The aim of this study was to determine the effectiveness of high calcium
milk and casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) on
enamel erosion caused by chlorinated water. Thirty-six bovine enamel samples
without wear or caries 3x4 mm in size were placed in acrylic blocks. All specimens
were randomly allocated into 3 groups (n=12/group): CPP-ACP in the form of
paste, Anlene ™ concentrated milk and a control (no treatment). All specimens
were soaked in chlorinated water (pH =5.0) at room temperature for 72 hours
following by soaking in artificial saliva for 30 minutes. Then, microhardness was
determined using a microhardness tester. Data were analyzed using a one-way
ANOVA and paired t-test. The microhardness value change in the control group
was significantly higher than the other groups. No significant differences were
seen between the 2 study groups. High calcium milk and CPP-ACP enhanced
remineralization of enamel erosion caused by chlorinated water.
