our primary objective was to measure root canal penetrations of aqueous antibacterial nano-chitosan (nano-cs), for the first time. the second objective was to compare and contrast such penetrations to those of chitosan (cs) itself, as well as sodium hypochlorite (naocl), chlorhexidine (chx) and ethylenediamintetraacetic acid (edta), at the routinely used concentrations. molar roots were split l...

STATEMENT OF PROBLEM Previous studies have shown discoloration of mineral trioxide aggregate (MTA) in contact with root canal irrigation solutions. However, there are limited data on colour stability of other calcium silicate-based materials (CSMs). OBJECTIVES This in vitro study aimed to evaluate the colour stability of three CSMs in contact with different irrigation solutions. MATERIALS A...

Root canal treatment encompasses thorough cleaning and shaping of the canal. Cleaning is achieved through proper instrumentation and irrigation for debridement and dis­ infection of the root canal system in addition to creating a suitable shape for complete three dimensional obtura­ tion. Various irrigants and medicaments have been used for cleaning root canals with different results. These in­...

INTRODUCTION The production of smear layer during canal instrumentation is thought to increase coronal microleakage even after canal obturation. Previous studies have shown that the type of irrigant does not necessarily affect the seal of the obturation. Our study aimed to evaluate the effect of three irrigation solutions (MTAD, citric acid and EDTA/NaOCl) on the coronal microleakage of root ca...

introduction: the aim of this study was to compare the antimicrobial effects of mtad, sodium hypochlorite (naocl) and their combination on endodontic micro-organisms. materials and methods: zone of inhibition (zi) and minimum inhibitory concentration (mic) were the techniques used. in zi technique blood agar plates were inoculated with organisms, paper discs were soaked with irrigants and maxim...

Aim: The purpose of this study was to determine the efficacy several irrigants and an aqueous extract Fructus mume in eradicating three kinds biofilm. Materials Methods: A three-species biofilm E. faecalis, P. gingivalis F. nucleatum were cultivated for one week on Thermanox™ plates. Each specimen immersed 8 minutes various irrigants: solution, buffered citric acid, sodium hypochlorite control ...

The extrusion of intracanal debris as well irrigants is a regular occurrence during root canal therapy; nevertheless, this issue has not been satisfactorily resolved by any instrument or method to date. Even if it's always possible, shaping irrigation should reduce the likelihood apical much possible. This because flare-ups may result from irritation that directed towards periapical tissues. Du...

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 treatmen...
