绝经妇女全身骨密度与慢性牙周炎的关系探讨

Postmenopausal women body bone mineral density and the relationship between chronic periodontitis

目的探讨绝经妇女全身骨含量(BMC)、骨密度(BMD)与慢性牙周炎的关系。方法选择绝经妇女220例,其中慢性牙周炎组162例,对照组58例。采用双能X线骨密度测量仪测量全身BMC、BMD值,根据慢性牙周炎的诊断标准,将诊断为牙周健康者及轻、中、重度慢性牙周炎进行统计分析。结果绝经期妇女慢性牙周炎患者全身BMC、BMD水平显著低于对照组(P<0.01),轻度慢性牙周炎组>中度慢性牙周炎组>重度慢性牙周炎组,三组间差异均有统计学意义(P<0.01)。低骨量、骨质疏松发生率与慢性牙周炎严重程度有密切关系,轻、中、重度慢性牙周炎各组间比较差异均有统计学意义(P<0.01)。结论绝经妇女中,牙周炎的发生发展与全身BMC、BMD减少和骨质疏松症有关。

Objective To study the postmenopausal women total body bone mineral content （BMC） and bone mineral density （BMD） and the relationship of chronic periodontitis. Methods 220 cases of postmenopausal women were involved, including 162 ea- ses of chronic periodontitis as experimental group, 58 cases as control group. The total body BMC and BMD values were measured u- sing dual-energy X-ray absorptiometry measurement instrument, according to the diagnostic criteria of chronic periodontitis. The data of periodontal healthy subjects as well as light, medium and severe chronic periodontitis patients were analyzed. Results The menopaus- al women with chronic periodontitis total body BMC and BMD were significantly lower than control group （ P 〈 0.01 ）. Mild chronic pe- riodontitis group 〉 moderate chronic periodontitis group 〉 severe chronic periodontitis group, had significant difference between the three groups （P 〈0.01 ）. Low bone mass, the incidence of osteoporosis has close relationship with severity of chronic periodontitis, light, medium and severe chronic periodontitis is compared between each group with significant difference （P 〈0.01 ）. Conclusion The occurrence/development of periodontitis and body BMC and BMD loss related to osteoporosis in postmenopausal women.
