background and aim: bacterial elimination from root canal system is one of the aims in endodontic treatments, so the addition of antibiotics to sealers can increase their antimicrobial efficacy, as in this study we are determining the in-vitro antimicrobial effect of ah26 and ah plus sealers mixed with amoxicillin, triple antibiotic pastes and nanosilver on enterococcus faecalis. materials and ...

introduction: the aim of this in vitro study was to evaluate the setting time, flow, film thickness, solubility, radiopacity and characterization analysis of three epoxy resin based sealers including two experimental sealers and ah-26. methods and materials: five samples of each material were evaluated for setting time, flow, film thickness, solubility and radiopacity according to iso 6876 stan...

Aim: This study was designed to investigate the effect of different final irrigation protocols on apical sealing ability bioceramic and epoxy resin-based sealers.
 Materials methods: Thirty human single-rooted mandibular premolars were instrumented using ProTaper Next rotary files. Teeth randomly divided into three groups according regimen; Group I: 5 ml 0.2% CNPs/3 min, II: 2.5 CNPs/1.5 m...

The aim of this study was the evaluation of the long term results in the clinical applicability of two root canal sealers, Sealapex Xpress Kerr Endodontics (non-eugenol, calcium hydroxide polymeric root canal sealant) and AH Plus Jet Dentsply Maillefer (epoxy resin-based sealant). 225 teeth of 159 patients included in this study, were endodontic treated and filled with the previously mentioned ...

Sealers are used to enhance concrete durability through their ability to prevent moisture penetration and chloride intrusion, consequently improving the freeze-thaw performance of the concrete and preventing corrosion of the steel reinforcement, respectively. This paper summarizes three years of comprehensive field and laboratory investigations which were undertaken at the University of Manitob...

To study the adhesion of epoxy resin based endodontic sealers by determining the tensile bond strength and evaluating the effect of smear layer removal on the adhesion of the endodontic sealers. Root canals of freshly extracted mandibular first premolar teeth with single root canal, were instrumented by using rotary instrument The roots were prepared for adhesion by splitting them and embedding...

Aim of the study was to evaluate cytotoxicity of five root canal sealers at different intervals of time on HEK-293 (human embryonic kidney epithelial cells) and Vero cells (African green monkey kidney epithelial cells). Endomethasone N, EndoREZ, Acroseal, RoekoSeal and AH Plus were mixed according to manufacturer’s instructions. MTT assay was used to evaluate cytotoxicity of freshly mixed and s...

Confocal laser scanning microscopy can be used in laboratory research to obtain a series of optical XY images through the thickness of the dentin of endodontically treated teeth. With this information the study of the resin/dentin interface of root canal fillings is possible. In comparison to SEM, confocal microscopy has the advantage of providing accurate information and a simple method to det...

INTRODUCTION The aim of this study was to evaluate the cytotoxicity of a new nano zinc-oxide eugenol (NZOE) sealer in comparison with AH-26 and Pulpdent root canal sealers. METHODS AND MATERIALS The L929 mouse fibroblast cells were cultivated and incubated for 24, 48 or 72 h with different dilutions (1/1, 1/2, 1/4, 1/8, 1/16 and 1/32) of culture media previously exposed to either of the test ...

The aim of the present investigation was to evaluate the ability of four root canal sealers against the more resistive Enterococcus faecalis. E faecalis is a common pathogen which is a causative agent of oral cavities. The bacteriostatic effect was studied against the test organism with AH plus, Endorez, Metaplex and Grossmans sealer in 96 well titre plate. After different settling time (20 min...
