Figure 4

Antibiofilm activity of oleoresin and (–)-polyalthic acid as demonstrated by optical density (A570) and number of microorganisms (Log10 CFU mL−1) against bacteria that cause endodontic infections. The experiments were performed in triplicate and statistical significance was examined by Student's t-test. Results are indicated as means ± SDs. *Significantly different from the negative control group (P < 0.05). Filled bars correspond to MICB50 concentration.
