the aim of this study was to compare the apical seal of curved canals obturated with resilon/epiphany with gutta-percha/ah plus.thirty-four extracted human mandibular molars with 25-40 degree canal curvature of the mesial root were selected for this study. after preparation, the mesiobuccal canals were obturated with gutta-percha and ah- plus sealer (group g) or resilon and epiphany sealer (gro...

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...

BACKGROUND AND OBJECTIVE To date, many different materials have been proposed for root canal fillings, but gutta-percha (used with various types of sealers) has remained the material of choice for over a century. A new root canal obturation system, the Epiphany endodontic obturation system, has been developed to replace gutta-percha and traditional sealers for root canal obturation. The purpose...

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...

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 ...
