Figure 4.

Results of the microbiological behavior of the tested materials in terms of bacterial adherence (A) and biofilm formation (B) by S. mutans. A highly significant decrease in both adherence and biofilm formation can be observed on materials cured for an extended time (80 s). Interestingly, differences in adherence and biofilm formation between materials disappeared after extended curing time (80 s). Different superscript letters indicate significant differences between materials (Tukey’s test, p < 0.05) for a given element.
