Descrição: Aim To compare the diagnostic accuracy of digital enhancement filters in the diagnosis of vertical root fractures. Methodology The sample consisted of 40 single‐rooted teeth randomly divided into two groups: experimental and control. Vertical root fractures were induced in the experimental group using a universal testing machine. All teeth were individually radiographed with three different horizontal angles using the Digora Optime® digital system. Three observers separately examined the original and filtered images (3D Emboss, Negative, Sharpen and Shadow). The area under Receiver Operating Characteristic curve values (Az) for each protocol were compared by one‐way anova with post hoc Bonferroni test. The significance level was set at 5%. Results The highest Az value was obtained using the Sharpen filter, with significant differences from the original and other filtered images (P < 0.05). The 3D Emboss filter had the lowest Az value, which was significantly different from the other filtered images (P < 0.05). Conclusion When using the Digora Optime® system, the ‘Sharpen’ filter is recommended to improve the radiographic detection of vertical root fractures.
