组织调理剂的临床效果受其凝胶化特性和凝胶化后的粘弹性性质的影响。本研究的目的是评估添加乙醇（EtOH）对这些性能的影响，并比较EtOH与粉/液（P/L）比的影响。本研究中使用了三种组织调节剂。用振荡流变仪获得凝胶化时间。凝胶化后的粘弹性也通过应力松弛试验进行了评价。添加更大量的乙醇产生更短的凝胶化时间和更大的流动后凝胶化。相反，虽然使用较高的P/L比产生较短的凝胶化时间，但该程序导致凝胶化后的较小流动。结果表明，在组织调理剂的液体中加入乙醇是控制凝胶化时间和凝胶化后粘弹性能的有效方法。
The clinical effectiveness of tissue conditioners is influenced by their gelation characteristics and viscoelastic properties after gelation. The purpose of this study was to evaluate the effect of addition of ethyl alcohol (EtOH) on these properties, and to compare the effect of EtOH with that of the powder/liquid (P/L) ratio. Three tissue conditioners were used in this study. The gelation times were obtained with an oscillating rheometer. The viscoelastic properties after gelation were also evaluated by stress relaxation tests. Addition of greater amounts of EtOH produced the shorter gelation time and the larger flow after gelation. Conversely, although the use of a higher P/L ratio produced a shorter gelation time, this procedure leads to a smaller flow after gelation. The results suggested that the addition of EtOH to the liquids of tissue conditioners is an effective method for controlling gelation times and viscoelastic properties after gelation.
