MICROBIOLOGICAL STUDY OF ENDODONT ARISING AGAINST THE BACKGROUND OF PREVIOUS COVID-19

Abstract

Justification. In our previous study, bacterioscopy was used to analyze the contents of the root canals of teeth in patients who had been ill with COVID-19. The presence of coccal flora was revealed in all cases (100%) and in 89 cases (76.1%) elements of yeast-like Candida fungi were recorded. Based on the data obtained, the expediency of conducting a microbiological examination of the endodonts in this group of patients in order to further study their physico-chemical properties and correct the treatment regimen for gangrenous chronic pulpitis and aggravated forms of periodontitis was determined, which determined the relevance of this study.The aim of the study was to identify the features of the mycotic flora of the endodonts in patients who had previously undergone COVID–19.Materials and methods. A bacteriological study of the contents of the root canals was conducted in patients who had previously been ill with a new coronavirus infection at different times, with a diagnosis of "exacerbation of chronic periodontitis", "chronic gangrenous pulpitis", "acute purulent periodontitis" in order to identify fungi of the genus Candida in the root canal system of the tooth, which was taken during mechanical treatment with a sterile endodontic instrument (n=49).Results. This bacteriological examination of the contents of the patients' endodonts not only confirmed the bacterioscopy data, but also concretized the previously obtained results. In the final study, black Candida Albicans colonies were observed in 95.92% of cases. No growth of Candida Albicans colonies was observed in 2 cases (4.08%).Conclusion. The study showed that in the treatment of similar patients, it is advisable to take into account the high risk of infection of the tissues of the periodontal complex with fungi of the genus Candida. It is advisable to supplement the standard protocols of endodontic treatment with physical exposure, for example, laser radiation, or additional drug exposure with antifungal drugs.
