Radiographic evaluation of mandibular bone remodeling by mandibular cortical Index (MCI) in a Senegalese population

Background: People living with HIV may have several pathologic conditions in its body and bone is one of the organs affected by HIV infection. HIV-infected patients have been associated frequently with osteoporosis and lower bone mineral density (BMD) which may lead to the increasing risk of bone fracture. This situation may become more complicated in children and young age as it will affect the long-term bone quality and development later in life until the peak BMD is reached. Objectives: The aim of this study was to measure the mandibular bone quality using the mandibular cortical index (MCI) and panoramic mandibular index (PMI) in panoramic radiographs of HIV-infected children. Method: This study used descriptive cross sectional research design which analyzed panoramic radiographs of HIV-infected children and measured its mandibular bone quality. Total 43 panoramic radiographs of HIV-infected children were observed and analyzed qualitatively using mandibular cortical index (MCI) and panoramic mandibular index (PMI) were used for the quantitave measurement, as it have been widely used for assesing mandibular bone quality in previous studies. Mandibular cortical index (MCI) has 3 categories of cortical bone quality: C1 (normal cortex), C2 (mildly to moderately eroded cortex), and C3 (severely eroded cortex), while the normal ratio of mental foramen-inferior border of mandible to mandibular cortical length in panoramic mandibuIar index is about 0.3. Result: Mandibular cortical index (MCI) of 43 HIV-infected children consist of 4 samples in C1, 38 in C2, 1 in C3, while the panoramic mandibular index (PMI) of 43 HIV-infected children consist of 23 less than normal, 5 normal, 15 more than normal. Conclusions: The most number of mandibular cortical index (MCI) was C2 (mildly to moderately eroded cortex) and the most number of panoramic mandibular index (PMI) was less than normal of HIV-infected children.

Osteoporosis characterized by low bone mass/osteopenia can be identified using radiomorphometric indices in routine panoramic radiographs. This study estimates the prevalence of osteopenia in 50-80 years age group, using panoramic mandibular index (PMI), mental index (MI) and mandibular cortical index (MCI). PMI, MI and MCI were applied on 36 panoramic radiographs; MI and MCI were compared with PMI. The prevalence of osteopenia was 11.1% with PMI and 44.4% with MCI. Using MI, the prevalence was 2.8% and 33.3% with 3mm and 4.77mm threshold respectively. The prevalence of osteopenia detected was highest using MCI (44.4%). Considering PMI as gold standard, MI with 4.77 mm threshold showed better agreement with PMI.

Objective:Systemic lupus erythematosus is an autoimmune disease that affects multiple organs. It is well known that lupus patients have higher risk of osteoporosis, but if the disease affects mandibular cortical bone and alveolar bone is not fully established. The objective of this study was to evaluate periodontal disease defects and mandibular osteoporotic alterations in patients with lupus as compared to healthy patients using panoramic radiographs.Material and Methods:The panoramic radiographs of 72 patients with lupus and 360 healthy patients were evaluated for the presence of bone loss secondary to periodontal disease, classified as horizontal and vertical bone loss. We also assessed mandibular osteoporotic alterations by using the mandibular cortical index. Logistic regression analysis was applied to estimate the risk of mandibular osteoporotic alterations as well as horizontal and vertical bone loss in patients with lupus as compared to healthy patients.Results:There were no statistically significant differences between groups in the presence of horizontal bone defects and mandibular cortical indexes. However, patients with lupus demonstrated that patients with lupus were 2.17 more likely to present vertical bone loss than healthy patients.Conclusions:Patients with lupus might have higher risk of vertical bone loss than healthy patients due to pathophysiology of their disease. Further larger prospective studies should be performed to confirm our findings.
