Abstract

BACKGROUND

This study aimed to analyze and compare the translucency and marginal adaptation of five resin-based materials used as occlusal sealants, both before and after simultaneous fatigue and thermocycling. Two null hypotheses were tested: (1) All tested materials allow the transillumination of sealed occlusal carious lesions. (2) There are no differences in marginal adaptation before and after simultaneous fatigue and thermocycling.

METHODS

Forty extracted human molars with early occlusal caries lesions were randomly divided into five equal groups. Near-infrared transillumination images of cleaned occlusal surfaces were captured before and after applying the following sealants: (I) OptiBond FL (adhesive alone), (II) OptiBond FL (primer and adhesive) (Kerr Corp., Brea, CA, USA), (III) Scotchbond Universal (3M, St. Paul, MN, USA) combined with OptiBond FL adhesive, (IV) Fissurit (VOCO GmbH, Cuxhaven, Germany), (V) Helioseal Clear (Ivoclar Vivadent AG, Schaan, Liechtenstein). A scanning electron microscope was used to assess marginal adaptation before and after simultaneous fatigue and thermocycling. The percentages of continuous margins (CMs) were quantified before and after the fatigue test and statistically compared (Shapiro-Wilk Normality test, two-way ANOVA with Fisher's post hoc test).

RESULTS

Helioseal Clear and Fissurit were fully transparent under near-infrared transillumination. The percentage of closed margins significantly decreased after loading in one group: OptiBond FL primer application before adhesive application significantly reduced marginal adaptation.

CONCLUSION

OptiBond FL (adhesive), Scotchbond Universal with OptiBond FL (adhesive), Fissurit, and Helioseal Clear provided excellent marginal adaptation. However, using OptiBond FL primer on enamel negatively impacted adaptation. Helioseal Clear and Fissurit, as transparent sealants, may allow lesion monitoring using an 850 nm transillumination camera.

摘要

背景

本研究旨在分析和比较五种用作窝沟封闭剂的树脂基材料在同时进行疲劳和热循环前后的透明度和边缘适应性。检验了两个无效假设：（1）所有测试材料都能使封闭的咬合面龋损透光。（2）同时进行疲劳和热循环前后边缘适应性没有差异。

方法

将40颗有早期咬合面龋损的拔除人类磨牙随机分为五组。在应用以下封闭剂之前和之后，采集清洁后的咬合面近红外透光图像：（I）OptiBond FL（仅粘合剂），（II）OptiBond FL（底漆和粘合剂）（美国加利福尼亚州布雷亚市科尔公司），（III）Scotchbond Universal（美国明尼苏达州圣保罗市3M公司）与OptiBond FL粘合剂联合使用，（IV）Fissurit（德国库克斯港VOCO有限公司），（V）Helioseal Clear（列支敦士登公国沙恩市义获嘉伟瓦登特股份公司）。使用扫描电子显微镜评估同时进行疲劳和热循环前后的边缘适应性。在疲劳试验前后对连续边缘（CMs）的百分比进行量化，并进行统计学比较（夏皮罗-威尔克正态性检验，带有费舍尔事后检验的双向方差分析）。

结果

在近红外透光下，Helioseal Clear和Fissurit完全透明。一组加载后封闭边缘的百分比显著降低：在应用粘合剂之前应用OptiBond FL底漆显著降低了边缘适应性。

结论

OptiBond FL（粘合剂）、Scotchbond Universal与OptiBond FL（粘合剂）、Fissurit和Helioseal Clear提供了优异的边缘适应性。然而，在牙釉质上使用OptiBond FL底漆会对适应性产生负面影响。Helioseal Clear和Fissurit作为透明封闭剂，可能允许使用850 nm透光相机监测龋损。
