Abstract:
The influence of addition of silicone oil to toothpastes was investigated in vitro using a laser reflexion technique and a profilometer. Acrylic plates were subjected to brushing in a brushing machine containing a toothpaste-water slurry. Four different toothpastes were used with and without the addition of 10% silicone oil. The results showed that the addition of silicone oil to a toothpaste decreased the abrasion rate and made the surface of the treated material smoother than after brushing with the original toothpaste.
