Objective: Although several sealers have been developed, the zinc oxide eugenol (ZOE) sealer is still used in many private dental clinics. This study aimed to compare the biocompatibility and remineralizing capacity οf ZOE sealer with the addition of nanohydroxyapatite-tyrosine amino acid.
Methods: This study was conducted on Twenty rabbits.
Objective: This study evaluated the apical sealing ability of various types of sealers (Sure-Seal Root, AH Plus, and GuttaFlow2) at different levels of remaining gutta percha after post space preparation at two time intervals (1 day and 1 week after obturation).
Materials And Methods: One hundred and two single canal mandibular premolars were decoronated at the cement-enamel junction and biomechanically prepared. Twelve samples served as negative and positive controls ( = 6).
