The content of microand macroelements in the oral fluid at different intensity of dental caries

Introduction. Due to the high prevalence of caries, the monitoring of enamel and dentin state remains an actual problem in dentistry and contributes to the development of new methods for diagnosing and predicting a cariogenic situation in the oral cavity. One of these methods is the study of the remineralization and demineralization processes in the oral cavity and of the microelements′ and macroelements′ level in the oral fluid.

The aim of the study is to research the level of macroand microelements in the oral fluid in patients with different intensity of dental caries.

Materials and methods. 13 people aged 21 to 35 were examined, including 10 women and 3 men. Based on the results of the dental examination, 2 groups of subjects were formed: 1st (n=4) healthy individuals and patients with a compensated form of caries; 2st (n=9) patients with decompensated form of caries. The subjects collected oral fluid by spitting into a test tube on an empty stomach, after brushing their teeth and rinsing their mouth three times with distilled water. Three samples were taken from each subject on different days, a total of 39 samples. The content of elements (Na, K, Ca, Mg, Fe, P, Mn) was determined by inductively coupled plasma atomic emission spectrometry.

Results. An increase in the content of most microand macroelements (Na, K, Ca, Mg and P) in the oral fluid was found in patients with decompensated caries compared with the compensated form and healthy people (p<0,05). Perhaps, in the absence of a carious process or compensated caries, the mineral components are concentrated in hard tissues and the remineralization-restoration processes of the tooth mineral structures prevail.

Conclusion. The study of the content of Na, K, Ca, Mg and P in the oral fluid can be used to diagnose and predict the course of the carious process.
