In Vitro Assessment of the Abrasion Resistance of Two Types of Artificial Teeth Submitted to Brushing

Abstract

Purpose

To assess the effect of brushing with different solutions on the abrasion resistance of two types of acrylic resin teeth.

Materials and Methods

Maxillary premolars from two types of acrylic teeth (Biotone and Biotone IPN) were divided into six groups (n = 12), according to the solution used during brushing: distilled water (control), coconut soap, or dentifrice. A mechanical brushing machine was used to simulate approximately 1 year of brushing (11,000 strokes). The weight loss (WL) of teeth was obtained from the difference between the initial (IW) and final weight (FW) of each specimen, and the mean of percentage of weight loss (PWL) was calculated for each group. Data were analyzed using the Kruskal-Wallis test, followed by Bonferroni's post-test comparison (α = 0.05).

Results

A statistically significant difference was found for the factor solution (p < 0.001). Brushing using dentifrice caused the highest values of weight loss (–0.50%), in comparison with the groups brushed with coconut soap (0.00%) or distilled water (0.00%).

Conclusions

For both types of artificial teeth, brushing with dentifrice produced higher abrasion than brushing with coconut soap or water.
