ABSTRACT
The antimicrobial activity of four different dental gel formulas was evaluated on theree microorganisms associated with cariogenesis Streptococcus mutans, Lactobacillus casei and Actinomyces viscosus. The preliminary antimicrobial activity evaluation was performed using an agar diffusion method. In addition, the formulas were challenged using each microorganism with subsequent determinations of survivors at time intervals of 1, 5, 10, 20 and 30 minutes. The decimal reduction time (D-value) calculated from the obtained curves (logCFU/mL vs. time) was employed for the antimicrobial activity comparison of the formulas. The selected method for survivor enumeration was validated according to official compendia...
