Abstract
Dentifrice preparations exhibiting optimum cleaning ability and reduced abrasion may be obtained by employing therein low levels of a dental abrasive material (e.g., about 10-20% calcium pyrophosphate) in combination with an inert filler and one or more detergent agents. Additionally, increased therapeutic effectiveness may be achieved where anticariogenic adjuvants such as sodium fluoride, NaF, and stannous fluoride, SnF.sub.2, are incorporated in such dentifrice preparations.
