The working length determination is necessary before root canal shaping, chemical cleaning, disinfection, and obturation in pulpectomy of primary dentition. This study aimed to evaluate the accuracy of Wirele-X and compare it with DentaPort ZX and Woodpex III in primary molar teeth.
The in vitro study was performed by using 30 extracted primary mandibular molar teeth. In distal roots, the actual working length was determined by taking forward a #10 K-type canal file under a dental operating microscope with 10x magnification. Each tooth and lip clip were embedded in alginate before determining the working lengths using electronic apex locators. The average of three electronic working lengths was calculated for each sample, and the actual working length was subtracted from the electronic working length.
There were no significant differences in the accuracy rate of DentaPort ZX, Wirele-X, and Woodpex III in the determination of the working length set at ± 0.5 mm and ± 1 mm, respectively (P > 0.05).
This study reported that DentaPort ZX, Wirele-X, and Woodpex III can be safely used in the pulpectomy of primary molars. Wirele-X can provide an advantage in working length determination in children because of its wireless feature.
在乳牙牙髓摘除术中，根管预备、化学清理、消毒和充填之前确定工作长度是必要的。本研究旨在评估Wirele-X的准确性，并将其与DentaPort ZX和Woodpex III在乳磨牙中的准确性进行比较。
采用30颗拔除的下颌乳磨牙进行体外研究。在远中根管中，在10倍放大的牙科手术显微镜下向前推进#10 K型根管锉来确定实际工作长度。在使用电子根尖定位仪确定工作长度之前，将每颗牙齿和唇夹嵌入藻酸盐中。计算每个样本三个电子工作长度的平均值，并从电子工作长度中减去实际工作长度。
DentaPort ZX、Wirele-X和Woodpex III在分别设定为±0.5 mm和±1 mm的工作长度测定中的准确率无显著差异（P>0.05）。
本研究报告称，DentaPort ZX、Wirele-X和Woodpex III可安全用于乳磨牙的牙髓摘除术。Wirele-X因其无线特性，在儿童工作长度测定中具有优势。
