研究类型:

观察性研究

Study type:

Observational study

研究所处阶段:

回顾性研究 

Study phase:

Retrospective study

研究设计:

横断面 

Study design:

Cross-sectional 

研究目的:

通过回顾性研究,应用阻力分析法建立“牙-骨-根”分类(牙冠阻力、骨阻力、牙根阻力、牙周膜间隙)预测成人下颌第三磨牙拔除难度模型,通过前瞻性研究确认该模型预测拔牙困难程度的敏感度和特异性。  

Objectives of Study:

Through retrospective study, the resistance analysis method was used to establish the "dentist-bone-root" classification model (crown resistance, bone resistance, root resistance, periodontal space) to predict the difficulty of extraction of adult mandibular third molars, and the sensitivity and specificity of this model to predict the difficulty of extraction were confirmed through prospective studies.
