It is a well-known fact that osteoporosis affects the people with old age and remains unnoticeable until the patient presents with fracture. Various studies in the literature reveal that panoramic radiographs may prove to be beneficial in the detection of Osteoporosis in patients. Henceforth this present study was aimed to validate the use of Klemetti Index (KI) on panoramic radiographs so as to detect osteoporosis in the patients at an early stage.


60 postmenopausal women were selected. A panoramic radiograph was taken to grade their mandibular cortex on the basis of Klemetti Index. All the panoramic radiographs were evaluated by 5 different Oral Medicine and Radiology specialists. Later all the patients were subjected to dual energy X-ray absorptimetry (DEXA) scan for bone mineral density evaluation. The results were evaluated statistically.


The average accuracy of the five observers to demonstrate normal bone, osteopenia and osteoporosis when compared to DEXA scan was 58.08%, 63.3% and 64.74% respectively. The observations of the 5 observers on the basis of KI were not statistically different from the BMD evaluation done with the help of DEXA Scan.


Panoramic radiographs can be used as a screening tool for the evaluation as well as early detection of osteoporosis with the usage of Klemetti Index.
