Seventy-two extracted anterior teeth were subjected to routine biomechanical instrumentation 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% glutaraldehyde, and 1% metronidazole. The roots were split and examined under light microscope as well as SEM. Statistical analysis showed that a combination of hydrogen peroxide with chloramine, chloramine or glutaraldehyde was more effective than saline or hydrogen peroxide in removing the debris.
72颗拔除的前牙接受常规生物力学预备，并分别用六种冲洗液之一进行冲洗：生理盐水、3%过氧化氢、2%氯胺、3%过氧化氢与2%氯胺交替使用、1%戊二醛和1%甲硝唑。将牙根劈开，在光学显微镜和扫描电子显微镜下进行观察。统计分析表明，过氧化氢与氯胺、氯胺或戊二醛联合使用在清除碎屑方面比生理盐水或过氧化氢更有效。
