The smear layer removal capability of different instrumentation techniques on the mesio-buccal root canals of maxillary first molars is of interest to dentists. Sixty extracted maxillary first molars with fully developed apices, curved root canals, and curvatures between 30 to 45 degrees were selected. The teeth were divided into four groups (n=15) based on the instrumentation technique used. The samples were analyzed using a thermal field emission scanning electron microscope to assess smear layer removal at the apical, middle, and coronal thirds of the canals. The Wave One file system showed superior performance in smear layer removal across all three regions of the canal compared to hand files, Hyflex CM rotary files and SAF.
不同器械预备技术对上颌第一磨牙近中颊根根管的玷污层去除能力是牙医们感兴趣的。选取了60颗根尖完全发育、根管弯曲且弯曲度在30至45度之间的拔除上颌第一磨牙。根据所使用的器械预备技术将牙齿分为四组（n = 15）。使用热场发射扫描电子显微镜对样本进行分析，以评估根管根尖、中部和冠部三分之一处的玷污层去除情况。与手动锉、Hyflex CM旋转锉和SAF相比，Wave One锉系统在根管的所有三个区域的玷污层去除方面表现出卓越性能。
