为了评估和比较根端表面上的牙微裂.
为了评估使用碳化 (TCB),钻涂层超声波尖端 (DUT) 和手术 (SS) 造成的裂.
使用扫描电子显微镜 (SEM) 进行详细的裂分析.

主要方法:

使用了60个经过内牙治疗的人类狗牙.
根据切除仪器 (TCB,DUT,SS) 将牙随机分配到三个组.
进行了根端切除,并通过SEM检查表面以分类微裂.

主要成果:

仪器类型显著影响了牙微裂的形成.
手术 (SS) 组表现出完全裂的发生率最高.
钻石涂层超声波尖端 (DUT) 组显示出完全裂的发生率最低.

结论:

钻石涂层超声波尖端 (DUT) 可能是最好的,以尽量减少牙微裂在apicoectomy.
选择合适的仪器和采用标准化的技术可以减少阳性损伤.
这项研究有助于优化微手术选择的根端准备.

Electron Microscope Tomography and Single-particle Reconstruction

Transmission electron microscopy (TEM) can be used to determine the 3D structure of biological samples with the help of techniques such as electron microscope tomography and single-particle reconstruction. While single-particle reconstruction can examine macromolecules and macromolecular complexes in vitro conditions only, tomography permits the study of cell components or small cells in vivo.
