Mean alveolar bone crest height decrement in subjects with an osteoporosis risk

[摘要] People 40-75 years of age have an osteoporosis risk that may be signaled by a decrease in alveolar bone crest height. Thus, this measure can be used as an indicator of osteoporosis risk. This study was conducted to provide a database of decreased alveolar bone crest heights in ages at risk of osteoporosis by using intraoral radiographs. Forty periapical radiographs of the posterior region of tooth 36 (or 46) were measured twice at different times by two different observers. The interproximal decrease in alveolar bone crest height was measured from the alveolar bone crest to the cementoenamel junction (CEJ) for each tooth on the mesial and distal sides using a ruler (mm). The mean decrease in alveolar bone crest height in at-risk ages for osteoporosis was 3.50±1.085 mm, with a mean of 3.15±0.864 mm for those 45-59 years of age, and 3.90±1.156 mm for those aged 60-75 years. The mean decrease in alveolar bone crest height in people 60-75 years of age was larger than in people 45-59 years of age. There was a medium correlation between age and decreased alveolar bone crest height.
