INTRODUCTION
Electronic apex locators are among the most acceptable instruments for determining root canal length The present study aimed to evaluate the effect of long service life on the accuracy of the Dentaport Root ZX (DP ZX) electronic apex locator (EAL).
MATERIALS AND METHODS
In this study, fifty single-rooted freshly extracted human teeth were used. After determining the root canal length with a K-file and a dental operative microscope, the canals were measured with four separate DP ZX apex locators (two with more than 6 years of life service while two others had less than 6 years of life service). Data were analyzed by repeated ANOVA measurement.
RESULTS
No significant difference was found between the EALs with different years of life services (=0.62). All EALs could determine root canal length with high accuracy of more than 94%.
CONCLUSION
Based on the results of this study, the long service life had no significant impact on the accuracy of DP ZX EALs in terms of root canal length determination.
引言
电子根尖定位仪是确定根管长度最常用的器械之一。本研究旨在评估长时间使用对登士柏Root ZX（DP ZX）电子根尖定位仪（EAL）准确性的影响。
材料与方法
本研究使用了50颗新鲜拔除的单根人牙。在用K锉和牙科手术显微镜确定根管长度后，使用四台不同的DP ZX根尖定位仪测量根管（两台使用年限超过6年，另外两台使用年限少于6年）。数据采用重复方差分析测量进行分析。
结果
不同使用年限的EAL之间未发现显著差异（P = 0.62）。所有EAL都能以超过94%的高精度确定根管长度。
结论
基于本研究结果，就根管长度测定而言，长时间使用对DP ZX EAL的准确性没有显著影响。
