The results of the study are of primary importance for the maintenance of oral cavity health in musicians-instrumentalists which is indispensable for the maintenance of their successful professional activity.

Physiotherapy makes it possible to effectively influence all the links in the pathogenesis of periodontitis. The use of ultrasound plays a special role in the treatment of periodontal diseases. With the help of ultrasonic vibrations, drugs (ultraphonophoresis) can be introduced into the tissue. For its implementation, water and oil solutions of medicinal substances are used. In periodontal practice, ultrasound is most often used to remove dental plaque. It is of scientific interest to use low-frequency ultrasound in combination or in combination with physical factors that have a pronounced antibacterial effect, such as ozone . High oxidizing properties of ozone provide its therapeutic effect, manifested in disinfecting, metabolic, immunomodulating and deodorizing effects. When conducting local ozone therapy in the oral cavity, it is necessary to accurately dose the concentration of ozone, therefore, in our opinion, the use of ozonized solutions and oils in dentists is safer and more promising. The combined and combined effects in the treatment of periodontitis of low-frequency ultrasound and ozone therapy, in the production of ozone using short ultraviolet radiation, will provide a comprehensive therapeutic effect, which consists in suppressing the vital activity of pathogenic microorganisms and stimulating metabolic processes in the tissues of the macroorganism.

The dental status of 148 patients aged 18 to 22 years. All students who were diagnosed with generalized catarrhal gingivitis (46) were carried out removal of dental plaque with ozonation of the environment. The results of clinical studies indicate the high efficiency of the use of the removal of dental plaque using low-frequency ultrasound using an ozonized contact medium in the treatment of chronic generalized catarrhal gingivitis. The treatment carried out using this method contributed to the elimination of inflammation, the normalization of blood circulation in the gums. 3 months after the treatment, the achieved effect was preserved, which was confirmed by the data of clinical and functional research methods. Despite a slight increase in inflammation in the gums and a deterioration in microcirculation indicators, even a year after treatment, the indicators characterizing the degree of inflammatory and microcirculatory disorders in the gums retained significant differences compared to the values obtained before the treatment.

BACKGROUND: Inflammatory periodontal diseases in the world affect from 80 to 100% of the adult population, therefore, the issues of timely prevention of the development of destructive changes in periodontal tissues and the treatment of gingivitis in young people are of great practical importance. Currently, extensive research is being conducted in the field of periodontics, new methods of treatment are being proposed, but a wide arsenal of applied means is not always effective, its use often leads only to short-term improvement, therefore, the problem of treatment remains relevant and necessitates the development and improvement of means and methods that contribute to the relief of the inflammatory process and increase the remission period. AIM: To investigate the effectiveness of removing dental plaque using low-frequency ultrasound and an ozonized contact medium in the treatment of catarrhal gingivitis of young people. MATERIAL AND METHODS: 54 patients (age, aged 1822 years) of RUDN University were examined and treated for chronic generalized catarrhal gingivitis. All patients were divided into two groups of 27 people each. In the first group (control group), dental plaque was removed without ozonation of the contact medium. In the second group, dental deposits were removed with ozonation of the contact medium. Hygiene level was assessed using the Simplified Oral Hygiene Index. The intensity of inflammation was assessed using the papillarymarginalalveolar index. RESULTS: The papilla bleeding index was used to assess bleeding gums. The resistance of capillaries to vacuum was determined according to the method of Kulazhenko using the auditory-verbal learning test-DESNA device. Rheoparodontograms were assessed qualitatively and quantitatively. CONCLUSION: Removal of dental plaque using ozonized water as a contact medium helped reduce inflammation, normalize local blood circulation in the periodontium, lengthen the remission period, and stabilize the process.
