Abstract
Aim: The aim of this study was to evaluate the clinical reproducibility in determining the working length of Tri Auto ZX2 electronic foraminal locator (EFL) with instruments activated in OGP function by comparing the results obtained by this new device with those obtained by Root ZX II EFL.
Methodology: One hundred twenty-five teeth (72 vital and 60 non-vital pulps) were measured by Root ZX II EFL and Tri Auto ZX2 with instruments activated in OGP function to determine their respective working length, which was defined as a zero reading on the EFL. The instrument length was fixed with a rubber stop and measured with a caliper to an accuracy of 0.1 mm. The values obtained by Root ZX II and Tri Auto ZX2 were statistically compared by student t test with 5% of significance. The agreement between the different devices were determined in percentage. The statistical correlation was also used to determine the agreement between the two EFLs.
Results: There were no significant differences between tested EFLs measurements at “0.0” in vital, non-vital and in the overall analysis (P>0.05). Considering the agreement between devices, the results revealed 98.66% and 100% of concordant values in vital and non-vital pulps, respectively. The R2 coefficient obtained was close to 1 in cases of vital pulp, non-vital pulp and in overall analysis, denoting a strong agreement between the EFLs.
Conclusions: The clinical reproducibility of Tri Auto ZX2 was confirmed when compared to Root ZX II, indicating that the new device is effective for clinical use.
目的:本研究的目的是通过比较Tri Auto ZX2电子椎间孔定位仪(EFL)与Root ZX II EFL测定OGP功能激活仪器测定工作长度的结果,评价其临床可重复性。方法:用Root ZX II EFL和Tri Auto ZX2测量125颗牙齿(72颗重要牙髓和60颗非重要牙髓),仪器在OGP功能下激活,以确定它们各自的工作长度,在EFL上定义为零读数。仪器长度用橡胶止水带固定,用卡尺测量,精度为0.1毫米。Root ZX II与Tri Auto ZX2所得值经学生t检验比较,差异有统计学意义(5%)。不同装置之间的一致性以百分比确定。统计相关性也被用来确定两个efl之间的一致性。结果:在生命值、非生命值和整体分析中,被测efl值在“0.0”时差异无统计学意义(P>0.05)。考虑到设备之间的一致性,结果显示重要和非重要纸浆的一致性值分别为98.66%和100%。在存活牙髓、非存活牙髓和整体分析中,得到的R2系数接近1,表明efl之间的一致性很强。结论:与Root ZX II相比,Tri Auto ZX2具有良好的临床重复性,可用于临床。
