OBJECTIVES: This study aimed to establish a method for measuring the cariogenic potential of foods with high reproducibility in vitro. METHODS: Streptococcus mutans (S. mutans) was incubated in test foods with radioisotope polyacrylamide hydroxyapatite (PAHA) for 150min at 37°C. Then, the amount of radioisotope (32)P released from PAHA was measured using a liquid scintillation counter and scanning electron microscopy (SEM). RESULTS: The radioisotope PAHA discs that were soaked in 10% sucrose solutions had a high cariogenic potential and showed a remarkably demineralized surface (p<0.05). The radioisotope PAHA disc that was incubated with snacks that had a high cariogenic potential showed a remarkably demineralized surface via SEM. Candy had a relatively high cariogenic potential, whereas xylitol gum had a relatively low potential. CONCLUSIONS: The cariogenicity of snacks can easily be evaluated by measuring the amount of (32)P released from radioisotope PAHA discs.
