The purpose of this study was to observe the demineralization effects of commercial drinks on bovine enamel. 12 bovine teeth without dental caries were divided into 3 experimental groups (n = 9) and control groups (n = 3). All the samples immersed in beverages maintained by 37oC in incubator respectively. The differences of surface microhardness values(ΔVHN) between before and after 45 hours treatment were 166.97±51.69(in Coca-cola), 116.26±20.81(in Gatorade), 77.89±55.88(in Hite), and 23.44±29.97(in Jeju SamDaSoo). Morphological changes by scanning electron microscope were indicated that a sports drink cause significant enamel demineralization effects on the bovine enamel surface among four beverages.
