Abstract

This in vitro study sought to evaluate the sealing ability of 3 root canal obturator systems after immersion in simulated body fluid for 1 year. The coronal sections of 30 single-rooted teeth were removed at the cementoenamel junction at 12 mm (±1 mm), and roots were instrumented with nickel titanium instruments. Specimens were divided into 3 groups (n = 10) according to the obturation manufacturer-specified system and immersed in simulated body fluid. A digital fluid flow-meter was used to detect the flow rate at 1 week, 1 month, and 12 months after immersion. This study demonstrated that the tested endodontic obturation systems were unable to keep their sealing ability stable during the first year. At 12 months, all root filling systems showed increased flow rates (P <0.0001).
