After 2 hours of incubation with log phase Streptococcus mutans cells, the materials GC Fuji I and 3M ESPE Ketac Cem Easymix showed a significantly reduced number of CFUs (P < 0.05) when compared pairwise to the negative control.
Upon data fitting, though the logistic and the Gompertz curves were not congruent in the lag phase region as well as in the transition region of the log phase to stationary phase, the chi square validation results show that the overflow of error occurred in the lag phase compared to the transition region of log to stationary phase.
At the late log phase, the cultures were diluted (1:50) into the same medium without glucose, and the growth continued for 24 hr.
