Abstract
Abstract: The problem of hypersensitivity of hard tissues of teeth remains relevant in modern dentistry to this day. Despite the fact that the market of dental products is saturated with ultramodern means to reduce the sensitivity of hard tissues of teeth, the issue associated with the relief of pain remains open. To develop a new approach to solving this problem, localized hypersensitivity of the 2nd degree of hard dental tissues was treated in 40 patients aged 20 to 45 years of both sexes. According to the concept of biomimetic/bioemulation, which became the scientific basis for the study, a toothpaste containing a mixture of bioactive microparticles of carbonate hydroxyapatite with zinc-substituted, similar to the structure of human teeth (biomimetic nanocrystals microRepair®) was used. There was a statistically significant prolonged decrease in the sensitivity of hard tooth tissues when using professional toothpaste with bioactive microparticles, provided its combined use in clinical conditions and at home, with daily use in the form of brushing teeth, compared with its single-component application at a specialist's appointment.
