| Abstract | ||||
| Tooth brushing of the esthetic restorative materials may results in their wear and subsequently negatively affecting their biological, esthetic and mechanical properties. The aim of the study was to compare the effect of oscillating-rotating (OS) and the sonic (V) power-driven toothbrushes on the wear of three different restorative materials. Materials and methods: three restorative materials were used; nano-hybrid composite Filtek™ Z250 XT, bulk fill resin composite Tetric N- Ceram Bulk Fill and highly viscous glass ionomer restoration Ketac™ Universal Aplicap™. With a total of 42 samples (10x2 mm), 14disc shaped samples were prepared from each material and randomly divided into two groups then subjected to wear with the two electric toothbrushes (n=7) for 60 minutes under toothpaste slurry. Change in surface roughness (Ra) and weight loss before and after wear testing was recorded and subjected to one-way ANOVA followed by Tukey post-hoc tests (with significance level P ≤ 0.05) to reveal the significant difference. Results: the highest Ra and weight loss values were recorded in samples subjected to wear by V toothbrush in three tested materials. However, there was no statistically significant difference between the tested materials with OS toothbrush. Conclusion: OS and V electric toothbrushes have the same effect on the surface topography of the tested restorative materials. | ||||
