Magnesium in the body and its role in the formation of dental morbidity SHEE "Uzhhorod National University", Uzhhorod, Ukraine Дана робота є фрагментом НДР кафедри стоматології дитячого віку ДВНЗ «Ужгородський національний університет» «Комплексне обгрунтування надання стоматологічної допомоги дітям, які проживають в умовах біогеохімічного дефіциту фтору та йоду» (№ державної реєстрації 0119U101329).Purpose. Analyze the literature on the role of magnesium in the formation of children's health, in particular dental status. Materials and methods. The research materials were scientific developments of domestic and foreign researchers. In the course of the research the bibliosemantic method and structural-logical analysis were used. The methodological basis of the study was a systematic approach.Results. The incidence of caries in children is growing, despite the great attention of researchers to this problem. The role of essential elements in shaping children's health is crucial. Magnesium, as a necessary macronutrient, plays an important role in the formation of the full structure of tooth enamel, but its role has not been sufficiently studied.Conclusions. Magnesium deficiency in the population is from 16 to 42%. Magnesium is a calcium antagonist, is actively involved in maintaining the stability of the crystal lattice of tooth enamel and, accordingly, its deficiency adversely affects the condition of the hard tissues of the teeth, especially in children.
