Abrasive Properties of Three DifferentToothpastes

Abstract

Objective: The main purpose of this study was to develop a simple reproducible system to compare abrasive effects of three different toothpastes. Materials and Methods: A specific mold was used to fabricate 37 samples made of po-lymethylmethacrylate. The samples were stroke by toothbrushes connected to a V8 Cross Brushing Machine in a solution of fluoridated toothpastes and distilled water. The samples were evaluated initially and also after 48 hours. The data were analyzed by one-way ANOVA test. Results: No significant differences was found among the three types of toothpastes after 25000 strokes (P=0.427). Conclusion: All the three toothpastes presented same abrasive properties.
