AIM To evaluate the antimicrobial effect of a diode laser irradiation, photo-activated disinfection (PAD), conventional and sonic activated irrigation with 2.5% sodium hypochlorite (NaOCl) on Enterococcus faecalis. METHODOLOGY Root canals of 120 human extracted teeth with single straight canals were prepared with ProTaper files, sterilized, contaminated with an E. faecalis suspension and incu...

Aim: The aim of this study was to evaluate the effectiveness of two instrumentation and irrigant techniques in smear-layer removal from root canals. Methodology: Thirty single-rooted teeth were randomly divided into two groups. Group 1 (continuous irrigation) was prepared using Selfadjusting file, and group 2 (manual irrigation; conventional needle irrigation) was prepared using with ProTaper f...

INTRODUCTION Oval-shaped root canals might represent a great challenge for proper disinfection. This study compared the capability of a newly developed instrument, the self-adjusting file (SAF), and rotary nickel-titanium (NiTi) instrumentation to eliminate Enterococcus faecalis populations from long oval root canals of extracted human teeth. As a secondary purpose, the ability of a modificatio...

The article deals with one of the most important problems mechanization rural and economic work on state irrigation canals ensuring their high-quality functioning. Irrigation canals, water intakes hydraulic structures are destructed deformed from natural climate artificial factors. A large capacity bucket shovel form equipped roller designed for cleaning lined silting sediment was considered. l...

AIM To compare the efficacy of irrigation protocols on the removal of triple antibiotic paste (metronidazole, ciprofloxacin and minocycline) (TAP) from artificial grooves in root canals. METHODOLOGY Root canals in 72 extracted single-rooted teeth were prepared using ProTaper rotary instruments up to size F5. The roots were split longitudinally and a standardized groove was prepared in the api...

BACKGROUND To determine the antibacterial effect of photodynamic Therapy on Enterococcus faecalis (E. faecalis) biofilms in experimentally infected human root canals in primary infections and endodontic retreatments. METHODS One hundred and sixty single-rooted extracted teeth with one root canal were prepared using ProTaper instruments. Seventy specimens were left without root canal filling a...

INTRODUCTION Effective debridement of the root canal system with chemical irrigants prior to obturation is the key to long-term success of endodontic therapy. The purpose of this study is to compare the antibacterial activity of 2.5% sodium hypochlorite (NaOCl) and 2% iodine potassium iodide (IKI) solutions as intracanal disinfectant in infected root canals during one-visit endodontic treatment...
