FIELD: medicine, pharmaceutics. ^ SUBSTANCE: group of inventions refers to oral care compositions for dental erosion and/or abrasion control (i.e. prevention, inhibition and/or treatment). The offered tooth brushing composition for dental erosion control contains alkali fluoride as a fluoride ion source, an amphoteric surface-active material representing cocamidopropyl betaine, and a silicon dioxide dental abrasive as an abrasive. The tooth brushing agent have relative dentineabrasion (RDA) 20 to 60 and pH within 6.5 to 7.5 and does not contain a phosphate buffer, a water-soluble salt C10-18 alkylsulphate and calcium salt. A method of dental erosion and/or abrasion control involves application of an effective amount of said composition in a requiring individual. ^ EFFECT: use of said ingredients of the composition combined with RDA and pH control provides intensification of fluoride absorption by enamel, ability to protect against acid erosion stimuli, and to harden repeatedly enamel after an effect of such erosion stimuli. ^ 13 cl, 8 tbl, 7 ex, 4 dwg |
