Abstract
Osteoporosis screening using dental X-Ray images has been growing an interesting research. Existing methods for osteoporosis screening have been performed using the dental periapical or panoramic in X-Ray images. There was limited research using both the periapical and panoramic due to the expensive cost of obtaining data. This paper presents a combination of the periapical and panoramic images for osteoporosis detection. The images processing was performed to obtain the shape-based features of the porous trabecular bone on both the dental radiograph images. The important features were selected from the extracted features. These selected features were chosen for osteoporosis detection using the decision tree. The quantitative evaluation used confusion matrix. It was found accuracy rate to be 73.33%, sensitivity rate to be 72.23, and specificity rate to be 72.23% for data testing.
Highlights
Dentists often use radiographs images to support their diagnosis [1][2][3]
Changes in trabecular and cortical mandible radiographically appearing on the images are the first sign of osteoporosis which can be found by dentists [4]
Several studies have been done related to the osteoporosis screening using the periapical radiograph images [10][11][12] as well as the panoramic radiograph images [7][13][14]
Summary
Dentists often use radiographs images to support their diagnosis [1][2][3]. The panoramic and the periapical radiograph is kind of extra oral and intraoral assessment which is very widely used by dentists because it is fast, easy to operate, and its cost is relatively inexpensive. Several studies have been done related to the osteoporosis screening using the periapical radiograph images [10][11][12] as well as the panoramic radiograph images [7][13][14]. Previous studies in [15] had performed porous features selection but they used only the periapical images for osteoporosis screening. This study proposes a model for detection of osteoporosis through the panoramic and periapical radiograph images using the selected shape-based porous trabecular bone features. These features were performed by [13][15].
