Abstract

Aim:  The main objective of this study was to assess the coronal microleakage using polymicrobial marker when the access cavities were restored with GC Fuji IX, Filtek TM Z350 XT, Filtek TM Z350 XT and Ketac TM N100.  Materials and Methodology: Access opening of single rooted teeth were done and clean and shaped using step down method. All teeth were sectioned horizontally to 4mm thickness and were randomly grouped to restore with their respective restorative materials (nano-composite, conventional composite, nano-glass-inomer cement and conventional glass inomer cement). All the samples were artificially aged by thermocycling and were placed in their respective ependroff tubes over which bacteria inoculated brain heart infusion broth was placed. These tubes were placed in sterile bottles containing sterile broth and observed for turbidity.  Results: Kruskal-Wallis one way ANOVA test and Chi-square test using SPSS 20.0 version was used to statistically analyze the sealing ability of the four restorative materials.  Conclusion: There was no significant difference among the four groups. Nanocomposite (Filtek TM Z350 XT) showed better sealing ability than other three groups. Least sealing ability was seen with group restored with conventional glass ionomer cement.
