In the middle-third of the root canals, IRR lesions were simulated using Da Silveira protocol. Later, the specimens were X-rayed to create the test group (TG). All images acquired were exported with seven enhancement filters plus the original image. Three examiners used a five-point Likert scale to evaluate the images regarding the presence\/absence of IRR. Diagnostic efficacy was assessed from sensitivity and specificity results. Comparison among filters was performed by using receiver operating characteristic (ROC) curve analysis. <\/jats:p><\/jats:sec><jats:sec><jats:title>Results: :<\/jats:title><jats:p> Moderate values of Kappa interexaminer (0.403\u20130.620) and high values of Kappa intraexaminer (0.757\u20130.915) were observed. The best performance occurred in the CG (p &lt; 0.05). Original images presented the greatest sensitivity and area under the ROC curve (0.595\u20130.750), while the Endo filter presented the greatest specificity (0.952). Inversion and Pseudo-3D images produced the greatest doubt in the diagnosis, significant for CG with the Pseudo-3D filter (p &lt; 0.05). <\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions: :<\/jats:title><jats:p> The Original and \u2018Endo\u2019 filters should be chosen as it offers greater diagnostic ability and allows more confidence during the evaluation.
