本纵向队列研究的目标是检查依据临床附着丧失(CAL)的线性混合模型(LMM)定义的牙周炎进展位点 和受试者的牙周疾病进展模式。

本纵向队列研究的目标是检查依据临床附着丧失(CAL)的线性混合模型(LMM)定义的牙周炎进展位点 和受试者的牙周疾病进展模式。

材料和方法:共有113名牙周健康和302名牙周炎患者,每两个月检测一次CAL,为期12个月。 LMMs适合每个位点,预测的CAL水平用于分类他们的疾病进展状态。参与者根据进展位点的数量分为不变,过渡和活跃的样本。使用描述性统计学来探讨牙周疾病进展的模式。

结果:进展主要发生在磨牙(进展部位的50%)和近中位点(72%),影响深的位点比例较高(2.7%比0.7%),牙周袋是进展的主要模式(49% )。我们发现LMM和传统方法确定疾病进展情况之间的一致性(47%)较低,例如CAL≥3mm的变化。 14%的受试者被列为活动受试者,其中93%受试者患有牙周炎。活动受试者的年平均进展率为0.35mm/y。

结论:基于LMM定义的进展位点和受试者呈现类似于文献中先前报道的疾病进展模式。
