About Orion-C19

Orion. A hunter of shadows, himself a shade.

Homer, Odyssey, II. 572.

The COVID-19 pandemic is continuing to spread around the world, with more than 127 million confirmed cases and 2.7 million deaths across nearly 200 countries. Due to the aggressive and fast-growing nature of this pandemic, evidence to describe multiple manifestations of the disease albeit limited is continuously evolving.

The ORION C-19 research project stems from the need to understand the effects that COVID-19 have on peoples' oral health and the effects of that oral health have on the course of the disease.

Multiple manifestations of acute and post-acute COVID-19 have been described, including cough, fever, headache, fatigue, attention disorders and hair loss. Importantly, oral manifestations among COVID-19 patients have been also reported. These may include loss of taste, mouth sores, ulcer, erosion, vesicle, fissured or depapillated tongue, among others.

However, little evidence about the extent and prevalence of oral health conditions in people with COVID-19 in acute and chronic stages is available. Importantly, no studies are examining the impacts that oral health conditions have on these peoples’ general health and quality of life.

Therefore, this study explores oral health conditions of COVID-19 in adults at different stages of the disease.

Purpose of the study

This study investigates the oral manifestations of COVID-19 in adults. Data collected from this study will help us to understand:

  • the characteristics and frequency of oral health conditions in COVID-19 adults at different stages of the disease
  • how the oral manifestations of COVID-19 change over time
  • what is the effect of oral health conditions on COVID-19 severity
  • what impacts COVID-19 have on peoples’ quality of life

Study information

We are recruiting adults participants (18+ years) who have had COVID-19 with or without symptoms.

People taking part in the study will be asked to respond an electronic questionnaire to collect information on COVID-19 symptoms, oral health conditions and quality of life, and takes about 10 minutes to complete.

Participants do not need to provide any personal details such as name, date of birth or contact details.

If you need more information, please do not hesitate to contact us.
