Perceived vulnerability to Coronavirus infection: impact on dental practice.

SARS-CoV-2 is a new virus responsible for the outbreak of the respiratory disease COVID-19, which has spread to several countries around the world, causing considerable consternation and a fear of contagions in global healthcare settings. The objective of this study is to identify, among Madrid's adult population, the impact of COVID-19 on self-perceived vulnerability, infectiousness, aversion to germs, and other behaviors in the current situation regarding dental practice. This cross-sectional observational study involves 1,008 persons randomly surveyed on the streets of Madrid, Spain between March 1 and March 8, 2020. Their perceived vulnerability to disease was measured using the perceived vulnerability to disease scale. An additional questionnaire evaluated basic sociodemographic aspects, medical history, personal hygiene behavior, willingness to go to certain places and the perception of the risk of contagion when going to a dental practice. There are significant differences by sex on the germ aversion subscale (p < 0.05) and in the risk of waiting in the waiting room (p < 0.01), tooth extraction ((p < 0.05), endodontics (p < 0.05) and fillings ((p < 0.05). Women consider the risk to be higher than men do. The risk group (over 60 and with systemic disease) has significant differences on the subscales of infectivity (p < 0.01) and germ aversion (p < 0.01). Our study shows high levels of vulnerability regarding contracting COVID-19 and avoiding dental care as perceived by the population over 60 years old and with a systemic disease.
