目的探讨TRR1根尖定位仪在不同牙髓活力状态下测量根管长度的准确性.方法由指定的临床主治医师使用TRR1根尖定位仪对诊断为牙髓炎和尖周炎的两组患牙分别作根管长度测量,根据X线插针定位片测定K锉尖距根尖的距离(L),以0 mm≤L≤2 mm为测量准确.结果牙髓炎组(A组)测量准确率较根尖周炎组(B组)低,但两组准确率无显著性差异.结论 TRR1根尖定位仪的准确性不受牙髓活力状态的影响.

Objective To investigate the influence of pulp status on the accuracy of determining root canal length by TRR1 electronic apex locator in clinic.Methods Two hundred and fifty-seven root canals of 87 teeth were divided into two groups, teeth in group A were diagnosed as pulpitis, and teeth in group B were apical periodontitis. All these root canals' working length were measured by TRR1 electronic apex locator, then measured the distance between the K-file tip and the radiographs(L), when 0 mm≤L≤2 mm,the data were considered accuracy. Results The accuracy rate of group A was lower than that of group B, but there was no significant difference in these data between two groups. Conclusion The accuracy of TRR1 electronic apex locator wasn't influenced by the pulp status in this study.
