ENAMEL RESISTANCE OF TEMPORARY TEETH IN CHILDREN 3-6 YEARS OLD AND INFLUENCE OF ORAL FLUIDS ON IT

Abstract

Caries is the most common dental disease among children. Its development is associated with demineralization of enamel, which is the result of the action of acids on the surface of the tooth, which are produced by plaque microorganisms. It is the combination of local, general factors and low enamel resistance that leads to the development of the carious process. The acid resistance of tooth enamel in children plays an important role, which is connected with the processes of de- and remineralization that occur throughout life. The resistance of enamel to caries is determined by the properties of the oral fluid. Microcrystallization of oral fluid has an individual character and changes with age, which is due, on the one hand, to changes in its composition and functional capacity in different age periods, and on the other hand, to different levels of caries intensity. The mineralizing properties of oral fluid are due to the acid-alkaline balance. The hard tissues of the teeth of children aged 3-6 years without caries are in a more favorable environment for maintaining their caries resistance, which is due to better indicators of oral fluid, such as mineralizing properties and pH index, compared to children with caries-affected teeth. The results of the examination showed that the resistance of enamel decreases in children who have a significant number of teeth affected by caries, which is due to the deterioration of the mineralizing properties of oral fluid, a decrease in its pH. The studied indicators always had the worst values in children with a decompensated degree of caries activity, regardless of age, which determines the presence of a cariogenic situation in the oral cavity of these children, which contributes to a further decrease in enamel resistance and the possibility of caries. Considering the multifactorial nature of the etiology of caries, it is necessary to continue the study of the relationship between the occurrence of caries in children, the influence of oral fluid and the morphological features of the chewing surface.
