The study protocol: COVID-19 awareness and perception among dentists in the Russian Federation.

OBJECTIVE

Coronavirus disease 2019 (COVID-19) has spread rapidly worldwide since it has been first identified in November 2018. It is transmissible via air droplets from infected individuals. Close contact between dentists and patients has aggravated the pandemic situation in Russia. It is necessary to reduce the risk of spreading COVID-19 during dental appointments by adhering to the Centers for Disease Control and Prevention (CDC) and the World Health Organization (WHO) recommendations.

SUBJECTS AND METHODS

Questionnaires were developed to assess levels of COVID-19 infection and preventive measures in private and state-funded dental practices in Moscow and other cities in Russia. Two questionnaires were developed to assess the COVID-19 situation among dental professionals and their patients. The first, for dentists, included four domains: demographic data, signs, and symptoms of COVID-19 experienced by dentists, personal protective measures taken by dentists, and presence or absence of dental practice during the pandemic. For dentists' patients, the second included domains regarding their health status after their dental appointment. 1,500 questionnaires were sent to different cities and regions of Russia; 1,011 questionnaires (67.4%) were returned. We used statistical observation (monitoring) and clustering to analyze the data. The x2 was used to check the significance level.

RESULTS

We found a direct relationship between those patients who contracted COVID-19 after dental treatment by those dentists who did not follow recommended measures in the dental clinic. However, patients were less likely to become infected after dental treatment by those dentists who followed the measures, such as the disinfection of surfaces and dental equipment several times a day, the wearing of medical masks by all patients, and the airing of the dental office after each patient for 10 minutes.

CONCLUSIONS

Dentists wearing an FFP2 or FFP3 respirator, as well as a sterile disposable microfiber medical gown, prevented their patients from becoming infected with COVID-19 at dental appointments and, as a result, the spread of the virus. A key aspect of this study is its knowledge regarding preventive measures against COVID-19. The findings of this study can potentially help in formulating strategies to reduce the prevalence of COVID-19.
