背景
在牙周炎患者中，需要定量的预后评估，以便做出关于保留牙齿或拔除牙齿并用牙齿假体替换的循证决定。
方法
198名在1989年或1990年接受积极牙周治疗并平均遵守支持性牙周治疗11.8+/-2.3年的患者被纳入研究。建立广义线性模型，并通过广义估计方程进行拟合，以识别SPT过程中牙齿缺失的预测因素。
结果
在基线存在的4559颗牙齿中，166颗(3.6%)在积极治疗期间拔除，249颗(5.5%)在SPT期间拔除。糖尿病(OR=4.17)、牙槽骨密度降低(OR=1.04)、牙齿活动性增加(III：OR=5.52)、多发性牙根(OR=1.82)和无生命牙髓(OR=2.24)是SPT期间牙齿丢失的显著预测因素(P<；0.05)。基于这些参数，建立了一个预后模型，该模型提供了牙周治疗时牙齿存活概率的估计。
结论
运用多元分析方法，建立了一个对临床决策有价值的预后模型。
BACKGROUND
In patients with periodontitis, a quantitative prognostic assessment is needed in order to make evidence-based decisions about retaining teeth or extracting and replacing them with a dental prosthesis.
METHODS
One hundred and ninety eight patients receiving active periodontal treatment in 1989 or 1990 and complying with supportive periodontal therapy (SPT) over an average of 11.8+/-2.3 years were included in the study. A generalized linear model was established and fitted via generalized estimating equations to identify predictors for tooth loss during SPT.
RESULTS
Of the 4559 teeth present at baseline, 166 (3.6%) were extracted during active treatment and 249 (5.5%) during SPT. Baseline findings of diabetes mellitus (OR=4.17), reduced alveolar bone levels (OR=1.04 for each 1% increment), increased tooth mobility (III versus 0: OR=5.52), multiple roots (OR=1.82), and non-vital pulp (OR=2.24) were significant (p<0.05) predictors for tooth loss during SPT. Based on these parameters, a prognostic model was constructed that provides estimates of tooth survival probability when periodontal therapy is rendered.
CONCLUSION
Using a multivariate approach, a prognostic model was developed that may be of value for clinical decision making.
