Effect of gutta-percha cone-mediated ultrasonic activation on the push-out bond strength and dentinal tubule penetration of epoxy resin- and silicate-based root canal sealers: an in vitro study.

ABSTRACT:

Background

Ultrasonic activation may alter the bond strength and intratubular penetration ability of root canal sealers, which are important criteria for the long-term success of root canal treatment. The aim of this study was to compare the effect of mediated ultrasonic activation in the push-out bond strength and intratubular penetration values of epoxy resin- and silicate-based root canal sealers.

Methods

One hundred and sixty human mandibular premolar teeth were used. The teeth were divided into two groups for bond strength and tubular penetration tests and further divided into four subgroups for obturation and ultrasonic activation (n = 20). Chemo-mechanical preparation of the root canals was performed with a Mtwo rotary instrument system accompanied by NaOCl irrigation
