Artigo IPEN-doc 06855 Evaluation of the precision in the dentifrice abrasivity measurements obtained by a radiotracer method2000 - CAMARGO, I.M.C.; ZOPPE, C.C.C.; SAIKI, M.; VASCONCELLOS, M.B.A.The radiotracer method was applied to evaluate the precision of the measurements of abrasivity data obtained for dentifrice samples and for abrasive agents (silica and calcium carbonate). This method consists of measuring 32P transferred to a dentifrice or abrasive slurry when an irradiated dentin is submitted to a brushing simulation. Results obtained for abrasivity indices had good precision with relative standard deviations lower than 11.8%. Comparisons made between our abrasivity index data with those obtained at the Oral Health Research Institute of Indiana University also showed a good agreement.Artigo IPEN-doc 02823 Application of radiometric method to the evaluation of dentifrice abrasivity1996 - SAIKI, M.; CAMARGO, I.M.C.; VASCONCELLOS, M.B.A.; PANZERI, H.; LARA, E.H.G.Artigo IPEN-doc 07146 Abrasiveness evaluation of silica and calcium carbonate used in the production of dentifrices2001 - CAMARGO, I.M.C.; SAIKI, M.; VASCONCELLOS, M.B.A.; AVILA, D.M.Artigo IPEN-doc 07141 Evaluation of the precision in the dentifrice abrasivity measurements obtained by a radiotracer method2001 - CAMARGO, I.M.C.; ZOPPE, C.C.C.; SAIKI, M.; VASCONCELLOS, M.B.A.
