Abstract

Abstract: Purpose: To study general dental practitioners (GDPs) ability to detect calcified carotid artery atheromas (CCAAs) in panoramic radiographs (PRs) and if their diagnostic accuracy in long term is improved after a short training programme. Methods: Fourteen GDPs had their diagnostic accuracy regarding CCAA in PR assessed at baseline, 2 weeks and 1 year after training. Comparison was made with a reference standard based on consensus results from two experienced oral and maxillofacial radiologists. At each session, 100 radiographs were assessed individually by the GDPs. After the baseline assessment, the GDPs participated in a 2‐hour training programme comprising a lecture and diagnostic training by calibration. The GDPs results before and after training were compared, as well as between follow‐up sessions. Results: A significant improvement in diagnostic accuracy was observed with increased sensitivity (from 41.8% to 55.7%, P = 0.02) without a significant decrease in specificity (from 87.2% to 86.7%, P = 0.87). The Kappa values also increased (from 0.66 to 0.71, P = 0.04). At 1‐year follow‐up, the improvement compared to baseline remained significant. There were no significant changes between the 2‐week and 1‐year follow‐up assessment. Conclusion: A short training programme can significantly and sustainable improve GDPs diagnostic accuracy regarding CCAA.
