目的:研究RootZX根尖定位仪的临床应用价值。方法:选择拟行根管治疗的患者60例、92颗后磨牙共283条根管,根据牙位的左右把就诊患者随机分成两组:定位仪组和定位仪加插针组,用RootZX根尖定位仪确定根管工作长度后进行常规根备、根充,由4位高年资主治医师独立阅片,记录每条根管的根充效果:恰填、超填或欠填。结果:定位仪组和定位仪加插针组恰填分别为127例、108例,超填为28例、12例,欠填为5例、3例,两组根管充填效果差异无统计学意义(P>0.05)。结论:RootZX根尖定位仪可快速地为临床工作提供准确的根管工作长度。
Objective: To study the clinical value of RootZX apex locator. Methods: Sixty patients with root canals and 28 root canal patients with 92 posterior teeth were selected. The patients were randomly divided into two groups according to the position of the tooth: the locator group, the locator plus the needle group, and RootZX root Apex locator to determine the length of the root canal after conventional root preparation, root filling, physicians by the 4 senior physician independent reading, record root canal root canal filling effect: just fill, fill or under fill. Results: There were 127 cases, 108 cases, 28 cases of over-filling, 12 cases of under-filling, 5 cases of under-filling and 3 cases of filling. The difference between the two groups was no statistically significant Significance (P> 0.05). Conclusion: The RootZX Apex Locator can quickly provide accurate root canal length for clinical work.
