目标.漂白处理可影响组分从常规复合材料中的释放。在这项持续的研究中，研究了两种不同的漂白凝胶对散装填充复合组分洗脱的影响。将复合材料Tetric EvoCeram Bulk Fill、QuiXFilTM和X-tra fil用漂白凝胶Opalescence PF 15%（PF 15%）处理5小时和PF 35%（PF 35%）处理30分钟，然后在甲醇和水中储存24小时和7天。通过气相色谱/质谱（GC/MS）分析洗脱液。未漂白标本作为对照组。共7个不同的洗脱物质已被确定从漂白处理后的研究复合材料。其中三种是甲基丙烯酸酯：甲基丙烯酸2-羟乙酯（HEMA）、二甲基丙烯酸三乙二醇酯（TEGDMA）和三甲基丙烷三甲基丙烯酸酯（TMPTMA）。与未漂白的对照相比，发现在PF 15%处理后以下化合物的洗脱增加：HEMA（Tetric EvoCeram（R）Bulk Fill）、TEGDMA（QuiXFilTM，X-tra fil）和4-N，N-二甲基氨基苯甲酸丁基乙氧基酯（DMABEE）（Tetric EvoCeram（R）Bulk Fill，QuiXFilTM，X-tra fil）。与对照相比，以下化合物在PF 35%处理后显示出洗脱减少：TEGDMA（QuiXFilTM）和DMABEE（Tetric EvoCeram（R）Bulk Fill）。HEMA的最高浓度为0.22 mmol/l（Tetric EvoCeram（R）Bulk Fill，甲醇，7 d，PF 15%），TEGDMA的最高浓度为0.3 mmol/l（X-tra fil，水，7 d，PF 15%），DMABEE的最高浓度为0.05 mmol/l（QuiXFil（TM），水，7 d，PF 35%）。与未漂白的散装填充复合材料相比，PF 15%和PF 35%可导致某些散装填充组分的洗脱减少和/或增加。(C)2015年牙科材料学院。由爱思唯尔有限公司出版。保留所有权利。
Objectives. Bleaching treatments can affect release of components from conventional composites. In this continuing study the influence of two different bleaching gels on the elution of bulk-fill composite components was investigated.Methods. The composites Tetric EvoCeram (R) Bulk Fill, QuiXFil (TM) and X-tra fil were treated with the bleaching gels Opalescence PF 15% (PF 15%) for 5 h and PF 35% (PF 35%) for 30 min and then stored in methanol and water for 24 h and 7d. The eluates were analyzed by gas chromatography/mass spectrometry (GC/MS). Unbleached specimens were used as control group.Results. A total of 7 different elutable substances have been identified from the investigated composites after bleaching-treatment. Three of them were methacrylates: 2-hydroxyethyl methacrylate (HEMA), triethylene glycol dimethacrylate (TEGDMA) and trimethylolpropane trimethacrylate (TMPTMA). Compared to the unbleached controls an increase in elution after PF 15%-treatment of following compounds was found: HEMA (Tetric EvoCeram (R) Bulk Fill), TEGDMA (QuiXFil (TM), X-tra fil) and 4-N,N-dimethylaminobenzoic acid butyl ethoxy ester (DMABEE) (Tetric EvoCeram (R) Bulk Fill, QuiXFil (TM), X-tra fil). Following compounds showed a reduction in elution after PF 35%-treatment compared to controls: TEGDMA (QuiXFil (TM)) and DMABEE (Tetric EvoCeram (R) Bulk Fill). The highest concentration of HEMA was 0.22 mmol/l (Tetric EvoCeram (R) Bulk Fill, methanol, 7d, PF 15%), the highest concentration of TEGDMA was 0.3 mmol/l (X-tra fil, water, 7d, PF 15%) and the highest concentration of DMABEE was 0.05 mmol/l (QuiXFil (TM), water, 7d, PF 35%).Significance. PF 15% and PF 35% can lead to reduced and/or increased elution of some bulk-fill components, compared to unbleached bulk-fill composites. (C) 2015 Academy of Dental Materials.
