Abstract
Background: Recent investigations have shown that panoramic radiography might be a useful tool in the early diagnosis of osteoporosis. In addition, bone turnover biochemical markers might be valuable in predicting osteoporosis and fracture risks in the elderly, especially in post-menopausal women. Aim of study: To evaluate the relationship between the mandibular radiomorphometric indices using panoramic radiography in osteoporotic and non-osteoporotic females detected by biochemical markers of the bone turnover and spine BMD bone mineral density, and to obtain a possible means of early detection of osteoporosis by panoramic radiography. Subject and Method: Evaluation of mandibular cortical width (MCW), gonial angle index (G0) and panoramic index (PI) was carried out on panoramic radiographs of 60 Kurdish females who were divided equally into three groups: control (20-30 years), non-osteoporotic postmenopausal aged 50 years and above, and osteoporotic postmenopausal aged 50 years and above. Lumbar vertebrae BMD was measured by DXA scan and divided into three groups according to WHO criteria as follows: normal (T score>-1.0), osteopenic (T score, -2.5 to -1.0) and osteoporotic (T score<-2.5). Serum alkaline phosphatase (ALP), serum calcium (S.Ca) and vitamin (VD) were measured by biochemical test. After collecting the data, they were analyzed using SPSS version 21. Results: Significant positive correlation (r) was observed between bone mineral densities BMD of lumbar vertebrae and MCW(r=0.633) and PI(r=0.477) of mandibular indices, and negative correlation was observed between G0(r= -0.298) and BMD of lumbar vertebrae. There was significant (P<0.05) association between the MCW, PI and ALP in the three groups. But there was no significant association (p>0.01) between GO and MCW, PI. The results did not demonstrate a statistically significant relationship between VD and BMD. Conclusion: Dental panoramic radiographs can be used in clinical practice to assist identifying individuals with low bone mass, which is valuable in the prevention of osteoporotic fractures in elderly women. Post menopausal women in the age range 50 and above with thin MCW will be at increased risk of low bone mineral density and osteoporosis. VD and Go were undependable in detecting osteoporosis.
