Abstract
Currently, no standard abrasive scale exists for dental prophylaxis pastes. Manufacturers determine their definition of abrasive grit levels. The purpose of this study was to measure resulting surface roughness on bovine enamel of a representative sample of prophylaxis pastes. The study consisted of a survey of prophylaxis paste manufacturers, a pilot study and an analysis of bovine tooth specimens. Prophylaxis pastes, pumice and toothpaste comprised the sample. Equipment was constructed for applying abrasives to specimens at 2500 rpm for five seconds under a load of 145-grams. Pre and post-test surface roughness readings were recorded. Repeated measures ANOVA determined that the change in roughness was significantly different among all pastes (p< .0001). A surface roughness scale of current products was developed and results showed that few pastes actually “polished” and created a smoother surface. Clinicians must evaluate individual patient’s needs, consider selective polishing, and make evidence-based decisions when choosing a product.
