INTRODUCTION Microleakage can result in failure of endodontic treatment. An important characteristic of endodontic sealer is sealing ability. The aim of this experimental study was to compare the apical leakage of teeth obturated with gutta-percha and three different sealers (resin- and zinc oxide eugenol-based) with/without smear layer (SL). MATERIALS AND METHODS In this study, 100 single-rooted teeth were used after cutting off their crowns. Cleaning and shaping was carried out with step… CONTINUE READING
