Results of the study of the mineralizing capacity and hydrogen indicator of the oral fluid in children taking into account the dental status and age

Abstract

Caries is one of the most common dental diseases in children, which is characterized by enamel demineralization. The condition of the hard tissues of temporary and permanent teeth is influenced by a significant number of factors, including the oral fluid that is in direct contact with the teeth. The mineralizing ability of the oral fluid affects the state of the hard tissues of the teeth, that is, the acid resistance of the enamel, the decrease of which leads to demineralization with further progression of the carious process. The aim of the study was to study the indicators of the mineralizing potential and the pH of the oral fluid in children aged 7–12 years with caries of temporary and permanent teeth and to compare them with the indicators of children with intact teeth. The dental status of 223 children aged 7–12 years was studied (in each child, the condition of the hard tissues of the teeth was determined and the DMFT (Decayed, Missing and Filled Teeth) in the temporary bite, DMFT/dmft (Decayed, Missing and Filled Teeth) in the variable bite, dft (decayed and filled teeth) in the permanent bite index was calculated), mineralizing potential and pH of the oral fluid were calculated. Indicators were compared in children with and without caries. The course of caries of both temporary and permanent teeth in children occurs against the background of a decrease in pH and microcrystallization of oral fluid. This is especially noticeable in children who have affected permanent teeth. The caries rate of temporary and permanent teeth has inverse correlations with the pH and microcrystallization index of the oral fluid. The obtained data suggest the need for primary and secondary prevention, aimed at improving oral homeostasis indicators, planned remediation, which will make it possible to reduce the prevalence and intensity of caries in children, which will be the subject of our further research. Keywords: caries, intact teeth, pH of oral fluid, microcrystallization of oral fluid.
