本研究旨在比较三种储存方法对组织修整剂表面粗糙度的影响。本研究中使用了四种市售组织调理剂（GC Soft Liner、Softone、Fictioner和Hydro-Cast）。将每种材料的5个样品储存在蒸馏水、空气和义齿清洁剂（Polident）中。在浸泡0、1、3、7和14天后，使用轮廓仪测量由组织调节剂制成的牙结石模型的平均表面粗糙度（R-a）值。3种保存方法的R-a值差异有统计学意义。除在空气中贮存的材料外，每种贮存方法的R-a值均随浸泡时间的增加而显著增加。结果表明，在空气中贮存的材料表现出最稳定和最低的R-a值。所得结果表明，组织调理剂在空气中储存时，比在蒸馏水和义齿清洁剂中储存时，表面粗糙度表现出平滑和最小的变化。
The purpose of this study was to compare the influence of three kinds of storage methods on surface roughness of tissue conditioners. Four commercial tissue conditioners (GC Soft Liner, Softone, Fictioner, and Hydro-Cast) were used in this study. Five samples of each material were stored in distilled water, air, and a denture cleanser (Polident). Mean surface roughness (R-a) values of dental stone casts made from the tissue conditioners were measured after 0, 1, 3, 7, and 14 days of immersion using a profilometer. Significant differences in the R-a values of the specimens were found among the three storage methods. The values of R-a significantly increased with increase in immersion time for each storage method, except for the materials stored in air. It was found that the materials stored in air showed the most stable and lowest values of R-a. Results obtained suggested that a tissue conditioner exhibited smooth and minimal change in surface roughness with time when stored in air than in distilled water and denture cleanser.
