围更年期女性牙本质敏感症与骨质疏松症的相关性

Relationship between menopausal osteoporosis and the dentine hypersensitivity

目的探讨围更年期女性骨质疏松与牙本质敏感症之间的内在联系,为临床采取相应的措施阻止或延缓疾病的发展进程提供依据。方法选取2013年1月至2014年5月在大庆油田总医院健康体检测试骨密度的45~60岁女性994例,根据中华医学会骨质疏松和骨矿盐疾病分会2011年发布的原发性骨质疏松症诊治指南标准,骨量正常：T值≥-1.0;低骨量：-2.5〈T值〈-1.0;骨质疏松：T值≤-2.5。按照骨密度测定值的高低分为3组：骨量正常组、低骨量组和骨质疏松组,并对各组有无牙敏感,月经情况进行记录整理。结果骨量正常组401例,有牙本质敏感症94例,牙本质敏感症发生率为23.44%;骨量减少组289例,有牙本质敏感症147例,牙本质敏感症发生率为50.87%;骨质疏松组304例,有牙本质敏感症163例,牙本质敏感症发生率为53.61%。骨质疏松组、骨量减少组和骨量正常组牙本质敏感症发生率比较,差异有统计学意义（P=0.005）。结论低骨量组和骨质疏松组的牙本质敏感症发生率明显高于骨量正常组,提示围更年期女性骨质疏松与牙本质敏感症呈正相关。

Objective To explore the relationship between menopausal osteoporosis（ OP） and the dentine hypersensitivity in order to provide objective evidence for doctors to prevent or delay the progress of diseases. Methods 994 women of 45 to 60 years old had been checked by dual-energy X-ray absorptionmetry in our hospital from January 2013 to May 2014. They were divided into three groups including normal,osteopenia and OP according to the Tscores of BMD in accordance with the diagnostic criteria of CSOBMR guideline 2011. The situation of the tooth sensitivity and their menstrual were recorded. Results There were 94 women of tooth sensitivity in 401 normal BMD group. The incidence rate of the tooth sensitivity was 23. 44 %（ 94 /401）; 147 in osteopenia group,the rate was 59. 87 %（ 147 /289）; 163 in OP group,the rate was 53. 61 %（ 163 /304）. The incidences of the tooth sensitivity in these three groups were different（ P = 0. 005）. Conclusion Women in the osteopenia group and the OP group had more tooth sensitivity than normal BMD group. There were positive correlation between OP and the dentine hypersensitivity.
