Project 026 – Knowledge, attitude, practices and confidence of dentists performing dental treatment around the world during COVID-19 outbreak


COVID-19 continues to disrupt lives around the world. Different guidelines about the severity of the outbreak in various countries have been implemented, but uncertainties remain about the safety and efficacy of these new measures. There is a lack of a standardised approach to continue dental procedures in this challenging environment; but appropriate infection control is key.


To identify the gaps in dentists’ knowledge and attitudes towards infection control in a post-pandemic world.

Who can participate?

Dentists (general dentists and specialists) who:

  • Are practising in Australia; and
  • Have access to the internet.

What will you be asked to do?

Complete an online questionnaire that should take approximately 10 minutes of your time.

Why should you be asked to do?

  • Your practice may benefit from the outcomes of this study, leading to increased professional satisfaction by being able to provide improved care for you patients;
  • Be part of an eviDent project that will ultimately contribute to the practice of dentistry in Australia.

Project 024 – Diagnostic performance of digital 2D periapical radiography and 3D cone beam computed tomography 


There is limited information available about the diagnostic performance of commonly used imaging modalities in dentistry.


  • To assess the diagnostic performance of digital 2D periapical radiography compared to 3D cone beam computed tomography in the detection of dental abnormalities using a free response paradigm.
  • To identify factors affecting performance of both imaging modalities.

Who can participate?

Practising general dentists in Victoria.

What will you be asked to do?

You will be asked to interpret 60 periapical and 120 cone beam computed tomography images, spread over two reading sessions. This will be done in person on a provided computer workstation, at a location convenient for you.

You will perform a total of 180 image interpretations for this study. We anticipate it will take approximately four hours to complete the two reading sessions (two hours each session).

At the beginning of the study, we will ask you some demographic questions relating to your experience as a radiologist or dentist. You will have the opportunity to review your reports and receive feedback on your diagnostic performance.

Why should you participate?

  • This project is in collaboration with the Medical Imaging Optimisation and Perception Group at The University of Sydney, whose research publications in medical image perception are amongst the world’s best;
  • This is a world first study in dentistry using sophisticated measurement techniques and diagnostic performance assessment;
  • The results of this study will provide data never collected before; clinicians will be able to know how well diagnostic dental imaging performs and how diagnostic imaging is interpreted; and
  • This will help clinicians understand the factors that drive performance, which can be used to tailor strategies to improve diagnostic accuracy in dentistry.
