Abstract
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.
