简介：激光激活冲洗，以消除有机碎片从运河峡部进行了调查，使用x射线微焦点计算机断层成像。方法：14颗离体下颌磨牙。使用标准化器械方案准备近中根管。两组（n = 7）使用标准针头冲洗（SNI）或光子诱导光声流（PIPS）进行最终冲洗。在将根管扩大至301.06后，通过灌注前后的微型计算机断层扫描重建根管体积，以通过叠加体积的定量分析评估有机组织和无机碎片的去除。使用双因素方差分析和Tukey方法进行体积比较，认为统计学差异在α = 0.05水平具有显著性。结果：激光激活的PIPS组在根管系统体积的增加和碎屑清除方面优于激光激活的PIPS组（P
Introduction: Laser-activated irrigation to remove organic debris from canal isthmuses was investigated using x-ray microfocus computed tomographic imaging. Methods: A total of 14 extracted human mandibular molars were used. The mesial canals were prepared using a standardized instrumentation protocol. Two groups (n = 7) underwent final irrigation using either standard needle irrigation (SNI) or photon-induced photoacoustic streaming (PIPS). After enlarging canals to 301.06, canal volumes were reconstructed from micro computed tomographic scans before and after irrigation to assess removal of organic tissue and inorganic debris by quantitative analysis of the superimposed volumes. Comparisons of the volumes were made using 2-way analysis of variance and Tukey method, with statistical differences considered significant at the alpha = 0.05 level. Results: Debris removal and an increase in root canal system volume for the laser-activated PIPS group was more significant (P
