INTRODUCTION Heating a sodium hypochlorite solution improves its effectiveness. The aim of this study was to measure the in vivo temperature changes of sodium hypochlorite solutions that were initially preheated to 66°C or at room temperature inside root canals during routine irrigation. METHODS Thirty-five root canals were prepared to ISO size 40 with 4% taper. A type K (nickel-chromium-nick...

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 against e. faecalis bacteria as a fi...

AIM The purpose of this study was to compare the antibacterial efficacy of three root canal irrigating solutions: An antibiotic containing irrigant, Chlorhexidine and Chlorhexidine + Cetrimide. METHODOLOGY 46 permanent maxillary central incisors were made into standardized segments and sterilized. 6 teeth were used to confirm sterility. The remaining 40 teeth were infected with Enterococcus f...

Transcription levels of the genes on X chromosome are regulated through the dosage compensation mechanisms. The dosage compensation complex (DCC) localizes to X chromosome and activates the transcription of target genes in male 2-fold more than in female. Drosophila maleless (MLE), an ATPase/helicase, is a component of the DCC and essential for the viability of male flies. However, the function...

OBJECTIVES The purpose of this study was to measure and compare the root canal cleanliness and smear layer removal effectiveness of Aquatine Endodontic Cleanser (Aquatine EC) when used as an endodontic irrigating solution in comparison with 6% sodium hypochlorite (NaOCl). MATERIAL AND METHODS Forty-five human teeth were randomly allocated to five treatment groups; the pulp chamber was accesse...

OBJECTIVES To eliminate microorganisms that are responsible for pulpal and periapical infections and to prevent reinfection of the root canal system an effective chemomechanical preparation by irrigants with sustained antimicrobial activity is beneficial. Hereby, we evaluated the residual antibacterial activity of MTAD after canal obturation at different time intervals. MATERIALS AND METHODS ...

The purpose of this study was to compare the effects of ultrasonication with ethylenediaminetetraacetic acid (EDTA) and a mixture of tetracycline isomer, an acid, and a detergent (MTAD) as final canal irrigants on the smear layer, debris and erosion scores. Fifty-eight extracted single-rooted human teeth were instrumented with ProTaper rotary files up to size F3. According to the final irrigati...

INTRODUCTION The purpose of this in vitro study was to assess the antifungal activity of final canal rinse with either three concentrations of sodium hypochlorite (NaOCl) (0.5, 2.6 and 6%), two concentrations of chlorhexidine (CHX) (2% and 0.2%), MTAD, Tetraclean, Hypoclean and Chlor-Xtra on Candida albicans (C. albicans) in a human tooth model. METHODS AND MATERIALS Two hundred and thirty fi...
