| Outline of Final Research Achievements |
We developed computer programs that scans dental panoramic radiographs and dental cone-beam CT images to screen possible osteoporosis and to detect the type of tooth.
These programs were evaluated using clinical images in a certified dental image library that established for this project.
The diagnostic sensitivity to detect possible osteoporosis was 94.5%, and the specificity was 94.9%. An algorism using deep convolutional neural network enabled to classified the type tooth correctly in more than 90% of cases.
