目的牙科复合材料的成分可以通过聚合反应从牙科填充物中释放出来。本研究的目的是检查与时间相关的洗脱和分解的聚合复合材料使用氘代solvents.Methodelution和分解的成分进行了研究与氘代溶剂甲醇和水通过气相色谱/质谱分析下列复合材料为180天：Filtek™ Supreme XT、Filtek™ Supreme XT Flow、Tetric Ceram®、Tetric Flow®、Grandio®、Grandio®Flow。结果在180天内没有化合物作为分解产物形成。19种化合物被鉴定为洗脱产物：Bis-EMA，TEGDMA，DDDMA，EGDMA，MAA，BPA，CQ，HQME，DMABEE，CSA，BL，TEG，BHT，TINP，TPP，TPSB，DEDHTP，DCHP，对于Tetric Flow®，在第90天在氘代甲醇中测量的Bis-EMA的最高浓度为36.993 mmol/l，并且在第90天在氘代水中也测量的Bis-EMA的最高浓度为0.031 mmol/l。在第60天，在1.322 mmol/l的氘代甲醇中测量了Grandio®Flow的最高TEGDMA浓度，在第3天，在0.689 mmol/l的氘代水中测量了Filtek™ Supreme XT Flow的最高TEGDMA浓度。在第90天，测得Tetric Flow®在氘代甲醇中的最高BPA浓度为1.469 mmol/l。第180天，在氘化水中测得Grandio®的最高BPA浓度为0.007 mmol/l。时间相关洗脱的显著性检查表明，各种洗脱产物（例如Bis-EMA、BPA）在前90天仅少量释放，但在第90天和第180天之间大量释放。
ObjectivesConstituents of dental composites can be released from dental fillings after polymerization. The aim of this study was to examine the time-related elution and breakdown of separable constituents of polymerized composites using deuterated solvents.MethodElution and breakdown of constituents were investigated with deuterated solvents methanol and water by gas chromatography/mass spectrometry of following composites for 180 days: Filtek™ Supreme XT, Filtek™ Supreme XT Flow, Tetric Ceram®, Tetric Flow®, Grandio®, Grandio®Flow.ResultsWithin 180 days no compounds were formed as the products of breakdown. 19 compounds were identified as elution products: Bis-EMA, TEGDMA, DDDMA, EGDMA, MAA, BPA, CQ, HQME, DMABEE, CSA, BL, TEG, BHT, TINP, TPP, TPSB, DEDHTP, DCHP, ß-PHEA.The highest concentration of Bis-EMA was measured for Tetric Flow®in deuterated methanol on day 90 at 36.993 mmol/l and in deuterated water also on day 90 at 0.031 mmol/l.The highest TEGDMA concentrations were measured for Grandio®Flow in deuterated methanol on day 60 at 1.322 mmol/l and for Filtek™ Supreme XT Flow in deuterated water on day 3 at 0.689 mmol/l. The highest BPA concentration was measured for Tetric Flow®in deuterated methanol on day 90 at 1.469 mmol/l. The highest BPA concentration was measured for Grandio®in deuterated water on day 180 at 0.007 mmol/l.Significance Examination of time-related elution indicates that various elution products (e.g. Bis-EMA, BPA) were only released in small quantities during the first 90 days, but in high quantities between day 90 and day 180.
