In vitro protection against dental erosion afforded by commercially available, calcium-fortified 100 percent juices.

Background: Calcium in acidic beverages can decrease a person's risk of experiencing dental erosion. The authors compared the pHs and titratable acidities of commercially available calcium-fortified and unfortified 100 percent juices, and enamel and root surface lesion depths after they were exposed to different juices.

Methods: The authors measured the pH and titratable acidity of calcium-fortified and unfortified 100 percent juices.
