ABSTRACT
Currently, there is no comprehensive data in the literature on the clinical and laboratory assessment of periodontal status in patients who have had COVID-19 infection.
The aim of the study. To determine the condition of periodontal tissues in patients who have suffered COVID-19 infection.
Objects and methods. 101 patients took part in the study. The patients were divided into 3 groups: control (patients with intact periodontium), first (patients with periodontal disease without a history of COVID-19 infection) and second (patients with periodontal disease and previous coronavirus infection). Patients were examined according to modern clinical protocols.
Results and discussion. The n average value of the OHI-S index in the first and second groups was 0.57 ± 0.03 and 0.59 ± 0.04, respectively. The average value of the gingival GI index was 1.8 ± 0.3 and 0.8 ± 0.07 in the second and first groups, respectively. The average value of the PMA index in the second group was 49.5 ± 3.1 %, while in patients of the first group it was 8.9 ± 0.8 %. The average value of the periodontal index PI in the second and first groups was 3.4 ± 0.4 and 1.5 ± 0.2, respectively. According to the results of PCR diagnostics the presence of bacteria T. denticola, P. gingivalis and B. forsythus in the contents of periodontal pockets was detected in patients of the second group.
Conclusion. According to the results of clinical and laboratory assessment of the condition of periodontal tissues, in patients with a history of coronavirus infection, a change in the indicators of objective tests of the condition of periodontal tissues was observed towards deterioration, which may indicate an adverse effect of COVID-19 infection on the condition of periodontal tissues.
