Coronal sealing ability of a new root canal filling material (original) (raw)

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 of this study was to evaluate the coronal sealing ability of the new endodontic obturation system. Seventy-two maxillary and mandibular single-rooted human teeth extracted for periodontal reasons were used. The root canals were instrumented using the step-back technique and were irrigated with 5.25% sodium hypochlorite. The smear layer was removed by washing in 10 mL of 17% ethylenediamine tetra-acetic acid (EDTA). The specimens were randomly divided into 3 groups (group 1 to be filled with gutta-percha and AH 26 sealer, group 2 with gutta-percha and AH plus sealer, and group 3 with Epiphany self-etch sealer and Resi...
