statement of problem: bacterial agents are the primary cause of pulpoperiapical diseases. therefore, an irrigating solution with proper antibacterial ability should be used to eliminate the bacterial agents during canal instrumentation. purpose: the aim of present study was to compare the antibacterial effect of 0.2% chlorhexidine to 0.5% sodium hypochlorite as canal irrigating solutions. mater...
introduction: the aim of this study was to compare the antimicrobial effects of 2.5% sodium hypochlorite (naocl), 2% chlorhexidine gluconate (chx) and biopure mtad (mtad) on enterococcus (e) faecalis -contaminated root canals of human extracted teeth. materials and methods: seventy human intact extracted single-rooted teeth with straight root canal randomly divided into 5 groups: positive contr...
objectives: the aims of this study were to test whether lightening of the overexposed radiographs improve determination of endodontic files length and whether lightened radiographs are comparable with ideally exposed radiographs. material and methods: four dried human skull coated with soft tissue-equivalent wax used for exposing radiographs of the upper molars. first, the endodontic file was p...
i ntroduction: due to the complex anatomy of the root canal system and high surface tension of common root canal irrigants (rci), conducting an investigation on rcis containing surfactants is a priority. the aim of this in vitro study was to verify the antibacterial potential of rci with low surface tension in root canals infected with enterococcus faecalis ( e. faecalis ). methods and material...
introduction: bacteria are the primary etiology of pulpal and periradicular pathosis. in endodontically treated teeth with persistent infections only one or a few bacterial species are present of which the most important is enterococcus faecalis. the aim of this study was to compare antibacterial efficacy of canal disinfectants including 5.25% sodium hypochlorite, 2% chlorhexidine, mtad (a mixt...
Background and Aim: Hepatitis B virus (HBV) is an important infectious agent in denti-stry necessitating the use of disinfectants to prevent its transmission. This study compared the efficacy of 2/100 sodium hypochlorite disinfectants prepared from 5% solution manufactured by four different manufacturers namely Ashimashi, Paknaz, Vitex and Active for disinfection of surfaces infected with HBV. ...
INTRODUCTION Formocresol is widely used in primary teeth pulpotomies; however it is known to have several side effects. The purpose of this study was to assess pulpal changes of primary teeth pulps after pulpotomy with sodium hypochlorite and formocresol. MATERIALS AND METHODS In this randomized clinical trial, 22 teeth were selected. These teeth were randomly divided into 2 groups (formocres...
BACKGROUND The current disease outbreak caused by the Ebola virus Makona variant (EBOV/Mak) has led to unprecedented morbidity and lethality given its geographic reach and sustained transmission. Sodium hypochlorite and ethanol are well-accepted decontamination agents, however little published evidence supports the selection of appropriate concentrations and contact times. The present study add...
HYPOTHESIS The anti-infective actions of povidone-iodine (PVI) and sodium hypochlorite enemas are different. DESIGN Prospective, randomized, single-blind study. SETTING Multicenter. PATIENTS Five hundred seventeen consecutive patients with colorectal carcinoma or sigmoid diverticular disease undergoing elective open colorectal resection, followed by primary anastomosis. INTERVENTION All...
AIM Sodium hypochlorite is the most commonly used endodontic irrigant because of its antimicrobial and tissue-dissolving activity. The aim of this study was to evaluate and compare the effects of concentration, temperature, and agitation on the tissue-dissolving ability of sodium hypochlorite. In addition, a hypochlorite product with added surface active agent was compared with conventional hyp...
