BARBOSA, Carolina Silveira et al. Calcium glycerophosphate supplemented to soft drinks reduces bovine enamel erosion. J. Appl. Oral Sci. [online]. 2012, vol.20, n.4, pp. 410-413. ISSN 1678-7757. http://dx.doi.org/10.1590/S1678-77572012000400004.
OBJECTIVE: This in vitro study evaluated the effect of calcium glycerophosphate (CaGP) supplemented to soft drinks on bovine enamel erosion. MATERIAL AND METHODS: Four pH-cycles were performed, alternating demineralization by the beverage and remineralization in artificial saliva. RESULTS: Mean wear (±SD, µm) was 7.91±1.13, 7.39±1.01, 7.50±0.91 and 5.21±1.08 for Coca-Cola® without CaGP or containing CaGP at 0.1, 1.0 or 2.0 mM, respectively, while no wear was detected for CaGP at 5.0 and 10.0 mM. Corresponding figures for Sprite Zero® without CaGP or containing CaGP at 0.1, 1.0, 2.0, 5.0 or 10.0 mM were 8.04±1.30, 7.84±0.71, 7.47±0.80, 4.96±0.81, 3.99±0.10 and 1.87±0.12, respectively. CONCLUSION: Supplementation of both beverages with CaGP seems to be an alternative to reduce their erosive potential.
