Abstract


AIM: To compare the erosive effect of different light and sugar free beverages in relation to their regular version, on dentin. MATERIALS AND METHODS: Bovine root dentin samples were randomized into 9 different types of drinks (each n=12): Coca-cola®, Light Coca-cola®, Coca-cola® Zero, Guaraná Antartica®, Guaraná Antartica® Zero, Sprite®, Sprite® Zero, Del Valle® Passion fruit juice and Del Valle® Light Passion fruit juice. During each one of the 10 experimental days, the samples were subjected to 3 erosive demineralization (by immersion of the sample in the studied drink) and remineralization (by immersion of the sample in artificial saliva) cycles. Profilometry was evaluated at the end of the 1st, 5th and 10th days. For each type of drink, the data were tested using 2 way ANOVA and Bonferroni test (p<0.05). RESULTS: Erosive cycling with regular cola resulted in a higher wear on the first day, on the 5th day the regular drink was similar to zero and greater than light version, on the 10th day there was no difference between the versions of cola drink. For the Sprite drink there was difference between the versions just in the 10th day, in which the higher wear was promoted by the zero version. For guaraná and juice beverages there was no differences between versions in relation to the resulted erosive wear. CONCLUSION: Erosive tooth wear promoted by light and sugar-free or regular versions of soft drinks and juices showed distinct behaviours over the cycling time.
