    摘要: Oral compositions comprising a first and a second abrasive are provided. The first abrasive preferably has an Einlehner hardness of greater than about 5 mg loss per 100,000 revolutions, and the second abrasive preferably has an Einlehner hardness of less than about 5 mg loss per 100,000 revolutions. A ratio of the first abrasive to the second abrasive ranges from about 1:1.6 to about 1.6:1, and the first and second abrasives are preferably present in the oral composition at an amount of about 13% to about 21% by weight, respectively. The pellicle cleaning ratio of the oral composition is greater than 100 and the radioactive dentin abrasiveness is preferably less than 200, and in certain embodiments, preferably less than about 175. Methods of using the oral compositions are also provided.
