概括

一种使用459名患者的数据验证的新型牙图准确地预测了牙周炎的10年牙损失风险. 这种基于2018年分类的工具显示了在积极牙周治疗之前进行风险评估的跨站点适用性.

科学领域:

牙周病学牙周病学
牙科公共卫生牙科公共卫生
生物统计学生物统计学

背景情况:

2018年牙周病分类要求外部验证作为风险评估工具.
统计模型的图形表示,即名图,可以帮助预测疾病的进展和结果.

研究的目的:

通过使用名谱,对2018年牙周病分类进行外部验证.
评估诺莫图谱能够预测由于牙周炎造成的10年牙损失风险的能力.

主要方法:

在四个队列 (美国和英国) 中对459名牙周炎患者进行了回顾性分析.
在积极牙周治疗 (APT) 之前,牙周炎的分期和分级.
评估了模型歧视 (AUC-ROC) 和校准 (CITL,校准斜率,E:O比率),并测试了重新校准方法.

主要成果:

原来的名录仪在不良校准下实现了0.72的AUC-ROC.
同位素重新校准将AUC-ROC提高到0.77并增强了校准指标 (E-统计=1.00,CITL=0.00,斜率=1.00).

结论:

从2018年牙周病分类中得出的名谱是一种可行的预后工具.
该工具证明了在工业化国家在APT之前预测10年牙损失风险的跨站点适用性.

Teeth

The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...
