摘　　要：本文以六组冲洗剂对72例离体前牙行根管预备。通过光镜及扫锚电镜观察、评分,结果显示3％过氧化氢与2％氯亚明交替应用、氯亚明、1％戊二醛的清洁作用优于生理盐水及过氧化氢。Seventy-two extracted anterior teeth were subjected to routine biomechanical dedridemont and irrigated with one of the six irrigation liquids:normal saline, 3% hydrogen peroxide, 2% chloramine, 3% hydrogen peroxide and 2% chloramine by turns, 1% glutaradehyde, and 1% metronidazole. 10-minute later, the roots were splited and examined under light microscope as well as SEM. Statistical analysis showed that a combination of hydrogen peroxide with chloramine, chloramine or glutaradehyde was more effective than saline or hydrogen peroxide in removing the debris.
