氢氧化钙（CH）用于改善根管消毒在大多数根管再治疗。本研究旨在分析使用7种不同根管预备锉（K锉、预弯K锉、EndoActivator、超声锉、预弯超声锉、F锉和单独针冲洗）进行根尖运输的CH去除效果。在根管充填前7天，建立有无根尖移位的弯曲根管模型。上述七种技术被用于其去除。然后将根部拆卸并拍摄数码照片。使用图像分析仪image pro plus 6.0计算整个根管表面中残留CH的比率。采用单因素方差分析和事后Tukey检验分析数据。结果表明，除单纯冲洗外，6种机械方法均能有效清除CH（P <0.05）。在弯曲根管中，EndoActivator、预弯超声锉和F锉对根尖移位的根管预备效果优于其他4种根管预备（P <0.001），而EndoActivator、预弯超声锉和F锉对根尖移位的根管预备效果无显著性差异（P> 0.05）。有根尖移位的根管中CH残留率高于无根尖移位的根管（P <0.05）。总之，CH很难完全去除。根管与根尖运输将导致不充分的CH清除。EndoActivator、预弯超声锉和F锉对根尖移动的弯曲根管的治疗效果更好。
Calcium hydroxide (CH) is applied to improve disinfection of root canals in most root canal retreatment. This study aimed to analyze the CH removal efficacy using 7 different root preparing files (K file, pre-curved K file, EndoActivator, Ultrasonic file, pre-curved ultrasonic file, F file and needle irrigation alone) with apical transportation. Standardized models of curved canal with such apical transportation or not were set up before applying CH to root canal for 7 days. Seven techniques described above were used for its removal. Then the roots were disassembled and digital photos were taken. The ratio of residual CH in the overall canal surface was calculated using the image analyzer image pro plus 6.0. The data were analyzed using one-way ANOVA with post hoc Tukey test. Results revealed that CH was effectively removed (P<0.05) by using all 6 mechanical methods except irrigation alone. In curved root canals with apical transportation, EndoActivator, pre-curved ultrasonic file and F file were found to be more effective in removing CH than the other four file (P<0.001), while there was no significant difference among EndoActivator, pre-curved ultrasonic file and F file groups (P>0.05). The percentage of residual CH in the canal with apical transportation was higher than that in the canal without apical transportation (P<0.05). In conclusion, CH can be hardly removed completely. Canal with apical transportation will result in insufficient CH removal. EndoActivator, pre-curved ultrasonic file and F file are more effective in the curved root canal with apical transportation.
