摘要

目的:本研究的目的是评估表面密封剂对修复材料暴露于铁糖浆中的抗污性的影响。方法:采用复合材料(Dyract XP)、微复合材料(Filtek Z250)和纳米复合材料(G-aenial Anterior)三种修复材料各制备60个标本。标本分为三组(n = 20),分别浸泡于两种铁糖浆(Ferrum和Ferro Sanol B)和蒸馏水中。每组设密封(BisCover(+))和未密封(BisCover(-))两个亚组(n = 10)。使用CIEDE2000 (ΔE00)指标计算4、8、24、48和72小时基线和测量值之间的颜色变化。数据采用四因素混合设计方差分析。结果:本研究的第一个零假设,即使用表面密封剂不会减轻修复材料对染色的敏感性,被驳回。所有修复材料在Ferro Sanol B中测试的ΔE00值在BisCover(+)组和BisCover(-)组之间存在显著差异(Ferro Sanol B/BisCover(+)组的p 00值显著低于Ferrum/BisCover(+)组(p = 0.002),第二个零假设即不同形式的铁糖不会影响修复材料的耐染色性被驳回。每种修复材料的ΔE00值都不同,第三个零假设即修复材料的类型不会影响抗染色性,被拒绝。结论:表面密封胶的应用显著提高了修复材料的颜色稳定性。铁糖浆的含量也是影响颜色变化的重要因素。纳米杂化复合材料似乎更能抵抗铁糖浆的染色作用。

Can the use of surface sealant on restorative materials prevent discoloration related to iron syrup supplements?

Purpose: The purpose of this study was to evaluate the impact of surface sealants on the stain resistance of restorative materials exposed to iron syrups.

Methods: Sixty specimens were prepared from each of three restorative materials-compomer (Dyract XP), a microhybrid composite (Filtek Z250), and a nanohybrid composite (G-aenial Anterior). Specimens were divided into three solution groups (n = 20) and immersed in two iron syrups (Ferrum and Ferro Sanol B) and distilled water. Two subgroups, sealed (BisCover ( +)) and unsealed (BisCover (-)), were established for each group (n = 10). Color changes between baseline and measurements at 4, 8, 24, 48, and 72 h were calculated with CIEDE2000 (ΔE00) metrics. Data were analyzed with 4-factor mixed-design ANOVA.

Results: The first null hypothesis of this study that the use of surface sealant would not mitigate the restorative materials' susceptibility to staining was rejected: significant differences were found between BisCover ( +) and BisCover (-) groups in ΔE00 values for all restorative materials tested in Ferro Sanol B (p < 0.001) and Ferrum (p = 0.002) solutions. The ΔE00 values in the Ferro Sanol B/BisCover ( +) groups were significantly lower than in Ferrum/BisCover ( +) groups (p = 0.002), the second null hypothesis that different forms of iron syrups would not impact the staining resistance of restorative materials was rejected. ΔE00 values were different for each restorative materials tested, the third null hypothesis that the type of restorative material would not affect staining resistance was rejected.

Conclusions: The application of surface sealant significantly improved the color stability of restorative materials. The content of iron syrups was also an important factor affecting color change. Nanohybrid composites seem to be more resistant to the staining effects of iron syrups.
