目的：探讨碱性还原电位水、中性水、酸性氧化电位水对口腔藻酸盐印模三步冲洗消毒的效果，以解决目前口腔印模临床消毒的难题，为临床选择快捷、高效、安全的消毒方法提供依据。方法对符合纳入标准的60例患者，采用统一的标准进行藻酸盐印模的制作，取同一患者上颌左右印模各1副，按随机数字表法分为实验组和对照组各60副印模。实验组采用碱性还原电位水、中性水、酸性氧化电位水三步冲洗法冲洗印模，对照组采用自来水冲洗印模。比较各时点2组藻酸盐印模的消毒效果。结果冲洗藻酸盐印模3、6、9 min 时，2组与自身冲洗前相比菌落数均降低，且相同冲洗时间实验组的菌落数均低于对照组的菌落数，差异均有统计学意义，Z 值分别为-6.160，-6.159，-5.920，P＜0.01；实验组冲洗3、6、9 min 的杀灭率分别为80.29%、92.91%、97.98%，均高于同期对照组的杀灭率，差异均有统计学意义，χ2值分别为13.51，12.11，8.31，P＜0.01。结论用碱性还原电位水、中性水、酸性氧化电位水三步冲洗法对藻酸盐印模冲洗6 min 具有较好的消毒效果，是一种快捷、高效、安全的口腔印模消毒方法。

Objective To evaluate the disinfection effect of alginate impressions using three- step flushing approach with alkaline electrolyzed- oxidizing water (AEOW), neutral water, acidic electrolyzed-reductive water (AERW) in sequence, and therefore explore a convenient, safe and efficient approach for disinfection of impressions. Methods 60 pairs of alginate impressions of left maxillary dentition and right maxillary dentition were taken from 60 patients set the left ones and the right ones into the experimental group and the control group randomly. For the experimental group, the impressions were flushed with AEOW, neutral water and AERW in sequence, for the control group, the impressions were flushed with water. Then the disinfection effect of the two groups at different flushing time was compared. Results The number of bacterial on the alginate impressions was reduced in both groups at 3, 6 and 9 minutes. The number of bacterial of the experimental group was lower than that of the control group at the same time point, the differences were statistically significant,Z values were -6.160, -6.159, -5.920 respectively, P<0.01. The disinfection effect of the three- step flushing approach was 80.29%, 92.91%, 97.98% at 3, 6 and 9 minutes respectively. The killing rate of the experimental group was higher than that of the control group at the same time,the differences were statistically significant, χ2 values were 13.51, 12.11, 8.31 respectively, P<0.01. Conclusions The disinfection effect of the three - step flushing approach for 6 minutes can reach a satisfactory level. Hence, the three- step flushing approach is a convenient, safe, and efficient approach for disinfection of impressions.
