Data suggest that postmenopausal women with osteoporosis are at an increased risk for periodontal attachment loss and tooth loss; however, the extent of relationship between these two diseases is still not clear.
The aim of the study was to evaluate the correlation of periodontal status and bone mineral density (BMD) in postmenopausal women.
The study population included 60 postmenopausal women aged 50-60 years (mean±SD: 55.5±3.4 years). Periodontal status was examined by plaque index, bleeding index, probing depth, and clinical attachment level (CAL). Digital panoramic radiograph was taken to measure the maxillary and mandibular alveolar bone density values. Skeletal (calcaneal) BMD was measured by quantitative ultrasound technique for T-score values. The recorded data for T-score, maxillary and mandibular alveolar bone densities, and periodontal status were subjected to statistical analysis for correlation and regression procedures.
The results showed that mandibular alveolar (r=0.907, P<0.001) and maxillary alveolar bone density (r=0.898, P<0.001) had significant positive correlation with calcaneal T-score. Probing depth (r=-0.316, P<0.05), bleeding index (r=-0.277, P<0.05), and plaque index (r=-0.285, P<0.05) showed weak but significant negative correlation with calcaneal T-score and alveolar bone density of both the jaws, whereas CAL showed weak correlation with T-score which could not reach to a statistically significance level (r=-0.221, P>0.05).
Calcaneal BMD was related to alveolar bone loss and, to a lesser extent, to clinical attachment loss, implicating postmenopausal bone loss as a risk indicator for periodontal disease in postmenopausal women.
数据表明，患有骨质疏松症的绝经后女性发生牙周附着丧失和牙齿脱落的风险增加；然而，这两种疾病之间的关联程度仍不明确。
本研究旨在评估绝经后女性牙周状况与骨密度（BMD）之间的相关性。
研究人群包括60名年龄在50 - 60岁之间的绝经后女性（平均±标准差：55.5±3.4岁）。通过菌斑指数、出血指数、探诊深度和临床附着水平（CAL）检查牙周状况。拍摄数字化全景X线片以测量上颌和下颌牙槽骨密度值。采用定量超声技术测量跟骨骨密度以获取T值。对记录的T值、上颌和下颌牙槽骨密度以及牙周状况数据进行相关性和回归分析的统计分析。
结果显示，下颌牙槽骨（r = 0.907，P < 0.001）和上颌牙槽骨密度（r = 0.898，P < 0.001）与跟骨T值呈显著正相关。探诊深度（r = -0.316，P < 0.05）、出血指数（r = -0.277，P < 0.05）和菌斑指数（r = -0.285，P < 0.05）与跟骨T值以及上下颌牙槽骨密度呈弱但显著的负相关，而CAL与T值呈弱相关，未达到统计学显著水平（r = -0.221，P > 0.05）。
跟骨骨密度与牙槽骨丧失有关，在较小程度上与临床附着丧失有关，这表明绝经后骨质流失是绝经后女性牙周疾病的一个风险指标。
