To compare the accuracy of radiovisiography (RVG), Root ZX mini Apex locator, and Endo radar's inbuilt Apex Locator during working length determination determination in primary teeth with the actual/direct canal length.
58 primary teeth indicated for extraction in children of age group 4-12 years were selected. RVG, Root ZX mini Apex Locator, and Endo radar's Apex Locator were used to determine the working length intraorally. Following extraction of the teeth, the actual working length was determined with magnifying loupes (2.5×) using a K-file and an endodontic ruler. The data was tabulated and statistically analyzed.
84 canals (58 teeth) were evaluated and Root ZX mini Electronic Apex Locator (EAL) showed no statistically significant difference with the actual measurement ( = 0.18) whereas Endo radar and RVG showed statistically significant difference. Endo radar underestimated, while RVG overestimated the working length. The most accurate method for working length measurements of the root canals in primary teeth was Root ZX mini EAL, followed by Endo radar and the least accurate was RVG.
The Root ZX mini Apex Locator showed the most promising results and had an excellent degree of agreement with actual working length, followed by Endo radar and RVG.

比较放射成像（RVG）、Root ZX迷你根尖定位仪和Endo radar内置根尖定位仪在确定乳牙工作长度时与实际/直接根管长度的准确性。
选取4 - 12岁儿童中58颗需拔除的乳牙。使用RVG、Root ZX迷你根尖定位仪和Endo radar根尖定位仪在口内确定工作长度。牙齿拔除后，使用放大倍数为2.5倍的放大镜、K锉和根管测量尺确定实际工作长度。将数据列表并进行统计分析。
共评估了84个根管（58颗牙齿），Root ZX迷你电子根尖定位仪（EAL）与实际测量值相比无统计学显著差异（P = 0.18），而Endo radar和RVG有统计学显著差异。Endo radar低估了工作长度，而RVG高估了工作长度。乳牙根管工作长度测量最准确的方法是Root ZX迷你EAL，其次是Endo radar，最不准确的是RVG。
Root ZX迷你根尖定位仪显示出最有前景的结果，与实际工作长度的一致性极佳，其次是Endo radar和RVG。
