摘要
目的：该研究旨在通过使用五种不同的技术了解下颌磨牙中中管的发生率：选取 150 颗拔出的下颌第一磨牙，拍摄锥形束计算机断层扫描（CBCT）图像。然后，在牙科放大镜（3 倍）下制作传统的取穴，并在牙科手术显微镜（DOM）（6 倍）下检查。在所有这些阶段都注意到了中间管的发生率。之后，对这些牙齿进行清髓法检查，并记录这一阶段的发生率并进行比较：CBCT（9 毫米）的总体诊断准确率为 97.48%，在 DOM 下进行评估的总体准确率为 97.33%。结论：这项研究提倡使用新的诊断方法：本研究提倡使用 CBCT 和 DOM 等新方法来发现和检查这些附属管道。
Identification of Middle Mesial Canal in Mandibular Molars Using Five Different Techniques: An In vitro Study.
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.
