FIELD: medicine, stomatology.
SUBSTANCE: composition contains about 10 to 13 weight percent of water and abrasive low-structured precipitated silica dioxide, which has the refraction index about 1.439 to 1.450, index of lipid uptake about 90 to 120 mL/100g, optical transmission more than 60% and Brass Einlehner abrasion value less than 5 mg loss/100 000 rev. In addition, dental care agent has opacity index less than 50 and RDA about 50 to 200, refraction index about 1.439 to 1.450.
EFFECT: abrasive efficiency is increased.
