FIELD: medicine.
SUBSTANCE: dental bracket is fixed onto an extracted tooth. A centre surrounding the dental bracket on a vestibular surface is limited by a wax layer. The tooth is immersed into a separated container with a demineralising gel consisting of (wt %): calcium dihydrophosphate - 0.04-0.08, lactic acid - 0.8-1.0, praestol 2510 - 3.0-4.5, sodium hydroxide - 0.4, distilled water - the rest. Then, the container with the teeth is placed in a thermostat at pH=4.5 for 96 hours.
EFFECT: more sharp demineralisation centre.
