As a result of the study, it was found that the removal of dental plaque using low-frequency ultrasound and ozonized contact medium in chronic generalized catarrhal gingivitis of young people can significantly improve the state of microbiocenosis of the gingival sulcus. The preservation of the main resident species is noted, occasional transient species disappear and the frequency of isolation of aggressive representatives of beta-hemolytic streptococci and periodontopathogenic species decreases. When using ozonated water for the removal of dental deposits, the efficiency of eradication of the microbiota of the gingival sulcus, especially of representatives of aggressive species, is higher than when removing dental deposits without the use of ozonated water.

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.
