The purpose of this study was to evaluate the reliability of the method for assessing
cariogenicity of foodstuffs using pH drop by S. mutans. S. mutans was cultured with 8
§¢ of Todd-Hewitt broth for 7 hours. Then, this broth was centrifuged and 7 §¢ of
supernatant was removed and 1 §¢ of bacterial pellet was remained. Each 1 §¢ of 0.1%,
0.5% and 1.0% sucrose solution as the experimental groups and distilled water as a
control group were mixed with these remained bacterial pellet and cultured at 37¡É. The
pH was measured at each 10 minutes for 2 hours.
The caries potential index(CPI) was measured by calculating the width of area below
pH 5.7 line. The reliability of the method was evaluated by comparing coefficients of
variation of CPI.
As the results, with concentration of sucrose solution between 0.1% to 1.0%, the
method assessing CPI using S. Mutans discriminated each CPI of solutions fairly well
and was reliable.
