Abstract

Aim: To compare the push out bond strength and adhesive pattern of a bioactive glass (BG) based root canal sealer with CeraSeal® Bioceramic sealer. Materials and Methods: Sixteen extracted single-root human canine teeth were prepared using Protaper Next rotary files. During instrumentation, 2.5% NaOCl was used for irrigation to eliminate all debris and 17% EDTA as the last irrigant to eliminate the smear layer. The canals were dried using paper points. Sixteen samples were divided equally into two test groups, and one of the pre-selected root canal sealers was applied to obturate the samples using the cold lateral compaction (CLC) technique. The samples, which represent the middle third of root canals, were sectioned horizontally between 5 and 7 mm from the apex. The disc measured 1±0.1 mm in width. Both the adhesive pattern analysis and the push-out test were performed.
Results: The results of the two groups were compared by using Independent t test which showed that the BG based sealer showed insignificant higher mean push-out bond strength (PBS) compared to CeraSeal as (P=0.18).
Conclusion: Our research concluded that the prepared BG based sealer showed relatively comparable bond strength values and adhesive pattern with CeraSeal Bioceramic sealer when used in CLC technique.
