Bone Mineral Density and Radiographic Mandibular Body Height
Estera Balcikonyte, Irena Balciuniene, Vidmantas Alekna
The panoramic based measurements (the total height of the mandibular body and the height from the lower border of mandible to the lower border of the mental foramen) and Mandibular Ratio index were compared to bone mineral density of the lumbar area L2-L4 by dual-energy x-ray absorptiometry (DXA) measurements in 130 women. Correlations of Mandibular Ratio indexes with parameters reflecting skeletal status measured by DXA were not statistically significant. Significant correlations between Mandibular Ratio indexes and the total height of the mandibular body (r = 0.409, p<0.001 (right side); r =0.403, p<0.001 (left side)), and with the height from the lower border of mandible to the lower border of the mental foramen (r = -0.671, p<0.001 (right side); r = -0.709, p<0.001 (left side)) were noted. The measurements of the total height of the mandibular body and the height from the lower border of mandible to the lower border of the mental foramen do not correlate significantly with dual-energy x-ray absorptiometry measurements and they should not be used as indicators of bone mineral status. The efficacy of the panoramic-based Mandibular Ratio index in diagnosing osteopenia/osteoporosis is low to moderate.
Key words: mandible, tooth loss, alveolar bone loss, bone mineral density, osteoporosis.
