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

Abstract

<br><b>Aim:</b> The aim of the study is to compare the push-out bond strength of bioceramic and epoxy sealers after using various final irrigants.<br><b>Materials and Methods:</b> Hundred single-rooted teeth were divided into two groups (<i>n</i> = 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 (<i>n</i> = 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.<br><b>Statistical Analysis:</b> The data were statistically analyzed using two-way ANOVA and independent Student's <i>t</i>-test.<br><b>Results:</b> 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 (<i>P</i> < 0.05).<br><b>Conclusion:</b> 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.<br>
