*2.1. Participants and Data Collection*

The questionnaire was created and distributed with the Google Forms application (Alphabet, Mountain View, CA, USA). The survey was distributed online to dentists registered in the College of Dentists of Oradea. The respondents were informed about the purpose of the research and the use of the collected data. The continuation of the questionnaire was assumed as an agreement to take part to the survey. No incentives were offered to the voluntary respondents. The inclusion criteria were dentists registered at that time by the Romanian College of Dentists, Oradea Department, working in public or private dental clinics or Dental Emergency Units. The exclusion criteria were retired or unemployed dentists, incomplete questionnaires (not fully filled in) and questionnaires returned after the deadline. The survey was sent to 125 dentists who previously agreed to receive news or questionnaires; 93 of them filled in the surveys (response rate was 74.4%). We excluded ten questionnaires because the respondents were retired dentists. Finally, 83 forms were included in our databases and considered for the research. In November 2020, 457 dentists were registered at the Oradea College of Dentists (metropolitan area and other cities in the department) so the sample is relevant for dentists working in the region.
