Background: Sodium hypochlorite produces free oxygen and radicals that cause damage to dentin collagen. Combination with thiosulfate the aim of improving root canal hygiene restoring oxidizing effect on surface.The apical third is most difficult part, due its narrower anatomy, curvature frequent branching canal. Method: The study used 30 specimens which were divided into 3 groups, group I was i...

OBJECTIVE To evaluate and compare the cleaning ability of the more biocompatible 1% sodium hypochlorite (NaOCl) with passive ultrasonic irrigation (PUI) to that of 2.5% NaOCl with syringe method irrigation. MATERIAL AND METHODOLOGY Thirty-six extracted permanent single-rooted mandibular premolar teeth were decoronated at the cemento-enamel junction and divided randomly into four groups (nine ...

Objectives: The present study aims to evaluate the effects of different concentrations ethylenediamine tetraacetic acid (EDTA) on smear layer removal in primary teeth by using scanning electron microscopy (SEM). Materials and Methods: was performed with 28 extracted upper incisors assigned into four main groups (n=7) as 5%, 10% 17% EDTA, 1% sodium hypochlorite (NaOCl). root canal surfaces (coro...

This study assessed the cross-sectional Knoop microhardness and flexural strength of root dentin exposed to different surface treatments with chemical agents after biomechanical preparation. Root canals from human canines were biomechanically treated and divided into eight groups (n=10) to receive one of the following dentin treatments: I. Deionized water (control); II. 5.25% Sodium hypochlorit...

Bonding composite resin to enamel of teeth affected by amelogenesis imperfecta (AI) is often problematic, especially in cases with poorly mineralized, friable enamel. Difficulty in bonding hypomineralized enamel can significantly limit the restorative and orthodontic treatment options for AI patients. In this report, we document a novel approach to bonding AI enamel by pretreating the tooth sur...

AIM To evaluate the effectiveness of two final irrigation techniques for the removal of precipitate formed by the interaction between sodium hypochlorite (NaOCl) and chlorhexidine (CHX). MATERIALS AND METHODS Sixty freshly extracted human maxillary incisor teeth were taken and randomly divided into three groups, containing 20 teeth each. Group 1 (control group), were irrigated with 5 ml of 2....

BACKGROUND The aim of the study was to evaluate the antimicrobial activity of the-potassium-titanyl-phosphate--the KTP laser and ozone in of primary root canals. MATERIALS AND METHODS Sixty primary incisor teeth were selected. The specimens were inoculated with 10 mL Enterococcus faecalis (E. faecalis). Groups: The KTP laser (1,5 W); gaseous ozone (150 s); sodium hypochlorite (NaOCl); saline ...

INTRODUCTION The combination of sodium hypochlorite (NaOCl) and chlorhexidine (CHX) results in the formation of a precipitate. In a previous study, we demonstrated the formation of 4-chloraniline (PCA) in the precipitate in an amount directly related to the concentration of NaOCl used. AIMS AND METHODS The aim of the present study was to use a diazotization technique to confirm the presence o...

Aim. The purpose of this in vitro study was to assess the antimicrobial efficacy of Biopure MTAD against E. faecalis in contaminated root canals. Materials and Methods. Forty-two single rooted extracted human teeth were inoculated with E. faecalis and incubated for four weeks. The samples were divided in two control and five experimental groups irrigated with 1.5% sodium hypochlorite solution (...
