The aim of this study is to compare the surface tension of four common endodontic irrigants: Moltendo EDTA 17%, Cetrexidin, Smear Clear, Sodium hypochlorite 5.25%, with the surface tension of MTAD and Tetraclean. Freshly produced MilliQ water was used as a reference. All measurements were performed following the Wilhelmy plate technique, using a Cahn DCA-322 Dynamic Contact Angle Analyzer at th...

AIM This study was conducted to evaluate the antimicrobial activity of 5.25% sodium hypochlorite (NaOCl), 2% chlorhexidine (CHX) and BioPure MTAD when used as a fnal rinse against Enterococcus faecalis. MATERIALS AND METHODS Sixty single-rooted premolars were biomechanically prepared, inoculated with E. faecalis and divided into various groups. These were then irrigated with the test irrigant...

OBJECTIVE The objective of this study was to compare the ex-vivo sealing ability of Resilon/new Epiphany (SE) sealer to that of gutta-percha/AH-Plus following smear layer removal with EDTA or MTAD. STUDY DESIGN One hundred extracted single-rooted human teeth were divided into 4 experimental groups and 2 positive and negative control groups. EDTA was used in groups 1 and 2. In groups 3 and 4 M...

OBJECTIVES The purpose of this study was to evaluate the capacity of BioPure MTAD to induce genetic damage in vitro. Genotoxicity was assessed by the single cell gel (comet) assay. METHODS Chinese hamster ovary (CHO) cells or murine fibroblasts cells were exposed to increasing final concentrations ranging from 0.1 a 10%. All treatments were performed for 1 hour at 37 degrees C. The negative c...

OBJECTIVE To evaluate the antimicrobial effect by measuring the minimum inhibitory concentration MIC and minimum bactericidal concentration MBC of propolis, BioPure MTAD, 5% sodium hypochlorite (NaOCl), and 2% chlorhexidine CHX on Enterococcus faecalis (E. faecalis) and Candida albicans (C. albicans) in vitro. METHODS This study was performed in the Faculty of Dentistry and Pharmacy at Erciye...

Mechanical instrumentation of root canals produces a smear layer that adversely affects the root canal seal. The aim of this study was to evaluate efficacy of MTAD and citric acid solutions used with self-adjusting file (SAF) system on smear layer. Twenty-three single-rooted human teeth were used for the study. Canals were instrumented manually up to a number 20 K file size. SAF was used to pre...

AIM The present study sought to compare the antimicrobial efficacy of 3% NaOCl, Biopure MTAD (Tulsa Dentsply, Tulsa, OK) and Brazilian ethanolic extract of propolis (EEP) against Enterococcus faecalis (E. faecalis). METHODOLOGY The study utilized 55 extracted human permanent teeth with single root canal. The samples were decoronated, instrumented and sterilized. The teeth were infected with E...

Objectives. To evaluate and compare the antifungal efficacy of 1.3% NaOCl/MTAD with 2.5% sodium hypochlorite (NaOCl), 2% chlorhexidine gluconate (CHX), and iodine potassium iodide (IKI). Materials and Methods. Fifty-two single rooted teeth were used which were divided into four groups with 10 teeth in each group: 2.5% NaOCl, 2% CHX, IKI, 1.3% NaOCl/MTAD, and physiologic saline. Two teeth served...
