introduction: the purpose of this study was to compare the antimicrobial efficacy of sodium hypochlorite (sh) and calcium hypochlorite (ch) against enterococcus faecalis (e. faecalis) using quantitative real-time polymerase chain reaction (qpcr) analysis and also to compare their cytocompatibility on l929 murine fibroblasts using mossman’s tetrazolium toxicity (mtt) assay. methods and materials...

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 ...

apical extrusion of debris and irrigants during cleaning and shaping of the root canal is one of the main causes of periapical inflammation and postoperative flare-ups. the purpose of this study was to quantitatively measure the amount of debris and irrigants extruded apically in single rooted canals using two reciprocating and one rotary single file nickel-titanium instrumentation systems.sixt...

INTRODUCTION The purpose of this in vitro study was to assess the apical microleakage of AH26 sealer when three different root canal irrigant regimens were used. MATERIALS AND METHODS Eighty single-rooted human teeth were randomly divided into three experimental (n=20) and two control groups (n=10). NaOCl was used as irrigant during instrumentation, and apical patency was ensured in all teeth...

Sodium hypochlorite (NaOCl) in various concentrations is the most widely used endodontic irrigant, but it can be an irritant to vital tissues. There are several reports about the complications of irrigation with NaOCl during root canal therapy. Most of the complications are the result of accidental extrusion of the solution from the apical foramen or accessory canals or perforations into the pe...

The case reports describes non surgical healing in periradicular lesions.A conservative approach with 5.25% sodium hypochlorite was used for irrigation, and calcium hydroxide was used for the intra-canal dressing and 2% chlorohexidine as a final irrigant. Periapical healing was observed 1 month after obturation and continued in the 12-month recall. This report confirms that the large size of a ...

BACKGROUND Successful obturation in the primary teeth demands complete dryness of the root canal system. AIM The purpose of this study was to determine the effect of 95% ethanol as the final irrigant before root canal obturation in primary teeth. MATERIALS AND METHODS A total of 20 extracted primary mandibular canines were biomechanically prepared and pre-obturated volume of each tooth was ...

The aim of this study was to identify bacteria from the infected root canals of teeth with chronic apical periodontitis, and to evaluate the antibacterial effect of 0.2% chlorhexidine (CHX), as an irrigant, in reducing the microbial flora 48h after root canal preparation. A total of 44 subjects were randomly divided in the experimental group and the control group. The first bacterial samples fr...
