Impact of Milk on Erosion/Abrasion of Enamel and Dentin - an in Situ Study

This in situ study aims to investigate * the protective potential of milk and fluoridated milk on erosive wear of enamel * the protective potential of milk and fluoridated milk on erosive wear of dentin * to compare to protective potential of milk and fluoridated milk with products containing casein phosphopeptide-amorphous calcium phosphate * to compare the protective potential of milk and fluoridated milk with a fluoridated toothpaste or stannous-chloride containing fluoride solution (SnCl2/AmF/NaF)
