In Vitro Microleakage Evaluation of Bioceramic and Zinc-Eugenol Sealers with Two Obturation Techniques

Aim of the study is to compare quality apical seal offered by a zinc-eugenol and tricalcium-silicate-based sealer, both used with single-cone or continuous wave condensation technique. Forty central incisors were divided into four groups (n = 10), according two sealers obturation techniques under investigation, their outer surface was isolated nail varnish. After endodontic treatment, samples immersed in methylene blue dye for 72 h, then included self-curing resin sectioned longitudinally expose canal third. The depth penetration measured each group. Mean values compared two-way-ANOVA test. Multiple comparisons performed Tukey level significance set at 0.05 all tests. technique led reduced microleakage. Moreover, tricalcium-silicate sealer. In terms microleakage, warm seems promising even when combined bioceramic
