In vitro analysis of the sealing ability of different root canal sealers under thermo-mechanical stress.

The ability to create a proper seal by testing three root canal sealers under conditions that replicated thermal and mechanical stresses is of interest. A total of sixty human single-rooted teeth received epoxy resin-based and calcium silicate-based and bioceramic-based sealers before thermocycling and mechanical loading procedures. Microleakage examinations demonstrated that bioceramic sealer allowed the least dye penetration at 0.45 ± 0.12 mm while calcium silicate sealer permitted 0.71 ± 0.18 mm penetration and epoxy resin sealer ended with 1.02 ± 0.21 mm penetration. The statistical analysis using a One-way ANOVA method established significant differences at a p value less than 0.05. The use of bioceramic sealers leads to high-quality apical barriers which enhances continued endodontic treatment success.
