摘要 目的观察牙髓状态对Root ZX根尖定位仪测定根管长度的准确性有无影响。方法收集临床须行根管治疗的患牙94例,共156个根管,使用Root ZX确定工作长度,预备根管后拍主尖片验证工作长度的测定是否准确,统计分析活髓牙组和死髓牙组准确率有无差异。结果在活髓牙和死髓牙的根管预备中,利用Root ZX测定根管工作长度的准确率差异无统计学意义(P>0.05)。结论牙髓活力对根管长度测量仪准确性无显著影响。 Objective To observe the accuracy of working length determination by Root ZX in the teeth with different pulp vitality.Methods 94 cases requiring root canal therapy(156 root canals)were prepared and the working length(WL) was determined by Root ZX.Master gutta percha points were inserted into the canals and radiographs were taken to observe whether the WL determination was accurate.And the statistical analysis was performed.Results The difference of accuracy in WL determination by Root ZX between the teeth with different pulp vitality was not significant(P0.05).Conclusion The accuracy of Root ZX working in different pulp vitality is not adversely affected.
