建立QST标准曲线用于非典型性牙痛患者病因机制分类的初步研究

Establishment of a standard QST curve for etiology and mechanism study of atypical odontalgia

目的本研究尝试运用“Z值”转化方法将用于神经源性疼痛检测的定量感觉检查(QST)转化为感觉曲线,用于显示非典型性牙痛(AO)的个体病因分类。方法利用数学“Z值”转化方法,统一QST中不同单位的13个感觉参数的检查结果,使各个刺激形式的结果反映在同一坐标轴内,较之对QST数值结果的统计对比,感觉特征曲线更能清晰地反映患者个体的感觉异常特点。结果成功建立QST标准曲线,用于AO患者的感觉异常比对,可以直观读取患者个体的感觉异常结果,从而直接反应该个体病因分类。结论“Z值”转化方法可为AO的机制分型研究提供有效手段。

Objective To demonstrate a Z-score-based profiles to reflect the most prominent somatosensory changes and classification of atypical odontalgia(AO)patients.Methods Z-transformation on quantitative sensory testing(QST)results were used to demonstrate the sensory changes of AO patients on profiles.Results The Z-score-based profile could reflect somatosensory changes and etiological classification of individual AO patients.Conclusions The Z-transformation transformation method can provide an effective means for the study of AO mechanism typing.
