JUSTIFICATION THE APPOINTMENT OF FLUORIDES TO THE PERSONS, WHO CONSUME DRINKING WATER WITH DIFFERENT VOLUMES OF FLUORINE

Abstract

Prevention of tooth decay is still an urgent dental problem worldwide that is determined by the high rate of its prevalence and intensity. Caries-preventing effectiveness of fluorine is nearly commonly accepted, but fluorines are also known to produce unwanted effects. That's why a differentiated individual approach to the appointment of fluorides is one of the most important tasks of a dentist. Research aim. Justify the appointment of fluorides to the persons, who consume drinking water with different volumes of fluorine. Materials and research methods. The research involved 30 patients aged 20-25, who consumed drinking water with different volumes of fluorine. In order to provoke changes in the permeability of the etched enamel for methylene blue, it was applied sodium fluoride solution followed by comparing the color intensity of enamel before and after load of fluorine and analysis of the results. Results of research and their discussion. Reducing of the color intensity on research areas of enamel to blue color, compared with the control area, indicates the ability to absorb fluoride by the tooth enamel. This is a direct indication of necessity of fluorine-preventive appointment to the patient. Increase of the color intensity on research areas of enamel to blue color, compared with control area, indicating the presence of an excess of fluorine ions in tooth enamel. This is an indication of inexpediency of fluorine-preventive appointment to the patient. Conclusions. The present method of determination of fluoride in the enamel of permanent teeth makes it possible in a clinical setting, quickly, in one session, without tooth extraction without using precious equipment to determine the content of fluoride in tooth enamel. And provide reasonable individual recommendations for each patient, on the application of fluoride for the prevention of dental caries.
