Abstract

Background : Panoramic radiography plays a very important role which provides suggestive signs of possible systemic disease. For example, decrease in the mandibular cortical thickness on panoramic radiography is a sign of osteoporosis. Population at risk of osteoporosis is in postmenopausal women. Nowadays, DXA remains the gold standard in detection of osteoporosis due to the highly effectiveness of DXA. Mandibular Cortical Index (MCI) has been developed to evaluate osteoporosis in the cortical area of the mandible using panoramic radiographs. Purpose : Measure the sensitivity, specificity, and accuracy of MCI on panoramic radiographs postmenopausal women with osteoporosis and without osteoporosis. Methods : In this study, panoramic radiographs of 18 postmenopausal women with osteoporosis and 18 postmenopausal women without osteoporosis were evaluated for MCI. Subjects are selected by criteria such as women aged over 50 years old, had been diagnosed by a doctor using the DXA, and have a good oral hygiene. Results : The study showed that the category C2 (mildly to moderately eroded cortex) was more found than the category C1 (normal cortex) and C3 (severely eroded cortex) in postmenopausal women with osteoporosis. Category C1 (normal cortex) was more found in postmenopausal women without osteoporosis. Measurements MCI yield sensitivity 11.11%, specificity 72.22%, and accuracy 41.67%. There is no significant differences between observers in evaluating the sensitivity, specificity and accuracy of MCI. Conclusion : MCI is not effective as a screening tool in detecting osteoporosis.
