Liljeborg A, Tellefsen G, Johannsen G. The use of a profilometer for both quantitative and qualitative measurements of toothpaste abrasivity. Abstract: Aim: To evaluate the abrasivity of different toothpastes both quantitatively and qualitatively with a profilometer technique and to correlate these findings to the radioactive dentin abrasivity (RDA) value. Materials and methods: Acrylic plates were exposed to brushing in a brushing machine with 11 different toothpastes. The results were evaluated using a profilometer. A surface roughness value (Ra‐value), that is, a qualitative measurement, and also a volume value, that is, a quantitative measurement, were calculated from the profilometer results. These values were then correlated to each other and to the RDA‐value. A comparison between RDA, Ra and volume measurements was performed using linear fitting procedure. Results: The results showed that the correlation between RDA and Ra measurements was low ( R 2 = 0.04) and also that the correlation between RDA and volume measurements was low ( R 2 = 0.00002). Correlation between Ra and abraded volume was high ( R 2 = 0.87). Conclusions: It is important to consider not only the RDA‐value when evaluating toothpaste abrasivity. From the profilometer results both a quantitative (volume) and qualitative (roughness) measurement of the abrasivity of a toothpaste can be obtained.
