THE INFLUENCE OF SILICONE OIL IN TOOTHPASTES ON ABRASION IN-VITRO

The influence of addition of silicone oil to toothpastes was investiga ted in vitro using a laser reflexion technique and a profilometer. Acr ylic plates were subjected to brushing in a brushing machine containin g 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 r ate and made the surface of the treated material smoother than after b rushing with the original toothpaste.
