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

Do you want to make informed choices of the best imaging investigation to improve diagnostic efficacy?

Get on board now!

There is a lack of data on diagnostic performance of digital 2D and 3D dental imaging modalities and how clinicians interpret dental radiographs. No evidence exists on the factors associated with improved diagnostic performance in this domain. This project will provide data on the diagnostic performance of digital periapical radiography relative to cone-beam computed tomography in endodontic disease detection and the factors that drive performance.

If you are a practising dentist in Victoria, we invite you 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; and
  • Identify factors affecting performance of both imaging modalities.

Participants will 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 dentist. You will have the opportunity to review your reports and receive feedback on your diagnostic performance.
