    摘要: Dentifrice possessing superior cleaning and polishing characteristics comprising a silicious and calcined alumina abrasive system in an amount to provide an enamel abrasion to the dentifrice of above about 450, (as measured by the radioactive method) and about 0.005-1.0% and preferably about 0.1-1.0% by weight of a water soluble fluoride salt, such as sodium fluoride, sodium monofluorophosphate, stannous fluoride and the like, with or without raising the pH of said composition to preferably above about 7 so as to reduce said enamel abrasion thereof.
