Tooth-level prognostic systems are valuable tools for treatment planning and risk assessment of periodontally involved teeth. Recently the Miller‒McEntire prognosis index was found to outperform comparable systems. However, it had some limitations. The present study aimed to develop and evaluate the prognostic performance of a modified version that addresses most limitations of the previous model called the periodontal risk score (PRS).

牙周风险评分：6,762 颗牙齿的启动和模型验证

牙齿水平的预后系统是牙周牙齿治疗计划和风险评估的宝贵工具。最近发现 Miller-McEntire 预后​​指数优于同类系统。然而，它有一些局限性。本研究旨在开发和评估修改版本的预后性能，该版本解决了先前模型（称为牙周风险评分（PRS））的大多数局限性。
