目的：观察体外模拟刷牙对复合树脂表面粗糙度的影响。方法：选择3个厂家生产的5种复合树脂制作试样，并即刻抛光，分别在体外模拟刷牙前、后检测表面粗糙度Ra值。结果：（1）抛光即刻和体外模拟刷牙后，大颗粒填料复合树脂（Quixfil）表现为较高的表面粗糙度；（2）钡玻璃填料复合树脂（AP-X ，Quixfil）在体外模拟刷牙后表面粗糙度显著增加（ P＜0．05）；（3）石英填料复合树脂（P60，P90）和纳米填料复合树脂（Z350）体外模拟刷牙后表面粗糙度无显著变化，（P＞0．05）。结论：（1）复合树脂的填料种类、粒度、工艺影响表面粗糙度；（2）石英及纳米工艺填料树脂能够较好的抵抗体外模拟刷牙，表面粗糙度稳定；（3）Silorane基质复合树脂P90表面光滑程度较好，不易受到体外模拟刷牙的影响。

Objective :To evaluate in vitro simulated toothbrushing on surface roughness of composite resin materials . Methods :5 commercial resin composites with different filler and matrix were studied in this study .Ra values were test-ed by surface profilometer before and after simulated toothbrushing .Results:(1) Surface roughness of Quixfil with large glass fillers was the greatest before and after the brushing process .(2) Ra values of composites with larger glass filler (AP-X ,Quixfil) increased significantly after brushing process (P< 0 .05);(3)Ra value did not significantly changed on composite resins with quartz and nano fillers (P>0 .05) .Conclusion:(1) Factors like filler component ,par-ticle size and technique can influent the surface roughness of composite .(2) Composites with quartz and nano fillers were resistant to the toothbrushing process and the roughness were stable .(3) Surface roughness of silorane based composites (P90) were acceptable and were not influenced by the toothbrushing process .
