Background: As SARS-CoV-2 is detected in the infected patients' saliva, dental employees performing aerosol-generating procedures are at high risk of being infected/spreading the infection.

Aims: This study aimed to assess the impact of restarting the high-risk procedures for COVID-19 infection in dental practice during the pandemic on the anxiety levels of dental employees.

Methods: All dental employees (dentists, nurses, data entry/cleaning staff) working in a university dental clinic were invited to the study and eighty-one employees (response rate: 97.5%) participated in the study. The volunteers' anxiety was measured consecutively twice with the State-Trait Anxiety Scale: First, on the day prior to restarting the high-risk procedures and the second, on the day these procedures began. Data were analyzed using t tests and the repeated measures ANOVA.

Results: The state anxiety level of the dental employees increased significantly on the day that the high risk procedures were restarted (mean 42.6 vs. 49.0, d = 0.6, P < 0.001). Concerning the subgroups, the increase in state anxiety levels was significant for females (t = 3,7; d = 0,8; P < 0.001), dentists working in departments of endodontics and restorative dental care (t = 3,5; d = 0,9; P < 0.001) and nurses (t = 2,8; d = 0,9; P < 0.001). The analysis showed no significant difference in trait anxiety levels between the assessment days (mean 44.0 vs. 44.2, P = 0.9).

Conclusions: Restarting the high-risk procedures for COVID-19 infection in dental practice during the pandemic seems to be an extra stressor for dental employees' who already have high anxiety levels during the pandemic.
