| 内容記述 | The purposes of this study were to investigate the water uptake characteristics, color change and Shore-A hardness of new kinds of addition-silicone-based soft liners and two another commercial silicone based soft liners. Seven specimens were made using specially constructed plaster molds. Water sorption measurements were determined gravimetrically at 37℃ in distilled water and were compared after 1 day and 14 days. Color changes were evaluated on specimens that were stored in testing solutions (saline, instant coffee and olive oil mix with β-carotene). The color was measured with a Spectrophotometer CM 1000 and hardness was evaluated using a Durometer Shore-A hardness instrument DD 2-A. These measurements were done after 1, 2, 3, 4 and 12 weeks, with the materials stored in temperature controlled water bath at 37℃. Mean values and standard deviations were calculated for each experiment and material. The water sorption was compared statistically with a Student's t-test for each material and compared statistically with a one-way analysis of variance and Student's t-test. Bartlett's test for homogeneity of variance was applied to the data for color change and hardness, and multiple comparisons using Tukey's test were performed. For the new developed addition-silicone-based soft liners, the water uptake was quite small as the days, and color change was also quite small in three solutions. Severe color change was observed in instant coffee and olive oil mix for another two commercial soft liners. In the hardness test, there were no significant differences from 1 week to 12 weeks in each solution for the new materials. Although water uptake was limited, color changes were observed in the two commercialized materials, particularly with the instant coffee and oil mix. Among several factors responsible for color change, staining characteristics of the surrounding medium seems to be the most important factor for the observed color change. Hardness was increased in fluoride contained soft liners. The novel silicone soft liners tested in this study are available for clinical use. | |||||||
