Surface Roughness of Restorative Materials after Tooth Whitening
ثبت نشده
چکیده
Thisin vitro study was conducted to evaluate the effect of tooth whitening on the surface roughness of dental restorative materials using AFM. Two hybrid resin composites and nano-ionomer were fabricated in samples with 2 mm thickness and 6 mm diameter. No changes in roughness was observed for all three materials tested after 14 days of bleaching with 20% carbamide peroxide (CP), compared to the control group. It can be concluded that 20% CP home bleaching did not cause changes in surface roughness of the tested materials.

Commentary. Effect of whitening dentifrices on the surface roughness of commercial composites.
PURPOSE Our study aimed to test the null hypothesis that whitening and non-whitening dentifrices affect similarly the surface roughness of commercial microhybrid composites, independent of the brushing time. MATERIALS AND METHODS One hundred and ninety-two disc-shaped specimens of Filtek Z250 (3 M/ESPE, St. Paul, MN, USA) and Rok (SDI, Australia) were built up and randomly assigned to 24 grou...

PURPOSE The aim of the present in vitro study was to assess the effect of bleaching agents on eroded and sound enamel specimens. MATERIALS AND METHODS Enamel specimens prepared from human permanent anterior teeth were incubated with different bleaching agents containing active ingredients as 7.5 or 13.5% hydrogen peroxide or 35% carbamide peroxide, ranging in pH from 4.9 to 10.8. The effect o...

متن کاملComparative Evaluation of Surface Roughness of Three Different Composite Resins Following Polishing with a Two-Step Technique
Background and Aim: Nowadays, demand for same–color restorative materials, especially resin composites, is increasing. Access to the smooth surface with minimum level of surface roughness significantly results in more beauty, and the reduction of the accumulation of the plaque, gingival inflammation, and tooth discoloration. the aim of this study was surface roughness of three different composi...
