Abstract
Objective: The purpose of this study is to measure the amounts of cariogenic components in saliva after eating sugars and to investigate the variations and restoration of the salivary components as time elapsed.
Methods: The saliva was collected at 0, 1, 2, 5, 10, 15, 20, and 30 minutes after eating 10% sucrose solution, and analyzed the cariogenic compounds. The sugars (mono- and di-saccharide) was analyzed anion-exchange chromatography with pulsed amperometric detection method, and organic acids (lactic acid, acetic acid, and formic acid) was analyzed with ion chromatography with suppressed conductivity detector method.
Results: Sucrose was detected immediately after eating, and rapidly decreased as time passed. Monosaccharides generated from sucrose decomposition were also found in saliva. The clearance of disaccharide was faster than that of monosaccharide. Organic acids (lactic acid, acetic acid, and formic acid) generated from sugar metabolism were also detected, and the lower organic acid with lower molecule were more slowly generated and disappeared. The concentration of lactic acid was peaked at 2 minutes after eating sugars.
Conclusion: To prevent the teeth from cariogenic acids, mouth should be cleansed as soon as possible after eating foods, because the organic acids were generated in short times within a few minutes.
