Subject. Changes in mineralization and the presence of microbial plaque on the surface of hard dental tissues depending on the duration of oral hygiene. Objectives. To study the raman-fluorescent characteristics of the surface of dental hard tissues depending on the duration of oral hygiene in patients undergoing radiation therapy. Methodology. The study was conducted on the basis of the Department of Orthopedic Dentistry and Orthodontics at BSMU. In accordance with the purpose of the work, a study was conducted in which 80 people participated. The study included the study of the mineralization of the surface of the hard tissues of the teeth, the level of microbial plaque on the surface of the teeth. The data were recorded on the 1st day after the start of radiation therapy. During the study, the agroindustrial complex “Inspector M” was used. Results. Mineralization of hard tissues and fluorescence significantly decreases over time during dental hygiene. There were no significant differences between the main group and the comparison group. Conclusion 1. During the hygienic treatment of the oral cavity, according to Raman-fluorescence spectroscopy, the mineralization of the surface of the hard tissues of the teeth decreases (in the area of the tooth neck from 270.8 ± 6.7 to 173.6 ± 7.2; equator from 411.9 ± 9.1 to 350.2 ± 6.4; cutting edge from 411.9 ± 9.1 to 311.7 ± 4.6). 2. During the hygienic treatment of the oral cavity, according to Raman fluorescence spectroscopy, the fluorescence of the surface of the hard tissues of the teeth decreases (in the area of the tooth neck from 5361.6 ± 12.2 to 4613.1 ± 16.1; equator from 4873.6 ± 14.8 to 4123.0 ± 12.1; cutting edge from 4672.3 ± 14.7 to 3925.4 ± 12.5) 3. The lowest degree of mineralization of the hard tissues of the teeth is in the area of the tooth gang (270.8 ± 6.7), the largest in the area of the equator of the tooth. 4. According to the fluorescence data, the largest amount of plaque is present in the area of the tooth gang (5361.9 ± 14.6), the smallest in the area of the cutting edge (4672.4 ± 13.1).
