| Abstract |
|
The purpose of study was to assess the influence of acidic drinks on the erosion of tooth enamel and the effect of fluoridated saliva on the remineralization. Twenty five drinks were sampled. The erosive potential and remineralizing effect were measured by the tooth surface microhardness test. The pH of most drinks were below pH 5.5. Reduction rates of enamel surface hardness by the flavored carbonated drink were 16.90%, 25.11%, 35.10%, and 41.62% after 5, 10, 30, and 60 minutes of demineralization, and recovery rates by remineralizaing solution were 61.52%, 67.96%, 72.13% and 75.93% after 1, 24, 48, and 72 hours of remineralization, respectively. The results suggest that the most drinks in the markets have the potential to erode the teeth and that erosion occurs fast but remineralization proceeds slowly. |
