Rods of a visible-light-cured dental composite resin were photo-polymerized and immersed in water at 37 degrees C for 7 days. The residual monomers (TEGDMA and Bis-GMA) trapped in the set composite and those eluted into water were analysed by gas-liquid chromatography. It became evident that minor amounts of the residual monomers dissolved in water, but that most residual monomers remained in the set composite. Extension of the irradiation period contributed to the significant reduction in the residual monomer level and its elution into water.
将可见光固化牙科复合树脂棒进行光聚合，然后在37摄氏度的水中浸泡7天。采用气液色谱法分析固化复合材料中截留的残留单体（TEGDMA和Bis-GMA）以及洗脱到水中的残留单体。结果表明，少量残留单体溶解于水中，但大多数残留单体仍留在固化的复合材料中。延长辐照时间有助于显著降低残留单体水平及其向水中的洗脱量。
