Relationship between the morphologic features of alveolar trabecular bone and systemic osteoporosis / 대한구강악안면방사선학회지

ABSTRACT

PURPOSE: The purpose of this study was to investigate the preliminary use of morphologic operation (MO) in analyzing trabecular pattern of alveolar bone for the predicting systemic osteoporosis. MATERIALS AND METHODS: Study subjects consisted of 35 females (average age 48.5 years) and 25 males (average age 25.8 years). Bone mineral density BMD (grams/cm2) of lumbar spine and proximal femur of these subjects were measured by a dual energy X-ray absorptiometry (DEXA). Regions of interest (ROIs) were selected from the digitized periapical radiographs of subjects' posterior jaw. A custom computer program processed morphology operations of ROIs. We compared mean values of 11 MO variables according to the osteoporotic group divided by the T-scores of DEXA. We also studied correlation between radiographic density and these MO variables. RESULTS: The mean radiographic densities insignificantly correlated with MO variables. There were statistically significant differences among the values of 9 MO variables according to the osteoporotic group. CONCLUSION: Morphologic operation can be effective in analyzing trabecular pattern of alveolar bone for the predicting osteoporosis.
