抄録

Abrasion of denture base resin by dentifrice manufactured for dentures was compared with that by ordinary tooth paste.<BR>Denture base samples were prepared using microwave-polymerized base resin. Using a brushing abrasion tester, the samples were brushed one hundred thousand times to determine the amount of abrasion and the surface roughness. SEM observation was also carried out. In addition, the X-ray diffraction and thermal weight of the dentifrice were measured.<BR>Brushing with the dentifrice for dentures resulted in a larger amount of abrasion compared to the ordinary tooth paste. Thus denture base resin was found to be liable to be abraded by brushing with the dentifrice manufactured for dentures. SEM observation and measurement of the surface roughness demonstrated that the surface of denture base resin underwent large changes by brushing with the dentifrice manufactured for dentures.<BR>The results of this study by SEM observation, X-ray diffraction measurement, and thermal weight measurement suggested that the difference in abrasiveness was due to the differences in the kind and grain size of the polishing material contained in dental paste.
