摘要

目的:使用传统触觉技术、放射线造影技术、牙尖定位器估算牙齿的工作长度,并通过锥形束计算机断层扫描技术确认工作长度:研究对象包括 40 名年龄在 20 至 50 岁之间的不可逆牙髓炎患者。术前拍片后开始手术。在需要的情况下使用复合材料制作洞壁,然后使用橡胶坝。使用锥形束计算机断层扫描测量中颊面和中舌面牙管的工作长度,并将其视为标准值。然后使用触觉法,用放射线照相软件测量牙槽骨长度,再用顶点定位仪测量:结果:与触觉法和放射显像法相比,顶点定位仪显示出最佳结果:顶点定位仪的测量值与锥形束计算机断层扫描的工作长度测量值最为接近,电子顶点定位仪可作为工作长度测定的替代方法有效使用。根据工作长度测定的等级,各种技术的质量依次为:锥形束计算机断层扫描(CBCT)> Apexloc > 放射显像(RVG)> 触觉。因此,可以使用 Apex 定位器替代锥形束计算机断层扫描来确定工作长度。

Evaluation of Different Techniques of Working Length Determination in Comparison with CBCT.

Aim: To estimate the working length of teeth using conventional tactile technique, radiovisiography technique, Apex locator, and confirmation of working length by cone beam computed tomography technique.

Materials and methods: Forty patients with the age group between 20 and 50 years with irreversible pulpitis were included in this study. After taking a preoperative radiograph, the procedure was started. The cavity wall buildup was done using composite in the cases needed and then rubber dam application was done. The working length of mesiobuccal and mesiolingual canal was taken using cone beam computed tomography and this was considered as the standard value. Then using tactile method, length of the canal was measured using radiovisiographic software followed by apexlocator.

Result: The Apex locator has showed best result as compared to tactile and radiovisiography.

Conclusion: Apex locator values were closest to cone beam computed tomography working length measurement values and electronic apexlocator can be used efficiently as an alternative method for working length determination. The quality of various techniques according to ranks of working length determination was found to be Cone beam computed tomography (CBCT) > Apexloc > Radiovisiography (RVG) > Tactile. Thus, Apex locator can be used as an alternative to cone beam computed tomography for working length determination.
