Abstract

Purpose: To determine whether toothpaste diluent type and dilution rate influence abrasion of dentin. Methods: Slabs of human root dentin (4 × 3 × 2 mm) were embedded in epoxy resin, ground and polished. Adhesive tape was placed on the specimen's surface leaving an exposed central area of 1 × 4 mm. Specimens (n = 15) were then brushed for 1,000 strokes in a reciprocal action brushing simulator using toothpaste that had been diluted in a carboxymethylcellulose-based artificial saliva (CMC) or deionized water (DW) from 1:1 to 1:4 (toothpaste:diluents, in weight). Control groups were brushed with undiluted toothpaste, CMC-based saliva or DW only. Brushing simulation was run at 300 g load at 37°C. After brushing, adhesive tape was removed and wear analyzed by optical profilometry. Results: One-way ANOVA (P< 0.0001) and Tukey's test revealed that, in general, wear depth (urn) declined with increasing dilution, regardless of the diluent. Brushing with CMC- or DW-only caused the least abrasion.
