The purpose of this study was to develop a practical caries activity test to be used for
selecting the children of high caries activity. For simultaneous culture of Streptococcus
mutans and Lactobacillus, new culture medium was prepared. 30% sucrose liquid
medium was made and lactic acid was added to lower the pH of the medium to 5.4. 138
preschool children were examined for dmfs index. The plaque sample was obtained from
buccal surfaces of upper posterior teeth. through the 96hours of incubation period, acid
production of both Streptococcus mutans and Lactobacillus was evaluated by the color
change of liquid medium every 24hour, and pH-decline velocity was measured after
72hours and 96hours. dmfs index was correlated significantly with the acid production
score and the velocity of pH decline. Acidic high sucrose liquid medium ana be used as
culture medium for cariogenic bacteria.
