牙周附着丧失与骨密度关系的研究

Relationship between periodontal attachment loss and bone mineral density

目的探讨健康藏族成年妇女骨密度状态与牙周附着丧失的关系。方法随机选择35～69岁健康藏族成年妇女（无牙周疾病治疗史）141人，检查牙周组织状态，确定牙周附着丧失牙数及缺失牙数。问卷调查排除全身疾病和服用影响骨代谢药物史。并用MetriScan TM（美国Alara公司提供）指骨骨密度仪进行骨密度测量，采用单因素方差分析方法进行统计学分析。结果每一年龄段内，牙周附着丧失不同状态下妇女的骨密度在统计学上没有显著差异，但随着年龄增高，牙周附着丧失及缺失牙严重程度增加。结论骨密度减低是牙周附着丧失的危险因子。

Objective To observe the relationship between periodontal attachment loss and bone mineral density in healthy Tibetan women. Methods One hundred and forty-one healthy Tibetan women aged 35～69, without history of periodontal therapy, were recruited randomly and the status of periodontal tissue was examined to determine the number of teeth with periodontal attachment loss and the number of teeth loss. Questionnaires about general health were completed by the subjects to exclude systemic diseases and history of taking medicines that affect metabolism of bone tissue. The MetriScan from Alara Company was used to measure the middle part of 2nd, 3rd and 4th fingers to obtain the mean value of BMD. The ANOVA statistics method was used to analysis the data. Results There was no obvious statistical significance of BMD between different status of periodontal attachment loss groups in the same age group, but the severe degree of periodontal attachment loss and teeth loss increased with advancing age. Conclusions Decreased bone density is a risk factor for periodontal attachment loss.
