Relevance. In adolescence, focal demineralization after orthodontic treatment is highly prevalent. This, in turn, leads to symptomatic hypersensitivity in the absence of other predisposing factors (recessions, exposure of cervical dentin, increased abrasion, etc.). Reviewed the mechanism for reducing hypersensitivity and remineralizing of calcium-sodium phosphosilicate, also the effectiveness of using a prophylactic toothpaste with this component in adolescents.Materials and methods. A single-center, non-comparative open study was conducted to evaluate the effectiveness of the Sensodyne Restoration and Protection toothpaste at the Department of Pediatric Dentistry and Orthodontics, USMU for 4 weeks. 22 adolescents aged 14-16 years with focal demineralization of enamel in the stain stage after completion of orthodontic treatment participated in the study.Results. The use of toothpaste with calcium-sodium phosphosilicate after a month of use leads to a decrease in the hygiene index by 23.38%, a decrease in hypersensitivity according to the results of the Schiff air index by 56.94% (p ≤ 0.05), and a tendency to an increase in the level of mineralization and a decrease in areas of white spot lesions.Conclusions. Toothpaste with calcium-sodium phosphosilicate has a cleansing effect and reduces sensitivity and can be recommended for adolescents with focal demineralization against the background of orthodontic treatment.
