About this study
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.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
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.

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
COVID-19 probable or confirmed case (time frame: 18 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04542915, which also lists 2 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
