Objectives. The purpose of this study was to measure the relative tooth abrasivity of the domestic dentifrices marketed in Korea.
Methods. The authors measured the relative tooth abrasivity of thirty-two types of dentifrices. Assessment of tooth dentin abrasivity produced by different dentifrices was carried out on extracted bovine teeth in the laboratory and was tested by the surface profile measurement method. Calcium pyrophosphate was used as a reference abrasive and was assigned a score of 1.000 for the profilometry method.
Results. The degree of the relative tooth abrasivity of the dentifrices varied from 0.048 to 1.095. The dentifrices were divided into 4 groups according to the Euclidean distance data mining.
Conclusions. The abrasivity of all the tested dentifrices was at an acceptable level for consumers.
