摘要: doi: 10.1111/j.1741-2358.2010.00422.x Weight loss and changes in surface roughness of denture base reline materials after simulated toothbrushing vitro Objective: To evaluate the weight acrylic resins brushing tests. Material methods: Ten specimens each material (Tokuyama Rebase II-TR, New Truliner-NT, Ufi Gel Hard-UH Lucitone 550-L) were made. The wear (mg) by (Ra μm) specimen was determined before brushing. placed on machine a total 20 000 cycles performed. results values submitted to anova followed Tukey’s test (p = 0.05). Results: mean L statistically higher (p 0.05). Only for L, increased roughness. After toothbrushing, there no significant difference between NT. highest during tests observed L. Before tests, NT exhibited roughness. Conclusion: Brushing resulted increase only resin
