Effect of ellagic acid on S. mutans biofilm formation (A), cell growth (B), and GTase activity (C). At a concentration of 0.25 mM, the impact of ellagic acid on GTase activity was examined (B). The amount of biofilm was represented by crystal violet (CV) absorbance at 595 nm. Six (A and C) and three (B) distinct experiments were used to calculate the values. A and B were analyzed statistically using Tukey’s test (A and B) or a paired t-test (C). Values that differ from the control with a 95% confidence level are marked with an asterisk on top of the symbols or bars
