Figure 1. Metabolic activity of S. mutans biofilms adhered to Transbond XT, Transbond XT+1%MAE-HB, Transbond XT+3%MAE-HB, and Transbond XT+5%MAE-HB.

Metabolic activity was measured via the CCK-8 assay at 1d and after aging for 6 months. In each plot, values (mean ± standard deviation; n = 6) with dissimilar letters are significantly different (P < 0.05).
