目的：本研究的目的是确定pH值和时间是否有任何影响的吸附和溶解度行为的复合树脂材料存储在缓冲solution.Methods：三个混合的复合修复树脂材料（光谱（TM），Z-100（R））和ArtGlassTM）具有不同的基质结构和填料组成进行了研究。根据ISO 4039生产每种材料的120个样本。材料被储存在McIlvain的缓冲溶液中，在不同的pH值（4，6和8）在1，7，60和180天，pH值进行测量之前和之后完成storage.Results：时间有显着的影响吸附和溶解行为的复合树脂材料测试。材料Z-100（（R））之一显示出取决于溶液pH的显著质量增加和/或减少。材料光谱（TM）的显着影响pH值，导致不同的吸附取决于pH值的solution.Conclusions：时间的存储是重要的吸附和溶解度行为的复合树脂材料测试。在本研究中，其中一种材料的溶解度比较显示，当使用蒸馏水作为储存介质时，其值是先前报告的两倍。溶液中的pH值似乎对复合树脂材料的吸附和溶解行为有影响。的吸附和溶解度行为的时间和pH值的材料测试的敏感性似乎是有关的基质的亲水性和填料的化学组成。(C)2001爱思唯尔科技有限公司版权所有。
Objectives: The aim of this study was to determine whether pH and time has any influence on the sorption and solubility behaviour of composite resin materials stored in a buffer solution.Methods: Three hybrid composite restorative resin materials (Spectrum(TM), Z-100((R)) and ArtGlass'") with different matrix structure and filler composition were studied. One hundred and twenty specimens of each material were produced according to ISO 4039. The materials were stored in McIlvain's buffer solution at different pH (4, 6 and 8) at 1, 7, 60 and 180 days, pH measurements were carried out before and after completed storage.Results: Time had a significant influence on the sorption and solubility behaviour of the composite resin materials tested. One of the materials Z-100((R)) showed a significant mass increase and/or decrease depending on the pH of the solution. The material Spectrum(TM) was significantly influenced by pH, resulting in different sorption depending on the pH of the solution.Conclusions: Time of storage was important for the sorption and solubility behaviour of the composite resin materials tested. Comparison of solubility for one of the materials showed twice as high values in the present study as previously reported when distilled water was used as storage medium. pH in the solution seems to have an influence on the sorption and solubility behaviour of composite resin materials. The sensitivity of the sorption and solubility behaviour to time and pH of the materials tested seems to be related to the hydrophilicity of the matrix and the chemical composition of the filler.
