The antibacterial activity of root canal sealers may contribute to the eradication remaining bacteria in canals following shaping and debridement. aim study is assess antimicrobial effect 3 endodontic sealers: Sealapex™, EndoREZ™ Guttaflow bioseal™ against Enterococcus faecalis. This was a laboratory-based comparative testing three were tested unset 20 minutes after mixing setting. Testing sett...

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 purpose of the present study was to compare the shear bond strength to human dentin of 2 root canal sealers: Sultan U/P (zinc-oxide euge nol) and 2seal (epoxy resin). The dentin specimens were divided randomly into 2 groups (A, B) of 12 specimens each, and etched with 3 ml of EDTA 17% before rinsing with NaOCl 2.5% and distilled water. The 2 sealers were mixed according to the manufacturer ...

AIM The aim of this in vitro study was to evaluate the apical seal obtained with four root canal sealers AH 26, Sealapex, Endoflas FS and AH Plus, with lateral condensation. MATERIALS AND METHODS Sixty root canals were prepared using the step-back technique. The specimens were divided into four experimental groups of 12 teeth and two control groups of 12 teeth. The experimental groups were ob...

introduction the materials used for obturation of root canal system may be extruded through apical foramen into the periapical tissue. therefore, biocompatibility of these materials is very important. the purpose of this study was to evaluate the in vivo biocompatibility of three conventional endodontic sealers: ah26, roth 801, and zoe after their subcutaneous implantation in rats. methods twen...

background & aim: antibacterial effect of the sealers which are used in root canal therapy is a factor which increases the rate of success in root canal therapy. the aim of this study was to compare the antibacterial effect of three sealers (zoe, ah26, dorifill) on two bacterial species, staphylococcus aureuse and streptococcus mutans immediately after mixing and one week after mixing. methods ...

The sealing of the root canal system is of fundamental importance for successful endodontic treatment. To obtain an adequate apical seal, many factors must be considered such as the presence of smear layer and the sealer applied. After canal preparation, this layer must be removed because it prevents close contact between the dentinal walls and the sealing material. The goal of this study was t...

introduction: the purpose of this in vitro study was to evaluate three common gutta-percha solvents’ effectiveness in dissolving three different types of root canal sealers. materials and methods: the solubility of three different root canal sealers (ah plus, apexit plus and endoflas fs) was assessed in xylene, refined orange oil, tetrachloroethylene and distilled water (control). one-hundred t...

This study evaluated comparatively the adhesion of Epiphany and AH Plus endodontic sealers to human root dentin treated with 1% NaOCl and 1% NaOCl+17% EDTA, using the push-out test. Sixty root cylinders obtained from maxillary canines had the canals prepared and were randomly assigned to 3 groups (n=20), according to root dentin treatment: GI - distilled water (control), GII - 1% NaOCl and GIII...

The purpose of this study was to evaluate the influence of coronal leakage on the healing of dogs' periapical tissues after root canal filling, post space preparation and protection or not with a temporary sealer plug. Forty root canals of dogs' teeth were instrumented and filled by the lateral condensation technique with gutta-percha points and Endomethasone or CRCS sealers. After post space p...
