摘要

ÖZ目的:在现代牙科中占有重要地位的粘接体系会影响树脂复合修复体的最终颜色特性。因此,本研究的目的是评估当前粘合剂体系对树脂复合材料的颜色,颜色稳定性和半透明性的影响。方法:制备50个圆盘状微杂化树脂复合材料标本。树脂复合椎间盘按粘接剂系统随机分为5组,其中对照组(n=10) (Clearfil Protect Bond、Adper EasyOne、Clearfil QuickBond和Tokuyama BondForce)。使用临床分光光度计进行颜色和半透明测量,在基线时,在粘合剂系统应用后立即进行测量,并在水中浸泡30天后进行测量。统计学分析采用配对样本t检验、单因素方差分析(ANOVA)和Tukey事后比较(p<0.05)。结果:胶粘剂的应用显著改变了树脂复合椎间盘的颜色(E*),与胶粘剂的品牌无关。树脂复合盘在水中保存30天后,对照组的颜色发生了显著变化。Adper EasyOne组和Clearfil Protect Bond组在老化后的颜色值有显著差异。圆盘表面用600、800、1200 - 1500粒度的碳化硅纸进行水冷却抛光。为了区分标本的底部和顶部,在复合圆盘的底部边缘用牙钉做了小切口。用数字卡尺测量树脂复合盘的最终厚度(1.2±0.1)。树脂复合光盘保存在黑色的瓶子里,直到颜色测量完成。结论:粘接剂系统可能会影响修复体的最终颜色,但本研究中测试的粘接剂系统在基线和老化后都会产生临床可接受的变色。

Influence of Current Adhesive Systems on Color Stability of Resin Composite
ÖZ Objective: The adhesive systems which have an important place in modern dentistry can affect the color properties of final resin composite restorations. Therefore, the aim of the present study is to evaluate the influence of current adhesive systems on color, color stability and translucency of resin composites. Methods: Fifty disc-shaped microhybrid resin composite specimens were prepared. Resin composite discs were divided into five groups randomly according to adhesive system including a control group (n=10) (Clearfil Protect Bond, Adper EasyOne, Clearfil QuickBond and Tokuyama BondForce). Color and translucency measurements were performed with a clinical spectrophotometer at baseline, immediately after adhesive system application and after immersion in water for 30 days. For statistical analysis, paired-samples t-test, one-way analysis of variance (ANOVA) and Tukey’s post-hoc comparisons were used (p<0.05). Results: The adhesive application significantly changed the color (E*) of the resin composite discs regardless of the adhesive brand. Storage of the resin composite discs in water for 30 days caused significant color changes in the control group. Significant differences were found in color values of the Adper EasyOne and Clearfil Protect Bond groups after aging. surfaces of the discs were polished with 600-, 800-, 1,200-1,500-grit silicon carbide papers under water cooling. For distinction of the bottom and top sides of specimens, little notches were made with a dental bur on the edge of the bottom side of the composite discs. Final thicknesses of resin composite disks were measured by a digital caliper (1.2±0.1). Resin composite discs were kept in black bottles until color measurements were done. space by Conclusion: The adhesive systems may influence the final color of the restoration, however the adhesive systems tested in the study caused clinically acceptable discoloration at baseline and after aging.
