Fig 2. Minimum inhibitory concentrations (black bars) and minimum neutralizing concentrations (white bars) of test dentifrices (TD, FD, SFD1 and SFD2) in Tryptone Soya Broth under aerobic and anaerobic conditions.

Error bars represent standard errors for three biological replicates, each with three technical repeats. Asterisks indicate statistically significant differences (p< 0.05) between MIC and MBC determined using a paired Student’s t-test.
