摘要
目的:评价用两种消毒液直接调拌藻酸盐印模材对印模尺寸稳定性有无影响。方法:分别用蒸馏水、0.2%的次氯酸钠和0.1%的洗必泰调拌藻酸盐印模材,对同一试件制取20组印模,以蒸馏水调拌者为对照组。用超硬石膏灌模,40min脱模静置24h测量模型三维标志点的长度再进行统计学分析。结果:试验组和对照组模型三维标志点长度无显著性差异。结论:0.2%的次氯酸钠或0.1%的洗必泰直接调拌藻酸盐印模材进行印模消毒不影响印模尺寸稳定性,可用于口腔科印模消毒。
Objective： To evaluate the dimensional stability of alginate impression made from alginate material mixed with two sorts of disinfectants. Methods： 20 groups of alginate material impression of the custom model were made, mixed with distilled water, 0.2% NaClo and 0. ,1% hibitane, respectively. The distilled water group acted as the control The dental stone was poured into the impressions and the casts were got 40 minutes later. The dimensional signs of the casts were measured after 24 hours and the data were analyzed statistically. Results： The measurements between test group and control group showed no statistical difference. Conclusion： The disinfection method of mixing alginate material with 0.2% NaClo or 0.1% hibitane directly doesnl influence the accuracy of the impression.
