RATIONALE FOR THE USR OF FLUORESCENCE-BASED MONITORING OF ORAL HYGIENE STATUS DURING PATIENT DENTAL CHECK-UPS IN A DENTAL CLINIC SETTING

The article presents the rationale for using fluorescence diagnostics to objectively assess the hygienic condition of patients' oral cavities in a dental clinic. The relationship between various methods of its assessment is shown: classical subjective, as measured by the OHI-S, and digital fluorescence. Subject. The subject of this study is fluorescence diagnostics of the hygienic condition of the oral cavity of patients, carried out in a dental clinic. Objectives. To determine the efficiency of fluorescence diagnostics based on the bio-response of dental hard tissues and oral fluid samples to optimize personal oral hygiene methods. Methodology. The quantitative assessment of dental plaque was evaluated by calculating the OHI-S index. Fluorescence diagnostics were performed by the hardware and software complex (HSC) "InSpectrM" using a contact-stable measurement method, using a light guide with an individual attachment of the HSC "InSpectrM" with a laser radiation wavelength of 405 nm at a radiation power of 15 mW at the end of the light guide (with a signal recording time of 10-20 seconds). The results were evaluated using the automated HSC program by determining the integral value of fluorescence intensity, which is the area under the fluorescence curve in relative units (rel. units). Results. As a result of quantitative determination of the degree of plaque coverage of the tooth surface experienced a decrease in fluorescence intensity by 23% (p < 0.05), and in patients with a satisfactory hygiene indicator (group 2) - by 39% (p < 0.05) compared to the initial indicators (Figs. 1 and 2).
