本微计算机断层扫描 (Micro-CT) 分析的目的是比较根尖三分之一处的闭塞质量与热垂直压实 (WVC) 和单匹配锥形尺寸圆锥 (SMTSC) 技术。使用 16 颗新拔下颌第一磨牙的近中根（总共 32 个根管）。每个近中牙根的根管均成形为 F3 Protaper 尺寸，并随机分配至连续波垂直压实或单一匹配锥形尺寸锥体技术。使用微型 CT 扫描在距根尖 1、3 和 5 毫米处测量封闭根中的空隙和间隙的体积。使用 WVC 和 SMTSC 技术填充的 1mm (p>0.05)、3mm (p>0.05) 和 5mm (p>0.05) 处测得的空隙体积没有统计学上的显着差异。使用 WVC 和 SMTSC 技术对根尖三分之一处的闭塞质量具有可比性。扫描 38:352-356, 2016。(c) 2015 Wiley periodicals, Inc.
The aim of the present micro-computed tomography (Micro-CT) analysis was to compare the quality of obturation in the apical third of the root with the warm vertical compaction (WVC) and single matching taper sized cone (SMTSC) techniques. Mesial roots of 16 freshly extracted mandibular first molar teeth (with a total of 32 canals) were used. Canals in each mesial root were shaped to a size F3 Protaper and were randomly assigned to either continuous wave vertical compaction or single match tapered size cone technique. Volume of voids and gaps in the obturated roots were measured using micro-CT scanning at 1, 3, and 5mm from the apex of the root. There was no statistically significant difference in the volume of voids measured at 1mm (p>0.05), 3mm (p>0.05) and 5mm (p>0.05) filled with either WVC and SMTSC techniques. The quality of obturation in the apical third of the root with the WVC and SMTSC techniques is comparable. SCANNING 38:352-356, 2016. (c) 2015 Wiley Periodicals, Inc.
