PROGNOSTIC VALUE OF SOME CHEMICAL ELEMENTS IN THE ORAL FLUID OF PEOPLEWHO USE REMOVABLE DENTURES IN THE PROCESS OF STONE FORMATION

This work confirms a multifactorial effect on stone formation processes in the oral cavity of persons who use removable dentures, including an important role of macro- and micronutrients, namely, calcium, phosphorus, magnesium and zinc. The study of these elements was conducted in oral fluid and dental deposits and removable denture bases. Correlations between the level of oral hygiene and contents of chemical elements in oral fluid of people with removable dentures were found. With the increase in Ca / Mg, Ca / P, Ca / P / Mg ratios, the risk of stone formation was still observed in patients with “good” and “satisfactory” integral index of oral hygiene. The tendency to the formation of dental deposits is caused by the redistribution of calcium, phosphorus, magnesium and their correlations, as well as zinc ions content in the different environments of the oral cavity in people with removable dentures. On the basis of correlation connection between the concentration of magnesium and zinc ions in oral fluid in people who use removable dentures constructions, and values of integral index of oral hygiene (r = 0.53, r = 0.72), we can claim the existence of inhibition mechanisms in stone formation processes in the mouth. With the simultaneous correlation of Ca / Mg ?11, Ca / P ? 0.5 and Ca / P / Mg ? 11/19/1 in oral fluid in people who use removable dentures constructions, a high probability of deposits formation both on the teeth in the mouth and on the bases of removable dentures exists.
