OBJECTIVES The purpose of this in vitro study was to evaluate gaps or voids occurring in roots filled with three different sealers. METHODS Thirty extracted human single-rooted teeth were decoronated, instrumented using NiTi rotary instruments, divided into three groups (n=10 per group) and obturated with one of the following: Epiphany with Resilon, MetaSEAL with gutta-percha or AH Plus with ...

objective: root canal obturation is an important step in endodontic therapy aiming at achieving a complete three-dimensional seal of the canal and preventing microleakage, reentry or growth of microorganisms in the root canal system. several techniques and materials are available for root canal filling. achieving an apical seal is among the most important characteristics of filling materials. t...

introduction: the success of endodontic retreatment is related to the complete removal of the obturation material from the root canal system. the aim of this study was to evaluate the efficacy of mtwo r and protaper retreatment files in removing the resilon/epiphany system with or without chloroform during retreatment. materials and methods: sixty distal roots of first mandibular molars were pr...

AIM The aim of this study was to evaluate the fracture strength (FS) of bovine incisors with simulated incomplete rhizogenesis (IR) after different intraradicular treatments. MATERIALS AND METHODS Incomplete rhizogenesis was simulated by sectioning the crowns and roots of 40 bovine incisors. Root canal preparation was performed and the samples divided into 4 groups (n = 10): GI-negative contr...

cytotoxic effects of obturation materials were tested in presence and absence of endotoxin on human monocytes in vitro.human monocytes from thp-1 cell line were cultured. three millimeters from the tip of each resilon and gutta percha points were cut and directly placed at the bottom of the culture wells. cultured cells were exposed to gutta percha (groups g1 and g2) and resilon (r1 and r2). te...

OBJECTIVE To analyze a new endodontic sealer material commercially known as Resilon and to describe in detail the experimental techniques employed that lead to the identification of the composite material. METHODS An extensive structural, thermal, and physical characterization was used to identify a new endodontic sealer material using the following techniques: Fourier transform infrared (FTI...

This study evaluated the effectiveness of 3 solvents (Citrol orange oil, Eucalyptol and Tetrachloroethylene) and 2 associations of solvents (Citrol orange oil+Tetrachloroethylene and Eucalyptol+Tetrachloroethylene) on 3 types of gutta-percha (conventional, thermoplastic and EndoREZ) and Resilon. Ten discs (10 mm diameter x 1 mm thick) from each material were prepared using standard metallic mol...

introduction: adequate root canal seal following retreatment is essential for a successful outcome. resilon/epiphany (r/e) obturation system has been introduced as a substitute for conventional gutta-percha/sealer method. this in vitro study compared the amount of apical microleakage of r/e with gutta-percha/ah26 (gp/ah26) sealer as secondary root canal filling following retreatment in human te...
