Sumario:AIM: This experimental study was designed to focus on the effects of bleaching on toothbrush abrasion in three types of composites with different filler size. MATERIALS AND METHODS: Forty eight disks were prepared from three types of composite and divided into 6 groups. In the first three groups the abrasion test was done. The remaining groups were bleached and the abrasion test was performed. The weight of the samples before and after abrasion was measured. Statistical analysis was done with one-way ANOVA and Duncan test. RESULTS: There was a significant difference in abrasion of composites with different filler size (P < 0.05). The most amount of abrasion was observed in Z100 after being bleached. An increase in abrasion was noticed in all three types of tested composite after bleaching. CONCLUSION: According to the findings, it is suggested to use a nano filled resin composite for restoration if the bleaching treatment is required.
