The effects of three dissolving agents on the accuracy of an electronic apex locator- (EAL-) integrated endodontic handpiece during retreatment procedures were evaluated. The true lengths (TLs) of 56 extracted incisor teeth were determined visually. Twenty teeth were filled with gutta-percha and a resin-based sealer (group A), 20 with gutta-percha and a zinc oxide/eugenol-based sealer (group B), and 16 roots were used as the control group (group C). All roots were prepared to TL. Guttasolv, Resosolv, and Endosolv E were used as the dissolving solutions. Two evaluations of the handpiece were performed: the apical accuracy during the auto reverse function (ARL) and the apex locator function (EL) alone. The ARL function of the handpiece gave acceptable results. There were significant differences between the EL mode measurements and the TL (P < 0.05). In these comparisons, Tri Auto ZX EL mode measurements were significantly shorter than those of the TL.
评估了三种溶解剂对再治疗过程中电子根尖定位仪（EAL）集成牙髓手机准确性的影响。通过目视确定了56颗拔除切牙的实际长度（TL）。20颗牙齿用牙胶和树脂基封闭剂充填（A组），20颗用牙胶和氧化锌/丁香酚基封闭剂充填（B组），16颗牙根用作对照组（C组）。所有牙根均预备至实际长度。使用Guttasolv、Resosolv和Endosolv E作为溶解溶液。对手机进行了两项评估：自动反转功能（ARL）期间的根尖准确性和单独的根尖定位仪功能（EL）。手机的ARL功能给出了可接受的结果。EL模式测量值与实际长度之间存在显著差异（P < 0.05）。在这些比较中，Tri Auto ZX EL模式测量值明显短于实际长度测量值。
