CBCT ASSESSMENT OF MANDIBULAR BONE QUALITY AND QUANTITY IN PATIENTS WITH OSTEOPOROSIS
Osteoporosis is characterized by weakened bones that put people at higher risk of fracture, especially in patients who have an advanced degree of damage and who follow or not treatment for osteoporosis. The aim of the study was to compare mandibular indices and mandibular bone density with the skeletal status investigated by osteodensitometry in patients with osteoporosis, with or without treatment. Material and methods: 40 patients with osteoporosis, divided into two equal groups, were evaluated by CBCT for the assessment of some mandibular indices that indicate the bone density at the cortical and cancellous bone level. The statistical analysis was performed with SPSS20.0, p=0.05. Results: For most of the evaluated parameters, higher values were recorded in the group of participants with osteoporosis but without treatment compared to the group of participants with osteoporosis, with treatment. The results showed a significant association between the mandibular cortical index and the type of treatment, with G1 patients presenting in a proportion of 25% the mandibular cortical index type 2, while G2 patients presented the mandibular cortical index type 2 in 58.33% of cases. In the case of G2 patients the cortical bone density values are significantly higher compared to the values corresponding to G1 patients. There are no significant differences in regard to cancellous bone density values between groups. Conclusions: The density of the mandibular bone is closely correlated with changes in the density and implicitly of the state of the skeleton of patients with osteoporosis, usually evaluated by bone osteodensitometry. The CBCT technique provides sufficient radiographic information that helps dentists and oral and maxillofacial surgeons to play an important role in the early diagnosis of mandibular osteoporosis.
