Cytotoxicity evaluation of Activ GP and Resilon sealers in vitro
Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology, and Endodontology, 2009This study is to evaluate the cytotoxicity of Activ GP and RealSeal sealers in a cell culture system in vitro, and to compare them with traditional AH 26 and Kerr sealers.Samples of 0.5 mg freshly mixed or set RealSeal, Activ GP, AH 26, and Kerr sealers were eluted with 200, 400, 800, and 1,200 microL cell culture medium for 24 and 72 hours. L929 cells

Cytotoxicity evaluation of Active GP and Resilon cones in vitro
Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology, and Endodontology, 2008This study was done to evaluate the cytotoxicity of Activ GP and Resilon cones in an in vitro cell culture system.Gutta-percha (GP), Activ GP, and Resilon cones were tested in this study. L929 cells were seeded into 96-well plates at 3 x 10(4) cells/well. In one set of experiments, 2-mm segments cut from the tip of GP and Resilon cones were placed into

Spreader Penetration During Lateral Compaction of Resilon and Gutta-Percha
Journal of Endodontics, 2006Resilon, a thermoplastic, polyester polymer-based filling material, is a new material used for sealing root canals after chemomechanical preparation. The purpose of this in vitro study was to compare nickel-titanium (NiTi) spreader penetration in root canals having a .04 taper preparation using .02 and .04 tapered master gutta-percha cones and .02 and .

An in Vitro Assessment of the Sealing Ability of Resilon/Epiphany Using Fluid Filtration
Journal of Endodontics, 2006The aim of this in vitro study was to compare the sealing ability of Resilon/Epiphany to gutta-percha and Roth or AH Plus sealers. Leakage of the obturated roots was measured using the fluid filtration technique. There were eight groups of 12 teeth each. Group 1: obturated with Resilon/Epiphany; group 2: obturated with gutta-percha/Roth, allowed to set

A Comparison of Gutta-Percha and Resilon in the Obturation of Lateral Grooves and Depressions
Journal of Endodontics, 2007The purpose of this study was to compare the flow of gutta-percha and Resilon (RealSeal; SybronEndo, Orange, CA) into lateral grooves and depressions in the apical 7 mm of a root canal by using warm vertical compaction. A split-tooth model was constructed with lateral grooves and depressions prepared at 1, 3, 5, and 7 mm from working length (WL ...

Setting Times of Resilon and Other Sealers in Aerobic and Anaerobic Environments
Journal of Endodontics, 2006Eleven sealers, including Resilon sealer, were mixed according to manufacturer's instructions. Setting times were determined in both aerobic and anaerobic environments. Two samples of each sealer were mixed and placed in the following conditions: (a) uncovered in an aerobic incubator; (b) covered with a glass cover-slip in the aerobic incubator; (c ...

An In Vitro Comparison of the Intraradicular Dentin Bond Strength of Resilon and Gutta-Percha
Journal of Endodontics, 2006The purpose of this study was to compare the micropush-out bond strength of Resilon to that of gutta-percha. Extracted human anterior teeth were used for evaluation. The crowns were removed and the root canals were instrumented with Gates Glidden drills and 0.06 Profile rotary files.

Contamination of gutta-percha and Resilon cones taken directly from the manufacturer
Clinical Oral Investigations, 2009Any substance and material placed in the root canal either temporarily or definitively must be free of microbial contamination. The purpose of the present study was to evaluate the percentage of contamination of Resilon cones, a polycaprolactone-based material, and seven different brands of gutta-percha cones available in the specialized market.

Adhesion of Self-adhesive Root Canal Sealers on Gutta-Percha and Resilon
Journal of Endodontics, 2010The aim of this study was to evaluate the bond strength of different adhesive sealers on Resilon and gutta-percha.Pellets of gutta-percha and Resilon were embedded into test tubes. Small eyelets were attached to those surfaces with a 0.5-mm film of different root canal sealers. Real Seal, Real Seal SE, Hybrid Root Seal (also known as Meta Seal), and AH
