The polymerization shrinkage of a number of commercially available composite resin (Starfiil, Durafill, VLC-1 and GD) and an experimental composite #1 which contains 16% DMSOC (a new monomer which expands on polymerization) has been determined using a water-filled dialometer. The results indicated that GD displayed the largest shrinkage value at 2.62 +/- 0.20%, while VLC-1, Durafill and Staifill had smaller values at 2.10 +/- 0.10%, 1.84 +/- 0.20% and 1.42 +/- 0.16%, respectively. The experimental composite. #1 underwent least contraction during setting (0.14 +/- 0.13%). The polymerization shrinkage was influenced by the filler loading and the duration of the exposure to the activating light source. There was little influence of shade of materials on the polymerization shrinkage for VLC-1.
使用充满水的膨胀仪测定了多种市售复合树脂（Starfiil、Durafill、VLC - 1和GD）以及一种含有16%DMSOC（一种在聚合时会膨胀的新型单体）的实验性复合树脂#1的聚合收缩率。结果表明，GD的收缩率最大，为2.62±0.20%，而VLC - 1、Durafill和Staifill的收缩率较小，分别为2.10±0.10%、1.84±0.20%和1.42±0.16%。实验性复合树脂#1在固化过程中收缩最小（0.14±0.13%）。聚合收缩率受填料含量和暴露于活化光源的持续时间影响。材料的色泽对VLC - 1的聚合收缩率影响很小。
