Dental caries remains the most common disease of the oral cavity. The analysis of literary sources proves that the incidence of dental caries in children burdened with somatic pathology is significantly higher than in healthy children. Domestic studies of recent years testify to the growth of pathology of the musculoskeletal system and connective tissue in children. Therefore, the goal of our study was to develop a treatment-prophylactic complex and clinical evaluation of its effectiveness in this pathology. For this purpose, 60 children aged 5-6 years were under observation,
comprised of two main and two control groups. The preventive complex included 3 stages: hygienic education and
upbringing of children and their parents, which was carried out in preschools at "Dental Health Lessons"; professional oral hygiene (performed 2 times a year, and in children with unsatisfactory oral hygiene 2-3 times a year); a differentiated approach to the selection of exogenous caries prevention means (deep fluoridation of all teeth was carried out twice a year, "Tooth Mouth" was used at home in courses of 10 days; children with unsatisfactory oral hygiene and with UCTD were carried out 3-4 times a year). In cooperation with a pediatrician, the children's nutrition
was corrected. The children of the control groups were given preventive measures and sanitation of the oral cavity
following local protocols for the provision of medical care. Indicators of caries intensity, increase in intensity, reduction of increase in caries intensity evaluated the effectiveness of preventive measures. Therefore, after two years of using the preventive complex, the indicators of the reduction of the increase in caries intensity increased, which indicates the effectiveness of the use of this complex in children with MSS pathology and MSS pathology against the background of UCTD, regarding the course of the carious process by creating favorable conditions for enamel maturation.
