摘要： [摘要] 目的：评价旋转式和往复式两种刷洗方式对E-max热压铸瓷、Ceramage聚合瓷、纳米树脂这三种美容修复材料所造成的影响。方法：制备E-max热压铸瓷、Ceramage聚合瓷、纳米树脂试件各12片，按照不同的刷洗方式分成两组，在室温下用自制的电动牙刷刷洗装置，以牙膏浆为磨损介质，对三组试样分别进行刷洗，每个试样刷洗时间为194.6 min，刷洗力度为200 N，刷洗后采用单因素方差分析计算实验前后三种试件的重量损失、粗糙度变化值和色彩改变值。结果：两种方式刷洗时，树脂组和聚合瓷组重量均有损失 (P <0.05)，其中树脂组＞聚合瓷组＞热压铸瓷组；其中纳米树脂重量损失为旋转组＞往复式组。粗糙度值的变化，旋转式刷洗聚合瓷组和树脂组无明显变化，E-max组粗糙度值增加(P <0.05)，往复式刷洗造成三组材料的粗糙度值均呈现增加的趋势，其中热压铸瓷组最大，树脂与聚合瓷的变化两者之间无明显差异；实验前后树脂组的色差值最大(P <0.05)，Ceramage聚合瓷其次，E-max无明显变化，两种刷洗方式间均无明显差异。结论：电动刷洗会造成树脂材料和聚合瓷的重量损失和颜色改变，引起热压铸瓷的表面粗糙度值的增加。旋转式刷洗对树脂材料的磨损要大于往复式刷洗，往复式刷洗造成三种材料的粗糙度值均增加，两种方式对材料颜色变化无差异。

Abstract: [Abstract] Objective：Study of effects of rotary and reciprocating scrubbing methods on three cosmetic repair materials: E-max heat-pressed ceramic, Ceramage polymer-ceramic, nano-resins. Methods：12 specimens were made out of E-max heat-pressed ceramic, Ceramage polymer-ceramic, and nano-resin seperately. The specimens were divided into two subgroups according to different scrubbing methods. At room temperature, use self-made electric toothbrush brushing device，and a tube of tooth paste as wear medium to scrub the specimens in three kinds of materials. Each specimen was brushed for 194.6min, and the brushing force was 200 N. Weight loss, roughness and color change of three kinds of specimens were calculated before and after scrub. The results were analyzed by one-way ANOVA. Results：With the two scrubbing methods, the resin group and the polymer ceramic group both had weight loss (P <0.05). The weight loss of the resin group was more than that of the polymer ceramic group. In the nano resin group, weight loss of rotating scrub subgroup was more than that of reciprocating brush subgroup. As for changes in roughness value, rotary scrub polymer ceramic group and resin group had no significant changes. The E-max group had increase in roughness value(P <0.05). Besides, roughness value of the three groups of materials showed an increasing trend with reciprocating scrub method, among which the heat-pressed ceramic group increased most and there was no significant difference in the roughness changes between resin and polymer ceramic materials. The resin group had the biggest color changes before and after the experiment (P <0.05), Ceramage polymer ceramic came the second, and E-max group had no significant color change. There was significant difference of color changes between the resin group and E-max group(P<0.05) Conclusions：Electric brushing can cause weight loss and color changes of resin and polymer ceramic, cause increase in surface roughness values of heat-pressed ceramic. Rotary brush causes greater wear of the resin than reciprocating scrub, and reciprocating scrub causes increase in roughness values of the three kinds of materials. The two methods make no difference in color change of materials.
