Clinical Results
Clinical study results demonstrate that DIFOTI images of teeth have higher diagnostic value than images obtained with conventional X-ray film*. The percentage of correctly diagnosed tooth caries (sensitivity) is higher with DIFOTI than with radiographic film. DIFOTI's performance is higher by factors of two, four and ten times for proximal, occlusal, or smooth surfaces, respectively. The percentage of correctly detected sound surfaces (specificity) is approximately the same.
The dentists involved in the study had only a few hours of training in reading DIFOTI images, as compared to professional lifetime training in reading radiographic images.
