摘　　要：目的:评估根管测量仪运用于牙根纵裂患者早期诊断过程中的意义。方法:对2018年2月~2019年11月在本院诊断及治疗的20例牙根纵裂早期患者(30颗患牙)实施数值样本调查,均开展X射线牙片检测、锥形束CT检测、根管测量仪检测,并予以对应治疗干预,计算不同检测方式对牙根纵裂的检出患牙颗数占比率、对牙根纵裂的诊断准确占比率。结果:根管测量仪检测方式、锥形束CT检测方式对牙根纵裂的检出患牙颗数占比率、对牙根纵裂的诊断准确占比率对比X射线牙片检测方式增加(P<0.05),根管测量仪检测方式对牙根纵裂的检出患牙颗数占比率、对牙根纵裂的诊断准确占比率对比锥形束CT检测方式区别不高(P>0.05)。结论:在牙根纵裂患者早期诊断过程中采取根管测量仪诊断的准确性较高。Objective:To evaluate the significance of using the root canal measuring instrument in the early diagnosis of the patients with longitudinal root fracture.Methods:From February 2018 to November 2019,20 patients(30 teeth)diagnosed and treated in our hospital in the early stage of diastematomyelia were investigated with numerical samples.X-ray dental film test,cone beam CT test and root canal measuring instrument were carried out,and corresponding treatment interventions were given to calculate the proportion of the number of teeth detected and the accurate proportion of the diagnosis of diastemyelia rate.Results:The ratio of root canal measuring instrument detection method,cone beam CT detection method to the detection of longitudinal root fractures and the accuracy of the diagnosis of longitudinal root root fractures increased compared with X-ray dental film detection methods(P<0.05)),the detection method of the root canal measuring instrument has no significant difference in the proportion of the number of teeth with longitudinal root fractures and the accuracy of the diagnosis of longitudinal root fractures compared with cone beam CT detection methods(P>0.05).Conclusion:The accuracy of root canal measuring instrument is high in the early diagnosis of the patients with longitudinal root fracture.
