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.

Ultrasound is able to have a multifaceted therapeutic effect in periodontitis. In therapeutic doses, it affects a variety of local tissue reactions, stimulates compensatory, restorative, protective and adaptive mechanisms.Ultrasound in dosages used in clinical practice does not have an independent, direct antibacterial effect. In this regard, in the treatment of periodontitis, where the microbial factor plays an important role, it is advisable to use antiseptic solutions as a contact medium for ultrasonic effects. The study of the comparative effectiveness of low-frequency and high-frequency ultrasonic effects in combination with the domestic antiseptic preparation miramistin, which, with high antibacterial effectiveness, is characterized by the absence of adverse side effects, in the treatment of periodontitis, is of significant scientific and practical importance.

Ultrasound refers to physical factors that can have a multi-sided therapeutic effect in periodontitis. In therapeutic doses, it affects a variety of local tissue reactions, stimulates compensatory, restorative, protective and adaptive mechanisms. For ultrasound therapy modern industry offers two types of devices that are able to generate ultrasonic vibrations in a wide frequency range: low frequency (2040 kHz) and high frequency (more than 800 kHz).The comparative study of the use of low-frequency and high-frequency ultrasound therapy in the complex of therapeutic measures for periodontitis is now of great scientific and practical interest.

BACKGROUND: The study of dental problems characteristic of geriatric patients is becoming increasingly relevant. As a person ages, the entire dental system undergoes physiological and functional changes. To eliminate the adverse effects of oral diseases, prolong the period of remission, preventive measures, constant monitoring of the level of hygiene, dispensary supervision of elderly and senile persons are necessary. AIM: This study aimed to determine the prevalence and intensity of dental diseases in the following older age groups: young elderly (6574 years old), old elderly (7584 years old), and very old elderly (85 years old and older). MATERIALS AND METHODS: A dental examination of 183 patients was carried out using a modified card for assessing the state of the dental status, according to guidelines of the World Health Organization. RESULTS: Analysis of dental morbidity in the older age group showed that the most common dental diseases in this group were extractions of lossened teeth caused by caries and periodontal diseases. Following a comprehensive dental examination of elderly patients and people with senility, the intensity of KPU and OHI-S was 19.760.52 and 2.710.12, respec-tively, and this indicates the poor hygienic state of the oral cavity of this population. CONCLUSION: Data support the untimeliness and inadequacy of dental care in elderly patients and people with senility. This necessitates the development of special treatment and prophylactic programs for this population, aimed at reducing dental morbidity.
