■电子顶点定位器(EAL)经常用作工作长度(WL)测定中X射线照片的佐剂。集成的根尖定位器(IAL)的引入通过在根管成形时连续监测根尖来进一步简化了根管治疗。
■本研究的目的是评估X光片的疗效,EAL,和IAL在存在各种灌溉物的情况下确定WL。
■本体内研究是对30例患者进行的,每组10例,根据使用的冲洗剂的类型;0.9%盐水(第1组),0.2%氯己定(第2组),和2.5%的次氯酸钠(NaOCL)(第3组)。在每一组中,使用常规射线照片测定WL,根ZX迷你(EAL),和CanalProCL2i(IAL)。
■Kruskal-Wallis检验和Friedman的双向ANOVA检验用于统计分析。
■根ZXMini的平均WL相对较低,而CanalProCL2i的WL和射线照相方法具有可比性。在所有方法中,使用的溶液类型不影响WL,当NaOCL用作冲洗剂时,平均WL较高。然而,上述比较无统计学意义.
■本研究中采用的灌溉溶液对顶点定位器和射线照片的性能没有影响。
UNASSIGNED: Electronic apex locators (EALs) are frequently used as adjuvant to radiographs in working length (WL) determination. The introduction of integrated apex locators (IALs) further simplified the root canal treatment by continuous monitoring of the apex while root canal shaping.
UNASSIGNED: The aim of this study was to evaluate the efficacy of radiographs, EAL, and IAL in determining the WL in the presence of various irrigants.
UNASSIGNED: The present in vivo study was carried out on 30 patients who were divided into 10 in each group, based on the type of irrigant used; 0.9% saline (Group 1), 0.2% chlorhexidine (Group 2), and 2.5% of sodium hypochlorite (NaOCL) (Group 3). In each group, WL is determined using conventional radiographs, Root ZX Mini (EAL), and CanalPro CL2i (IAL).
UNASSIGNED: Kruskal-Wallis test and Friedman\'s two-way ANOVA test were used for statistical analysis.
UNASSIGNED: Mean WL was comparably lower with Root ZX Mini, while the WL by CanalPro CL2i and the radiographic method were comparable. In all methods, the type of solutions used did not influence the WL, with a higher mean WL when NaOCL is used as an irrigant. Nevertheless, the above comparisons were not statistically significant.
UNASSIGNED: the irrigation solutions employed in this study had no impact on the performance of apex locators and radiographs.
