目的:本研究旨在研究机械和化学清洁对硅胶软衬里材料表面粗糙度的影响。方法:我们选择具有最高(软)和最低(超软)肖氏 A 硬度的硅胶软衬里材料。在磨损测试中,使用厨房海绵(Sponge)、软刷(Soft Brush)或硬刷(Hard Brush)将样本清洗50,000次,或将其存放在水中(无清洗)。在浸泡试验中,将样本浸泡在水(Water)、中性过氧化物假牙清洁剂(Neutral)、碱性过氧化物假牙清洁剂(Alkaline)或次氯酸盐假牙清洁剂(Hypochlorite)中1440小时。在试验前后测量表面粗糙度的算术平均高度(Sa)和最大高度(Sz)。使用 Kruskal-Wallis 和 Mann-Whitney U 测试对数据进行分析。结果:在磨损测试中,使用软衬里材料观察到 Sa 和 Sz 存在显着差异,但对于免清洁和海绵则没有观察到显着差异。在浸泡测试中,观察到软衬里材料的 Sa 和 Sz 存在显着差异,但在水和中性或水和碱性之间没有显着差异。除了 Sa 的水和中性或水和碱性之间以及 Sz 的水和中性之间之外,使用 Supersoft 观察到显着差异。结论:使用海绵进行机械清洁不会增加具有高肖氏 A 硬度的材料的表面粗糙度。此外,中性过氧化物义齿清洁剂不会增加高和低肖氏 A 硬度材料的粗糙度。© 2019 日本修复协会。由爱思唯尔有限公司出版。保留所有权利。
Purpose: This study aims to investigate the effect of mechanical and chemical cleaning on the surface roughness of silicone soft relining materials.Methods: We selected silicone soft relining materials with the highest (Soft) and lowest (Supersoft) Shore A hardness. In the abrasion test, specimens were cleaned 50,000 times using a kitchen sponge (Sponge), a soft (Soft brush) or hard (Hard brush) denture brush, or stored in water (No cleaning). In the immersion test, specimens were immersed in either water (Water), neutral peroxide denture cleanser (Neutral), alkaline peroxide denture cleanser (Alkaline), or hypochlorite denture cleanser (Hypochlorite) for 1440 h. Surface roughness of the arithmetic mean height of the surface (Sa) and maximum height (Sz) were measured before and after the tests. Data were analyzed using the Kruskal–Wallis and Mann–Whitney U tests.Results: In the abrasion test, significant differences were observed for Sa and Sz with Soft relining materials, but not for No cleaning and Sponge. In the immersion test, significant differences were observed for Sa and Sz with Soft relining materials, but not between Water and Neutral or Water and Alkaline. Significant differences were observed with Supersoft, except between Water and Neutral or Water and Alkaline for Sa and between Water and Neutral for Sz. Conclusions: Mechanical cleaning using a sponge did not increase the surface roughness of the material with a high Shore A hardness. Furthermore, neutral peroxide denture cleanser did not increase the roughness of materials with high and low Shore A hardness.© 2019 Japan Prosthodontic Society. Published by Elsevier Ltd.
