Evaluation of Apical Leakage After Root Canal Obturation with Glass Ionomer, Resin, and Zinc Oxide Eugenol Sealers Combined with Thermafil.

BACKGROUND A hermetic seal at the apical terminus is required for healthy periradicular tissue. Root canal obturation sealers that are used in endodontics are based on zinc oxide eugenol, calcium hydroxide, resins, glass ionomers, silicone, or bioceramics, but no optimal sealer material has been identified to date. Therefore, the aim of this in vitro study was to evaluate apical leakage after crown-down preparation and root canal obturation with Endomethasone N, glass ionomer cement, and EndoRez sealers.

An In Vitro Comparative Evaluation of Apical Leakage Using Different Root Canal Sealers.

BACKGROUND Successful endodontic therapy requires a fluid-tight apical seal. The aim of this in vitro study was to evaluate and compare the apical sealing ability of 3 root canal sealers: Apexit Plus, AH Plus, and Resilon/Epiphany sealers. MATERIAL AND METHODS Samples of 152 single-rooted teeth were divided into 2 test groups, and each group was divided into 3 subgroups based on the preparation and obturation technique.
