СПОСОБ ПОВЫШЕНИЯ МИКРОТВЕРДОСТИ И КАРИЕСРЕЗИСТЕНТНОСТИ ЭМАЛИ ЗУБОВ

摘要

FIELD: medicine. ^ SUBSTANCE: method involves covering gingival mucous membrane with screen substance like wax or photocurable Koferdamm before applying laser radiation treatment. Water or 30-35% aqueous hydrogen peroxide solution is sprayed over dental surface or bleaching gel diluted with hydrogen peroxide is applied. The dental surface is next exposed to continuous diode laser radiation with wavelength selected from bandwidth of 800-970 nm during 15-300 s. Laser radiation power density belongs to bandwidth of 10-100 W/cm2. Radiation energy dose is in the range of 40-3000 J with dose density being equal to 200-20000 J/cm2 diode laser power being equal to 2.8 W, light beam diameter being equal to 3.5-5 cm when being 1 to 2 mm far from the dental surface. When exposed to laser radiation, the dental surface is uniformly scanned with laser beam. ^ EFFECT: enhanced effectiveness and safety of the procedure. ^ 6 cl, 4 tbl
