The need for an antimicrobial penetrant-sealer became evident as the problem of flaking paint in food processing plants was explored. Flaking paint can fall into product, a situation which cannot be tolerated. The standards, set by the packing industry, for purity, freshness, and attractiveness preclude any foreign matter in product. Flaking paint as a problem has been with us since paint was f...

The purpose of this study was to compare the surface pH level of four different type sealers after mixing at various time intervals in vitro. After cleaning and shaping root canals in 50 recently extracted, single-rooted human teeth, they were divided into six groups. Each of four groups was obturated with Apexit, N2, Sealapex, and Grossman sealers. The remaining groups served as controls. In g...

Introduction: Growth and proliferation of the remaining microorganisms within the root canals may destroy the surrounding tissue of the root and leads to periapical lesion. Consequently, the complete elimination of microorganisms from the root canal is a n important goal of endodontic therapy. Endodontic sealers do not provide complete seal in root canal system, and micro spaces have always rem...

The concrete has been and at the same time will be most used construction material worldwide. It is exposed to various physical chemical degradation processes that deteriorate its properties shorten service life in applications. As of detrimental effects on come from ambient environment, quality surface plays a key role overall performance. should resistant abrasion, free microcracks open pores...

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...
