Samples were tested for microleakage using silver nitrate and infiltration was classified in 5 levels. The differences in microleakage were statistically evaluated with significance set at p<0.05.</p> <p><strong>Results</strong> In the margin located in the enamel, group 1 showed an average of 0 microleakage, group 2 an average of 0.2 and group 3 an average of 0.1. In the margin located in the dentin, group 1 showed an average score of 1.1, group 2 of 2.15 and group 3 of 1.25. No statistically significant difference was found in the enamel.</p> <p><strong>Conclusion</strong> The combination of adhesive G2-Bond Universal and Optibond FL showed the highest sealing ability both in margins located in the enamel and margins located in the dentin. The adhesive interface in the enamel produced a very good seal, while the adhesive interface in the dentin showed varying degrees of microleakage in all groups.</p>}, number={3}, journal={Journal of Osseointegration}, author={Ferrari Cagidiaco, E. and Karafili, D. and Verniani, G. and Zucca, G. and Ferrari, M.}, year={2021}, month={Sep.}, pages={115–120} }
