摘要

目的:本研究探讨了树脂改性玻璃离子水泥(RMGIC)在使用几种龋洞消毒剂(光致发光激活的 ICG、Pr 和 SDF)后对受龋齿影响的牙本质的 SBS 影响。方法:选择 40 颗基于 ICDAS 标准 3 和 4 的 CAD 牙齿。牙齿被随机分为四组(n = 10)。1-4 组的样本分别用洗必泰(CHX)、吲哚菁绿(ICG)、蜂胶(Pr)和 38% 的二胺氟化银(SDF)进行消毒。消毒后的样品与 RMGIC 结合并老化。使用万能试验机对 SBS 进行评估。使用体视显微镜评估粘接失败情况。多组比较采用 Tukey's 诚实差异(HSD)检验。方差分析使用平均值和标准差对各组进行比较。结果CHX 消毒和 RMGIC 粘合的 CAD 粘合值最高。第 4 组 SDF 消毒和 RMGIC 粘合试样的粘接值最低。与其他处理方法相比,用 CHX 消毒并用 RMGIC 粘接的第 1 组试样的粘接完整性最高(p < 0.05)。结论:在用树脂改性玻璃离子粘结剂粘结之前,洗必泰是对受龋齿影响的牙本质进行消毒的最佳消毒剂。

Artificial Ageing and Disinfection of Caries Affected Dentin on the Bond Integrity and Failure Analysis of Ion-Releasing Restorative Material
Aim: This study examines the SBS of resin-modified glass ionomer cement (RMGIC) on caries-affected dentin after using several cavity disinfectants (ICG activated by PDT, Pr, and SDF). Method: 40 CAD based on ICDAS criteria 3 and 4 teeth were chosen. Teeth were randomly divided into four groups (n = 10). Samples in Groups 1–4 were disinfected with chlorhexidine (CHX), indocyanine green (ICG), Propolis (Pr), and 38% silver diamine fluoride (SDF), respectively. Disinfected samples were bound to RMGIC and aged. SBS was evaluated using the universal testing machine. Stereomicroscope was used to assess bond failure. To compare many groups the Tukey’s Honestly Significant Difference (HSD) test was used. ANOVA was used to compare groups using mean values and standard deviations. Results: CHX-disinfected and RMGIC-bonded CAD had the highest bond values. Group 4 SDF-disinfected and RMGIC-bonded specimens had the lowest bond values. Group 1 samples disinfected with CHX and bonded with RMGIC had the highest bond integrity (p < 0.05) compared to other treatments. Conclusion: Chlorhexidine is the best disinfectant for caries-affected dentin before bonding with resin-modified glass ionomer cement.
