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.
