INTRODUCTION Retreatment of endodontically treated teeth is a challenge that requires complete removal of the previous filling material. Several techniques are indicated for this procedure. The present review tries to identify the most efficient method for extirpation of Resilon (RS) root fillings and to compare the speed and efficacy of RS and gutta-percha (GP) root filling removal. METHODS ...

BACKGROUND The key to success of any root canal therapy is adequate obturation of the prepared root canal space. Root canal sealers are not dimensionally stable and might dissolve partially over a period of time. The objective of this in vitro study is to evaluate the push-out bond strength to intraradicular dentin of two endodontic obturation materials. MATERIAL AND METHODS Forty extracted s...

CONTEXT The study assesses the apical sealing ability of two obturating materials (resilon and gutta-percha) with their sealants by means of the dye penetration method using India ink. AIMS To compare the resistance to apical dye penetration between resilon (with Epiphany sealer; Epiphany, Pentron clinical technologies, USA) and gutta-percha (with AH Plus sealer; Dentsply, Maillefer, Germany)...

OBJECTIVE To assess the effects of different final irrigants on the bond strength of bonded root filling materials, Epiphany/Resilon and Epiphany self-etch (SE)/Resilon. MATERIALS AND METHODS The root canals of eighty single-rooted extracted human teeth were prepared. After the smear layer was removed using 17% EDTA, the samples were randomly divided into eight groups. In groups 1 and 2, no a...

OBJECTIVE Eradication of microorganisms present in the root canal system is paramount for the successful outcome of root canal therapy. The purpose of this study was to compare the of doxycycline absorbed from MTAD into root canal dentin after obturation with gutta-percha/AH26 and Resilon/RealSeal at different time intervals. MATERIALS AND METHODS Fifty-one extracted human teeth were instrume...

Background and aims. An ideal root canal filling material should completely seal the entire root canal space and block communication between the root canal system and its surrounding tissues; it should also be nontoxic, noncarcinogenic, non-genotoxic, biocompatible, insoluble in tissue fluids and dimensionally stable. Bonding to dentin is a promising property, which can prevent leakage and impr...

Objective: The era of endodontics has taken a new dimension with the advent of a synthetic, thermoplastic resin filling material, named Resilon. Our in vitro study tested the efficacy of this new obturating system, versus the ageold material Guttapercha. Materials & Methods: Forty five central incisor teeth, extracted due to periodontal reasons, were assigned to two experimental (Resilon and AH...

INTRODUCTION The purpose of this study was to evaluate the sealing ability of gray-colored mineral trioxide aggregate (GMTA), white-colored MTA (WMTA), and Resilon as root filling materials. MATERIALS AND METHODS Sixty-six human maxillary central incisors were used in the present study. In the group A, 20 teeth were filled with GMTA. In the group B, 20 teeth were filled with WMTA and in the g...

a w o 3 bstract leven sealers, including Resilon sealer, were mixed ccording to manufacturer’s instructions. Setting times ere determined in both aerobic and anaerobic envionments. Two samples of each sealer were mixed and laced in the following conditions: (a) uncovered in an erobic incubator; (b) covered with a glass cover-slip in he aerobic incubator; (c) covered with phosphate buffred salin...
