024 – Diagnostic performance of digital 2D periapical radiography and 3D cone beam computed tomography
- Chief Investigator A: Dr Ernest Ekpo
- Chief Investigator B: Prof Patrick Brennan
- Associate Investigator: Dr Kehn Yapp
Introduction
There is limited information available about the diagnostic performance of commonly used imaging modalities in dentistry.
Aims
- 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.
Rationale
There is a lack of meaningful data on the diagnostic performance of common digital 2D and 3D dental imaging modalities and how clinicians interpret dental radiographs. Image interpreter-related factors that drive diagnostic performance in dental imaging are rarely explored.
Methodology
A free response, factorial study will be undertaken. Two modalities will be included: PA radiography and CBCT imaging, a range of diseased and non-diseased case types, and a range of reader types: graduate dentist, moderately experienced dentist, highly experienced dentist, dental specialist and medical radiologist. Data of these readers will be examined to establish their characteristics that drive performance.
What are the expected outcomes?
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. Such data will help dentists to make informed choices of the best imaging investigation to improve diagnostic efficacy.
