ObjectivesThis study examined toothbrush/toothbrush abrasion of a photo-activated prosthetic composite（dentin and enamel variations）for evaluating the impact of polymerization sources on abrasive wear.MethodsA photo-activated prosthetic composite material（Artglass）was assessed.牙本质和牙釉质的变化聚合使用专有的光固化单元与两个氙频闪灯（UniXS），和其他牙釉质标本聚合与实验室光固化单元与三个荧光灯管或与高强度的单元与两个金属卤化物灯。将所有样本在水中储存14天，并使用研磨浆料（高露洁Fluoriguard）和牙刷（Oral-B 40）进行牙刷/牙刷磨损（350 g垂直负荷）。通过轮廓仪测定20，000次冲击后试样的垂直损失量和表面粗糙度。使用方差分析（ANOVA）和Sheffe's S间隔比较5个样本组的平均值结果用自制装置聚合时，牙釉质材料的磨损和表面粗糙度的平均值分别为34.08μm牙本质材料的平均直径分别为42.02 μ m（±5.62）和1.23μm（±0.20）。刷牙后釉质材料的磨损和表面粗糙度均显著小于牙本质材料。与金属卤化物单元聚合的试样的磨损所需的平均值为23.89μm（±6.17），并表现出最小的wear.ConclusionsThe使用高强度的金属卤化物光固化单元有效地提高了复合材料的耐磨性。为了达到光滑和耐磨的效果，装饰物的表面应覆盖搪瓷材料。
ObjectivesThis study examined toothbrush/dentifrice abrasion of a photo-activated prosthetic composite (dentin and enamel variations) for the purpose of evaluating the influence of polymerization sources on abrasive wear.MethodsA photo-activated prosthetic composite material (Artglass) was assessed. Dentin and enamel variations were polymerized using a proprietary photo-curing unit with two xenon stroboscopic lamps (UniXS), and other enamel specimens were polymerized either with a laboratory photo-curing unit with three fluorescent tubes or with a high intensity unit with two metal halide lamps. All specimens were stored in water for 14days and subjected to toothbrush/dentifrice abrasion (350g vertical load) using an abrasive slurry (Colgate Fluoriguard) and a toothbrush (Oral-B 40). The amount of vertical loss and the surface roughness of the specimens after 20,000 strokes were determined by profilometer. Average values of groups of five specimens were compared using analysis of variance (ANOVA) and Sheffe's S intervals (p<0.05).ResultsWhen polymerizing with the proprietary unit, the abrasion and surface roughness of the enamel material required respective means of 34.08μm (±3.66) and 1.00μm (±0.08), and the those of the dentin material required means of 42.02μm (±5.62) and 1.23μm (±0.20). Both abrasion and surface roughness after toothbrushing of the enamel material were significantly smaller than were those of the dentin material. The abrasion of specimens polymerized with the metal halide unit required a mean of 23.89μm (±6.17) and demonstrated minimal wear.ConclusionsThe use of a high intensity metal halide photo-curing unit effectively enhanced the abrasion resistance of the composite. Surfaces of restorations should be covered with the enamel material in order to achieve smoothness and wear resistance.
