COVID-19-Related Health and Practices Among Dental Hygienists

Completed

• Conditions: Occupational Problems; Coronavirus Infection; Anxiety; Depression; Severe Acute Respiratory Syndrome; SARS-CoV Infection
• Interventions: Other: No intervention

• Registration Number: NCT04542915
• Lead Sponsor: American Dental Association

Brief Summary

As dental practices reopen their practices during a global pandemic, the risk of 2019 novel coronavirus (COVID-19) infection that dental hygienists face in providing dental care remains unknown. Estimating the occupational risk of COVID-19, and producing evidence on the types of infection control practices and dental practices that may affect COVID-19 risk, is therefore imperative. These findings could be used to describe the prevalence and incidence of COVID-19 among dental hygienists, determine what infection control steps dental hygienists take over time, describe dental hygienists' employment during the COVID-19 pandemic, and estimate whether infection control adherence in dental practice is related to COVID-19 incidence.
