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(More)
The purpose of this study was to compare the antimicrobial activity of a plant-derived extract (2 percent Rosa damascena extract) with 5.25 percent sodium hypochlorite (NaOCl) and 2 percent chlorhexidine (CHX) on selected endodontic pathogens. The minimum inhibitory concentrations (MICs) of 2 percent rose extract and 2 percent CHX for test microorganisms,(More)
The purpose of this study was to determine the time required for anaerobic bacteria in natural human saliva to contaminate root-filled teeth. Thirty-two single-rooted teeth were cleaned, shaped, filled, and exposed to human saliva for 120 days. Teeth that had not leaked were subjected to polymerise chain reaction examination. Sixty-six percent of the(More)
INTRODUCTION Sodium hypochlorite (NaOCl) is an effective antimicrobial irrigant, however its toxic effects and deterrent odor are not ideal. Carvacrol is an edible plant extract with anti-inflammatory and anti-bacterial properties that is effective against Enterococcus (E) faecalis. The aim of this study was to evaluate Carvacrol's antibacterial efficacy(More)
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(More)
Received:31 October 2008 Accepted:11 March 2009 Abstract: Objective: The aim of this in vitro study was to compare the coronal microleakage between Streptococcus sanguis per se and a mixture suspension of E. faecalis and C. albicans in root canals filled with Gutta-percha and either AH 26 or AH Plus sealer. Materials and Methods: One-hundred and ten(More)
