  • Streptococcus mutans is known as a strong cariogenic bacterium and produces dental caries. This study was carried out to develop anticariogenic agents from Callistemon citrinus. Crude extracts and thier various solvent fractions of the plant extracts were tested for the antibacterial activity against S. mutans. The anticariogenic activity was evaluated with by paper disc diffusion method and minimal inhibition concentration (MIC). The extract from the fruit and its hexane fraction showed a strong inhibitory effect on the growth of S. mutans and the MICs were 31.2 and $3.9{\mu}g/m{\ell}$, respectively.
