Panoramic radiograph analysis of trabeculae, cortical, and radius of condyle head in post menopausal women

The case of osteoporosis in Indonesia increases from time to time. One of three post menopausal women stricken with osteoporosis. Osteoporosis decreases bone density causing bone fracture. Method: Research subjects meeting inclusion criteria sign ethically-approved informed consent. Scanning by using Dual Energy X-Ray absorpsimetri (DEXA) and panoramic radiograph are conducted in Rumah Sakit Gigi dan Mulut (RSGM) Universitas Padjadjaran. Preprocessing using background-offset compensation is conducted to improve image quality with average value of the lowest variant. Feature extraction is conducted in micro structure of the trabeculae by using 3 methods (GLCM, histogram, and fraction analysis). Macro analysis is conducted by using 2 methods which are cortical width and resorption of head condyle analysis. Relationship of T-score = -7,046 + 10,227, mean fraction + 0,235 right cortical (Tka3) +0,027 right radius (R3). This model provides determination coefficient value of 32.1%. Panoramic radiograph could be used in order to determine bone quality based on micro and macro analysis of the condyle structures.
