Objectives: The objectives of this study were to verify the level of ethical consciousness and decision-making of dental hygiene students in pandemic as coronavirus disease 2019 (COVID-19).
Methods: This study included 249 college students who were interested in new infectious diseases.
They completed a questionnaire on a 5-point scale, and data were analyzed by independent t-test, ANOVA, and correlation. Results: The perception of COVID-19 was moderate at 3.42 points. This was higher among males, first graders, emergency management students, those who received education and experienced self-quarantine. The level of ethical consciousness was moderate (3.89 points), which was higher in sophomores, emergency management students. Ethical decision�making was moderate, with a score of 3.44, and was higher in those with first grade, field practice training, and self-quarantine experience. The level of perception positively correlated with ethical consciousness (α=0.310, p<0.01). In addition, as the degree of ethical consciousness increased, the degree of decision-making also increased (α=0.539, p<0.01). Conclusions: In a crisis, involving the spread of COVID-19, providing prospective dental hygienists accurate information and an experience similar to that faced by patient is necessary for raising the level of ethical consciousness and decision-making.
