Abstract

Objective: In this study, the contents of organic acids and sugars which can cause demineralization of tooth were measured in sports drinks, and predict the cariogenic potential of sports drinks, high-caffeined carbonated beverages.
Methods: The organic acids were determined by polar-endcapped reversed phase chromatography and UV 210 detection, and sugars were determined by anion-exchange chromatography with pulsed amperometric detection. After drinking a sports drinks, the salivary concentration of citric acid were determined according to the elapse time.
Results: The total organic acid concentration range of sports drinks were 0.61-2.22 g/L, and total sugar concentration range were 20.09-139.87 g/L. After drinking sports drinks, the citric acid was decreased to 1 g/L at 5 min after drinking, and dis-appeared at 15 min after drinking.
Conclusion: The ingredient of sports drinks can cause hardness loss of enamel. It is considered important to caution on the danger of sports drinks and to care oral health after sports drinks intake.
