Comparative evaluation of push-out bond strength of bioceramic and epoxy sealers after using various final irrigants: An in vitro study.

Aim: The aim of the study is to compare the push-out bond strength of bioceramic and epoxy sealers after using various final irrigants.

Materials and Methods: Hundred single-rooted teeth were divided into two groups ( n = 50) according to the sealer used: Group A: Bio C (bioceramic sealer), Group B: Dia-Proseal (epoxy sealer). Each group was subdivided into five subgroups ( n = 10) according to the final irrigation protocol: Group A1 and B1 - 5% glycolic acid (GA), Group A2 and B2 - 17% GA, Group A3 and B3 - 0.2% chitosan, Group A4 and B4 - 17% ethylenediaminetetraacetic acid, and Group A5 and B5 - 0.9% saline. Samples were obturated in combination with one of the mentioned sealers and were allowed to set for 1 week. Two horizontal slices were obtained from each sample and subjected to push-out test.

Statistical Analysis: The data were statistically analyzed using two-way ANOVA and independent Student's t -test.

Results: Both the sealers exhibited higher push-out bond strength after treatment with GA with no significant difference between 5% and 17% GA. Bio C sealer with GA as final irrigant showed higher bond strength than Dia-Proseal ( P < 0.05).

Conclusion: The push-out bond strength of the sealer was significantly affected by the final irrigation solution used. The highest push-out bond strength was seen with Bio C sealer after treatment with GA with no significant difference between 5% and 17% GA.
