Calcium glycerophosphate supplemented to soft drinks reduces bovine enamel erosion

Objective

This in vitro study evaluated the effect of calciumglycerophosphate (CaGP) supplemented to soft drinks on bovine enamel erosion.

Material and methods

Four pH-cycles were performed, alternating demineralization by the beverage andremineralization 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 forCoca-Cola^TM 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^TM without CaGP or containing CaGPat 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 reducetheir erosive potential.
