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.
