The aim of the present study was to evaluate influence ultrasonic activation (UA) on setting time and flow four endodontic sealers: AH Plus (AH), Sealer (SP), MTA Fillapex (MTAF), BioRoot RCS (BIO). Properties were evaluated as required by ANSI/ADA Specification N° 57 (2008); only size specimens modified. UA applied using a smooth tapered tip coupled piezoelectric device (30% power) freshly mix...

The aim of this study was to evaluate periapical repair after root canal filling with different endodontic sealers. Sixty-four root canals from dog s teeth were filled, divided into 4 groups (n=16). Root canals were instrumented with K-type files and irrigated with 1% sodium hypochlorite solution. Root canals were filled in the same session by active lateral condensation of the cones and sealer...

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: Tw...

This study evaluated in vitro the cytotoxicity of four root canal sealers (Topseal, EndoRez, TubliSeal and Kerr Pulp Canal Sealer E.W.T.) and their effects on reactive oxygen/nitrogen intermediate induction by mouse peritoneal macrophages. Thioglycollate-induced cells were obtained from Swiss mice by peritoneal lavage with 5 mL 10 mM phosphate-buffered saline, washed twice and resuspended (10(6...

Aim. To evaluate the antibacterial activity of four endodontic sealers on Enterococcus faecalis by a direct contact test. Material and Methods. Enterococcus faecalis was used as a test organism. Direct contact test which is based on measuring the effect of close contact between test bacteria and tested material on the kinetics of bacterial growth was performed to overcome the disadvantages of a...

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 ...

Objective – To evaluate in vitro adhesion of endodontic sealers Rickert, AH Plus, Sealapex and Epiphany to dentin previously conditioned with one of two different chemical solutions. Methods – A total of 80 specimens were made up with bovine incisive teeth that were prepared by cutting predetermined sections and wearing them, producing standard experimental samples. Forty samples were treated w...

INTRODUCTION The main goal of endodontic treatment is elimination of bacteria and their by-products from infected root canals. This study compared the antibacterial effect of two different sealers, AH 26 and MTA Fillapex, on 4 microorganisms 24, 48 and 72 h and 7 days after mixing. METHODS AND MATERIALS The microorganisms used in this study consisted of Lactobacillus acidophilus (ATCC 4356), ...
