As a general rule, the abrasivity of a dentifrice is unrelated to its physical form-- i.e., whether it is in powder or paste form. The factor that determines whether a particular dentifrice is more or less abrasive is the abrasive system used. Most such products use hydrated silica, but some also use dicalcium phosphate, calcium carbonate, sodium bicarbonate, or zirconium silicate. Those products using silica tend to have higher abrasivity scores, but these may vary according to polishing agent concentration and other ingredients. Hope this helps...
