背景：全景x线片上的下颌骨下皮质侵蚀可能有助于识别低骨密度（BMD）或骨质疏松症的绝经后妇女。本研究的目的是评估训练有素的普通牙科医生（GDPs）是否可以在其诊所通过全景x线片识别未被发现的低骨骼骨密度和脊柱骨折的绝经后妇女。方法：2004年6月至12月，455名50岁及以上的妇女到22个受过培训的国内生产总值（gdp）的牙科诊所就诊，并进行了牙科疾病的全身性x线评估，其中168名绝经后妇女根据皮质侵蚀的结果被诊断为骨骼骨密度低。在这些女性中，39名年龄在50-84岁（平均年龄（SD，标准差），64.8（7.4）岁），以前没有骨质疏松症诊断的女性参加了这项研究。采用双能x线骨密度仪（DXA）测量腰椎和股骨颈的骨密度。通过DXA评估时获得的侧位x线片评估脊柱骨折。结果：骨密度正常2例（5.1%）（骨密度t评分为0 ~ 1.0），骨质减少21例（53.9%）（骨密度t评分为-2.5 ~ -1.0），骨质疏松16例（41.0%）（骨密度t评分< -2.5）。8名女性（20.5%）在胸椎、腰椎或两者均有骨折。结论：我们的研究结果表明，基于训练有素的gdp对其全景x线片的分析，可以识别出高比例的绝经后妇女未被发现的低骨骼骨密度和脊柱骨折。
Background: An eroded inferior cortex of the mandible on panoramic radiographs may be useful for identifying post-menopausal women with low bone mineral density (BMD), or osteoporosis. The purpose of this study was to assess whether trained general dental practitioners (GDPs) can identify post-menopausal women with undetected low skeletal BMD as well as spinal fractures by panoramic radiographs in their clinics.Methods: Out of 455 women aged 50 years and older who visited the dental clinics of 22 trained GDPs and had panoramic radiographic assessment for the examination of dental diseases between June and December 2004, 168 post-menopausal women were diagnosed as having low skeletal BMD based on cortical erosion findings. Of these women, 39 women aged 50-84 years (mean age (SD, standard deviation), 64.8 (7.4) years) with no previous diagnosis of osteoporosis participated in this study. BMD at the lumbar spine and femoral neck was measured using dual energy X-ray absorptiometry (DXA). Spine fractures were assessed on lateral radiographs obtained at the time of the DXA assessment.Results: Two women (5.1%) had normal BMD (BMD T-score > -1.0), 21 women (53.9%) had osteopenia (BMD T-score of -2.5 to -1.0) and 16 women (41.0%) had osteoporosis (BMD T-score < -2.5). Eight women (20.5%) had fractures at the thoracic spine, lumbar spine, or both.Conclusions: Our results suggest that a high percentage of post-menopausal women with undetected low skeletal BMD as well as spinal fractures may be identified based on trained GDPs' analyses of their panoramic radiographs.
