Q2. What is the impact of the dentin slurry on dentin wear?
toothbrushes with smaller filament stiffness caused higher dentin wear in all toothpaste slurry groups (RDA 20, 50 and 100) except for the paste-free control group (RDA 10).
Q3. What is the effect of toothpaste slurry on dentin wear?
Conclusion: Abrasion of eroded dentin increased along with the RDA-value of the toothpaste slurry and with decreasing filament diameter of the toothbrush.
