Relationship between Bone Mineral Densities of Cervical and Lumbar Vertebrae in Postmenopausal Women

Abstract

For dental implant treatment, it is important to assess the general bone condition. Using multi-slice CT scans, we assessed the relationships between the bone mineral densities (BMDs) of the cervical and lumbar vertebrae in postmenopausal women to see if such data might be useful for imaging-based diagnosis prior to dental implant treatment. Thirty postmenopausal women were enrolled in this investigation, and their third cervical vertebrae were scanned for BMD using multi-slice computed tomography (CT) while the lumbar vertebrae were measured using dual energy X-ray absorptiometry, after which the percentage of the young adult mean (YAM) was calculated. The correlations between the BMD of the cervical vertebra and percentage of YAM were analyzed. The mean BMD of the cervical vertebra was 255 mg/cm 3 HA (s. : 35.9) in the osteoporosis group. A significant difference was observed between the normal and osteoporosis groups, and between the osteopenic and osteoporosis groups. A correlation (r = 0.705) was observed between the BMD of the cervical vertebrae and percentage of YAM of the lumbar vertebrae. The BMD of the third cervical vertebrae obtained from multi-slice CT images might be applicable in dental implant treatment to evaluate the influence of the general bone condition.

Mandibular Cortical Bone Index Using Multi-Slice and Cone-Beam Computed Tomography

“…Correlation coefficients between BMDs of the lumbar vertebrae and values using quantitative ultrasound densitometry ranged from 0.433 to 0.640 10) . In previous studies, the BMD of the third cervical vertebra and MCI-MSCT were proposed to evaluate the influence of the general bone condition in imaging diagnosis for dental implant treatment using multi-slice CT 6,7) . Celenk and Celenk reported that the relationship between the age and CT values of the fifth cervical vertebra was negatively correlated (r = 0.354) in the total subjects, with 68 men and 46 women, using a linear equation (y=-2.06x+485.86) 11) .…”

“…CT analysis of the head and neck region was performed to investigate the area of the lesion and determine the extent of resection. Regions of interest with a 0.597 cm 2 area were set in the body of the third cervical vertebra, as previously described [ 24 ]. The CT values were averaged, and the mean CT value was transformed into the bone mineral density (BMD).…”

“…The data on BMDs of the lumbar vertebrae (L2, 3, and 4) measured using DXA (Norland XR36, Fisher BioMedical Inc., Venice, FL) and reported in our previous study 11) were used. The mean period between multislice CT scans and DXA for the lumbar vertebrae was 0.7 years (s.d.…”
