Panoramic X-Ray Analysis Using Edge Detection Method on Mandibular Cortex

Abstract

Panoramic X-Ray is one type of image that can be used in the health world to identify various diseases and damage that occur in the jaw and teeth. This study aims to identify the inferior mandibular cortex and detecting mandibular resorption as an indication of osteoporosis. Several stages are conducted in the proposed method. The first step in the pre-processing stage to be done is cropping, to obtain the Region of Interest (ROI). The next step in the pre-processing stage is image improvement to get image with favorable quality. The extraction stage is conducted in two steps. In the first step the image is processed using the edge detection method. In the second step of the extraction stage we use quantum edge detection to produce the upper edge of inferior mandibular cortex. Then, the lower border of inferior mandibular cortex is projected to obtain a difference between the upper and the lower border of the inferior mandibular cortex. As the result of study, we can identify bone resorption in the inferior mandibular cortex. Resorption of the mandibular cortex is an indication of osteoporosis. It is concluded that damage to the jaw bone can be seen from the result of panoramic X-Ray images after performing image processing.
