Biocompatibility of EDTA, EGTA and citric acid.
This in vivo study evaluated, through the physicochemical assay method for quantification of enhanced vascular permeability, the irritating potential of EDTA, EGTA, citric acid and saline. Thirty-two male Wister rats were anesthetized and four experimental sites were demarcated on their backs. Injections of 2% Evans blue (20 mg/kg) were administered intravenously into the lateral caudal vein. T...
متن کاملDemineralization effect of EDTA, EGTA, CDTA and citric acid on root dentin: a comparative study.
The purpose of this study was to biochemically compare the decalcifying effects of 1% EDTA (pH 7.4), 1% EGTA (pH 7.4), 1% CDTA (pH 7.4), 1% citric acid solutions (pH 1.0 and 7.4) and saline solution (control) on root dentin. Forty-eight single-rooted teeth were used in this study. The canals were instrumented by the step-back technique and the roots were randomly divided into six equal experime...
متن کاملEffect of sodium hypochlorite on dentin microhardness.
This study was designed to evaluate the effect on root dentin microhardness of 2.5% and 6% sodium hypochlorite solutions for various irrigation periods. Forty-two bovine roots were divided into seven groups. The control group was irrigated with saline. The experimental samples were continuously irrigated with 2.5% or 6% NaOCl for 5, 10, or 20 min. Microhardness was measured at depths of 500 mum...
متن کاملAntagonistic interactions between sodium hypochlorite, chlorhexidine, EDTA, and citric acid.
INTRODUCTION Root canal irrigants play a significant role in the elimination of microorganisms, tissue dissolution, and the removal of debris and smear layer. No single solution is able to fulfill these actions completely; therefore, their association is required. The aim of this investigation was to review the antagonistic interactions occurring when sodium hypochlorite (NaOCl), chlorhexidine ...
متن کاملEffect of QMix 2 in 1, BioPure MTAD and 17% Ethylenediaminetetraacetic Acid on Microhardness of Root Canal Dentin
Aim: To compare the effect of QMix, a mixture of tetracycline, citric acid, and detergent (MTAD), and ethylenediaminetetracetic acid (EDTA) on the microhardness of the root canal dentin. Materials and methods: A total of 30 single-rooted teeth were decoronated at 15 mm from the root apex. Root canal instrumentation using step back technique was done and the specimens were split into two halves ...
