A method has been developed for testing dentifrice abrasiveness which is based on a commercial toothbrush motor that operates a brush with only one or two tufts and on the application of dentifrice to a disk of neutron-irradiated dentin. Greater precision was found when only one tuft was used. The wear by two commercial dentifrices depended on the force on the brush and on the concentration during testing.
