The effect of combinations of 8 antimicrobial agents on the growth of Streptococcus mutans and Streptococcus sobrinus was investigated with the minimum inhibitory concentration and fractional inhibitory concentration(FIC) and IFIC index. According to the IFIC values by The American Society for Microbiology and Berenbaum, Approximately 34% and 82% of the combinations were synergistic respectively_ Partial synergy described by Isenberg was also observed in the half of the combinations.
There was a tendency for additive antimicrobial effect against cariogenic bacteria though the test results showed difference according to the applied values. It may be beneficial to use combined antimicrobial agents that have various activities against an ecosystem and metabolism of bacteria than using individual agents.
