobial activity of several intracanal irrigants. MATERIALS AND METHODS Bactericidal activity of Ethylenediaminetetraacetic acid (EDTA...

UNLABELLED Ideally root canal irrigants should have, amongst other properties, antimicrobial action associated with a lack of toxicity against periapical tissues. Sodium hypochlorite (NaOCl) is a widely used root canal irrigant, however it has been shown to have a cytotoxic effect on vital tissue and therefore it is prudent to investigate alternative irrigants. Sterilox's Aquatine Alpha Electro...

OBJECTIVE The aim of this study was to monitor the effectiveness of root canal procedures by using different irrigants and intracanal medication on endotoxin levels found in root canals of teeth with chronic apical periodontitis. MATERIAL AND METHODS Thirty root canals of teeth with pulpal necrosis associated with periapical lesions were selected and randomly divided into groups according to ...

BACKGROUND Interaction between local anesthetic solution, lidocaine hydrochloride (with and without adrenaline), and root canal irrigants such as sodium hypochlorite (NaOCl), ethylene diamine tetra-acetic acid (EDTA), and chlorhexidine (CHX) has not been studied earlier. Hence, the purpose of this in vitro study was to evaluate the chemical interaction between 2% lidocaine hydrochloride (with a...

INTRODUCTION The aim of this study was to compare the antibacterial effect of Persian green tea extract (GTE) and 2.5% sodium hypochlorite (NaOCl) against Enterococcus faecalis (E. faecalis) as an intracanal irrigant. METHODS AND MATERIALS Thirty freshly extracted teeth were instrumented and sectioned into mesial and distal segments. The specimens were put into wells containing 2 mL of E. fae...

BACKGROUND This study aimed to assess the push-out bond strength of mineral trioxide aggregate (MTA) to root canal dentin after irrigation with Smear Clear in comparison with 2.5% sodium hypochlorite (NaOCl), 2% chlorhexidine (CHX) and saline as commonly used root canal irrigants. MATERIAL AND METHODS The coronal and mid-root areas of maxillary anterior teeth were horizontally sectioned into ...
