Zinc oxide nano-particles as sealer in endodontics and its sealing ability.

Aims: The aim of this study was to evaluate the sealing ability of new experimental nano-ZOE-based sealer.

Settings And Design: Three types of nano-ZOE-based sealer (calcined at different temperatures of 500, 600 and 700°C) with two other commercially available sealers (AH26 and micro-sized zinc oxide eugenol sealer) were used.

Materials And Methods: Zinc oxide nano-particles were synthesized by a modified sol-gel method.
