Background: Osteoporosis is a metabolic bone disease commonly seen in elderly people and women. It is characterized by decreased bone mineral density leading to increased tendency to fracture. It has increased incidence in postmenopausal women. Dental radiographs can be used as a tool to identify the same. With the advancements in technology, cone beam computed tomography (CBCT) can be used for evaluation of alveolar bone changes and thus serve as a valuable predictor for osteoporosis.
Aim: To assess the alveolar bone changes in postmenopausal osteoporotic women using CBCT.
Objectives: • To assess pattern of bone loss as either horizontal or vertical in character.
• To assess mandibular cortex index (MCI), mandibular cortex thickness (MCT), mental index (MI) and bone loss.
• Thus to estimate the alveolar bone changes in postmenopausal osteoporotic women using CBCT.
Materials and methods: The present study was conducted in department of Oral Medicine and Radiology at Saveetha Dental College. Totally 91 women above 50 years of age were included in this study. Ethical committee clearance was obtained from the scientific committee of the university. Patients who were willing to replace their missing teeth by implant was evaluated by CBCT. Cone beam computed tomography used was ORTHOPHOS 3D, Sirona (Germany) at 90 Kvp, 14 mAS. MCI, MCT, MI and bone loss were assessed from the radiograph. The results obtained were subjected to statistical analysis using Statistical Package for Social Science (SPSS) software version 17.0 for Windows.
Results: In our present study, the mean age was 56 years. The endosteal margin was normal in 50%, mild in 19% and severe in 22% of the total subjects. There is no significant relationship in mental index between right and left side at the mental foramen region. The bone loss is angular in 46% of the RESEARCH ARTICLE 10.5005/jp-journals-10012-1138 subjects and horizontal in 45% of the subjects. There was a statistical significance between mental index and Mandibular cortical index which was done using one-way ANOVA (0.019). post hoc multiple comparison revealed statistical significance in MI’ of normal endosteal margin and MI’ of mild endosteal margin (0.021).
Conclusion: Thus to conclude, determining the rate of success in replacement of teeth especially using an implant, the density of bone is considered as an important factor. Further studies with larger samples will be helpful to establish a significant relationship between radiomorphometric indices and osteoporosis. Future studies comparing with gold standard dual energy X-ray absorptiometry (DEXA) can be done to standardise the correlation of radiomorphometric indices and osteoporosis.
