Radiotracers: The numbers that are assigned can vary from one study to the next, but usually the toothpaste, brush and liquid mimicking saliva is brushed onto a radioactive material which is then traced to see how much is removed. Several universities and research facilities have done it this way.

Good Question: Most toothpastes have quite low abrasiveness. I would need to know what you are looking for. Are you concerned a toothpaste would roughen fillings, or veneers or crowns? In most situations any mainstream toothpaste would be fine. If you are looking for a more scientific method of evaluation i would have to refer you to a research institute. Best to you.
