Sports drinks are beverages that contain carbohydrates and supplements to add fluid and nutrients in the body so many people consume these beverages. Every sports drinks contain citric acid with different concentrations which is one of the factors causing erosion. The concentration of a drink and the duration of time in consuming these drinks can also affect erosion. Purpose of this study was to determined the influence of concentration and exposure duration citric acid solution on the surface hardness of tooth enamel. This study is experimental laboratory tested using Vickers Microhardness were analyzed by descriptive qualitative. Specimens in this study of 13 premolars were divided into 1 for control, 6 for the concentration of 31.99 mg/L (K.1) and 6 for the concentration of 63.98 mg/L (K.2) with a time of 5, 20, 90 minutes. The result demonstrate the value of hardness on the control is 350.33 VHN, the K.1 is 369-320 VHN and the K.2 is 331-264 VHN. Based on immersion time of the K.1, within 5 minutes is obtained of the average value is 323 VHN, in 20 minutes at 356 VHN and in 90 minutes is 329 VHN. The K.2 with 5 minutes is obtained of average value is 321 VHN, in 20 minutes at 321 VHN and in 90 minutes obtained 274 VHN. The results can be concluded that citric acid solution with concentration and exposure duration different to lower the hardness of tooth enamel. The longer the teeth are exposed to a solution of citric acid will decrease the surface hardness of tooth enamel, the higher the concentration of citric acid solution will decrease the surface hardness of tooth enamel while demineralization process has not occurred. Keywords : Citric acid, enamel, Vickers, surface hardness of tooth enamel
