The effectiveness of non-drug correction of chronic periodontitis in patients who have undergone a new coronavirus infection on the severity of oxidative stress

Purpose of the study. To evaluate the effect of the use of non-drug correction of chronic periodontitis in patients who have undergone a new coronavirus infection on the severity of oxidative stress. Material and methods. A total of 156 patients with CP aged 26 to 63 years participated in the study (the average age was 44.7±6.15 years). When dividing patients by gender, the majority were men — 86 patients (55.1 %). 126 patients out of 156 examined had a history of COVID-19 with a prescription of 1 to 6 months. At the first stage, by stratified randomization, all patients (156 patients), depending on the presence of a history of NCI, were divided into two unequal groups: 126 patients with CP who underwent COVID-19, and 30 patients with CP who did not have NCI. At the second stage, 126 patients with CP who underwent COVID-19 were divided into 4 groups using simple fixed randomization: a control group, two comparison groups and a main one. The control group received standard periodontal therapy (SPT), regulated by clinical guidelines. In comparison groups 1 and 2, SPT was supplemented, respectively, with applications of liposomal gel with DHA and NILI. In the main group, a complex of liposomal gel and NILI was used as an adjunct to SPT. Results. The SPT included professional oral hygiene with ultrasonic scalers and curettes of the Piezon Master 700 device (EMS, Switzerland). The removal of dental deposits was carried out using air-abrasive technology Aig-Flow (EMS, Switzerland). Individual oral hygiene was trained and monitored. Conclusion. The factors contributing to the development of inflammatory periodontal diseases, namely carious cavities, wedge-shaped defects, overhanging edges of fillings, were also eliminated.
