AIM
The purpose of the study was to find out the incidence of the middle mesial canal in mandibular molars by using five different techniques.
MATERIALS AND METHODS
A total of 150 extracted human mandibular first molars were selected, and cone beam computed tomography (CBCT) images were taken. Then, conventional access cavities were made, followed by troughing under dental loupes (3X), and were also examined under a dental operating microscope (DOM) (6X). Incidence of intermediate canals was noted from all these stages. Later, these teeth underwent a clearing method procedure, and incidence was noted from this stage and compared.
RESULTS
The overall diagnostic accuracy of CBCT (9 mm) had 97.48%, and evaluation under DOM had an overall accuracy of 97.33%. The least accuracy was found with the naked eye (92.67%).
CONCLUSION
This study advocates the usage of newer methods like CBCT and DOM to find out and negotiate these accessory canals.
目的
本研究的目的是通过使用五种不同技术来找出下颌磨牙中近中根管的发生率。
材料与方法
共选取150颗拔除的人类下颌第一磨牙，拍摄锥形束计算机断层扫描（CBCT）图像。然后，制作传统的开髓洞形，接着在牙科放大镜（3倍）下进行槽沟制备，并在牙科手术显微镜（DOM）（6倍）下进行检查。记录所有这些阶段中间根管的发生率。之后，这些牙齿进行了清理方法程序，并记录该阶段的发生率并进行比较。
结果
CBCT（9毫米）的总体诊断准确率为97.
