Objectives: The aim of this study was to compare the microleakage between resin-based (AH plus®) and bioceramic-based (EndoSequence BC Sealer®) root canal sealers using the fluid filtration technique.
Materials and methods: Seventy extracted human mandibular premolars resected 12 mm. from the apex were instrumented to size 50/.04 using the Mtwo rotary system. They were then randomly divided into 3 experimental groups based on obturation technique and sealer (G1: AH plus obturated by warm vertical compaction, G2: EndoSequence BC Sealer obturated by warm vertical compaction, and G3: EndoSequence BC Sealer obturated by single cone technique), and 2 control groups. After their completed obturations, the samples were stored in containers of 100 percent relative humidity for 48 hours. Microleakage was assessed using fluid filtration method, employing a pressure equivalent to 0.03 atm through a 1-mm diameter capillary tube. Statistical analysis was performed using the Kruskal-Wallis test followed by Dunn’s multiple comparison test at the 0.05 significance level.
Results: The rate of fluid leakage between the two EndoSequence BC Sealer groups (EndoSequence BC Sealer by single cone technique and EndoSequence BC Sealer by warm vertical compaction) were significantly different (p < 0.05). However, no statistically significant difference was found between the AH plus group and both the EndoSequence BC Sealer groups.
