Context Human dentin powder (HD), bovine serum albumin (BSA) and endotoxin (LPS) may affect the antimicrobial activity of irrigating solutions. Aim To evaluate the inhibitory effect of HD powder, BSA, and LPS on the antibacterial activity of 0.5%, 1%, 2.5%, and 5% sodium hypochlorite (NaOCl), 2% chlorhexidine (CHX) gel, BioPure mixture of tetracycline, citric acid, and detergent (MTAD), and Q...
INTRODUCTION The aim of this study was to compare the smear layer removal efficacies of 3% sodium hypochlorite (NaOCl), 17% Ethylenediaminetetraacetic acid (EDTA), SmearClear and BioPure MTAD using a common irrigation protocol. MATERIALS AND METHODS Fifty freshly extracted human single rooted maxillary and mandibular teeth were prepared by a ProTaper rotary system up to an apical preparation ...
BACKGROUND AND AIMS The aim of the present study was to compare 1.3% sodium hypochlorite (NaOCl) in MTAD (mixture of tetracycline isomer, acid, and detergent) for the removal of the smear layer and induction of canal erosion. MATERIALS AND METHODS 38 maxillary incisors were divided in three experimental groups of 10 and two positive and negative control groups of each 4 teeth, and prepared us...
STATEMENT OF THE PROBLEM Root canal therapy should not simply be the extirpation of the pulp and widening of the canal. But one should also focus on how to completely remove the loosely-attached smear layer because it has adverse effects on the final outcome of the treatment. PURPOSE This study compared the efficacy of Etidronic acid, SmearClear and MTAD to remove the smear layer created duri...
Objectives: To evaluate the combined e"ect of a mixture of tetracycline, acid, and detergent (MTAD) and Nisin against Enterococcus faecalis (E. faecalis) and Actinomyces viscosus (A. viscosus) bio!lms. Methods: #is study was conducted between June and December 2013 in collaboration with Dental Caries Research Chair, College of Dentistry, King Saud University, Riyadh, Saudi Arabia. Single-specie...
The objective of this research was to assess the effects several irrigation solutions (ISOLs) on two major (P and Ca) some minor (Fe, Zn, Sr) elements multi-root canals radicular dentin in upper premolar teeth using X-ray fluorescence analysis (XRF). Powder fifty specimens were prepared divided into five groups based treatments with different single combined ISOLs. These were: G1-distilled wate...
BACKGROUND AND OBJECTIVES Evolution in understanding the poly-microbial environment of both endodontic infections and that of failed root canal treatments has been debatable over the years. The present study was designed to compare and analyze the effect of various root canal irrigation solutions on certain endodontic pathogens in vitro. MATERIALS AND METHODS To analyze in vitro the zone of i...
The aim of this study is to compare the surface tension of four common endodontic irrigants: Moltendo EDTA 17%, Cetrexidin, Smear Clear, Sodium hypochlorite 5.25%, with the surface tension of MTAD and Tetraclean. Freshly produced MilliQ water was used as a reference. All measurements were performed following the Wilhelmy plate technique, using a Cahn DCA-322 Dynamic Contact Angle Analyzer at th...
AIM This study was conducted to evaluate the antimicrobial activity of 5.25% sodium hypochlorite (NaOCl), 2% chlorhexidine (CHX) and BioPure MTAD when used as a fnal rinse against Enterococcus faecalis. MATERIALS AND METHODS Sixty single-rooted premolars were biomechanically prepared, inoculated with E. faecalis and divided into various groups. These were then irrigated with the test irrigant...
OBJECTIVE The objective of this study was to compare the ex-vivo sealing ability of Resilon/new Epiphany (SE) sealer to that of gutta-percha/AH-Plus following smear layer removal with EDTA or MTAD. STUDY DESIGN One hundred extracted single-rooted human teeth were divided into 4 experimental groups and 2 positive and negative control groups. EDTA was used in groups 1 and 2. In groups 3 and 4 M...
