Objective: The study aims to investigate whether the surface sealants applied on the materials in Class V cavities restored using different glass ionomer materials have an effect on the microleakage of the materials. Methods: 120 extracted non-carious human premolar teeth were used in the study. Teeth were randomly divided into three groups of 40 teeth for each and restored with conventional glass-ionomer cement (GIC), resin-modified glass-ionomer cement (RMGIC) and polyacid-modified resin composites (PMRC). Protect-it, LC Varnish and Finishing Gloss surface sealants were applied to these filling materials separately, apart from the control group. The microleakage of occlusal and cervical margin was evaluated separately. The data were statistically analyzed with the Kruskal-Wallis One-Way ANOVA test, and Mann-Whitney U test. Results: According to the results obtained, in the occlusal and cervical margins, there was a statistically significant difference between conventional GIC and RMGIC (P<.05), but there was no statistically significant difference between PMRC and the others. For the conventional GIC, Protect-it and LC Varnish were the most effective surface coating among the tested materials, while the best surface protection was obtained with LC Varnish and Finishing Gloss in the PMRC. The lowest level of leakage at cervical margin was achieved with Protect-it and LC Varnish in conventional GIC and with LC Varnish in the PMRC. Conclusion: In this study, it has been shown that the use of restorative materials with surface protection provides a reduction in the amount of margin leakage and may therefore contribute to the success of the restoration.
