The effect of two different disinfectants on the dimensional stability of two alginate impression materials over five days was investigated. 60 impressions were made under standardised conditions, 30 with each alginate, of which ten were disinfected in each disinfectant and ten were controls. Impressions were stored over a period of five days in a container with 100% humidity. Measurements were made between four points. Two-way analysis of variance indicated no differences in the change from baseline to day 5 between any of the combinations of alginate and disinfectant. Only two of the changes between baseline and day 5 reached statistical significance at the p < 0.01 level. Therefore it can be concluded that within the limitations of this study when newer alginate impression materials are disinfected they remain stable over 5 days.
研究了两种不同消毒剂对两种藻酸盐印模材料在五天内尺寸稳定性的影响。在标准化条件下制作了60个印模,每种藻酸盐制作30个,其中每种消毒剂中对10个印模进行消毒,10个作为对照。印模在湿度为100%的容器中保存五天。在四个点之间进行测量。双向方差分析表明,藻酸盐和消毒剂的任何组合在从基线到第5天的变化中均无差异。从基线到第5天的变化中只有两个在p<0.01水平达到统计学显著性。因此可以得出结论,在本研究的局限性内,当新型藻酸盐印模材料进行消毒时,它们在5天内保持稳定。
