Abstract

Purpose: This study aimed to investigate the effect of potassium iodide (KI), bleaching, and microabrasion on the colour of caries-like lesions treated with silver diamine fluoride (SDF).

Materials and methods: Enamel specimens were demineralised and then randomised into six groups (n = 15): G1, demineralised; G2, remineralised with 38% SDF to create stained remineralised caries-like lesions (s-RCLs); G3, s-RCLs + KI; G4, s-RCLs + KI + at-home bleaching protocol (15% carbamide peroxide (CP), 4 h/d×7); G5, s-RCLs + KI + microabrasion (6.6% hydrochloric acid); G6, s-RCLs + KI + microabrasion and at-home bleaching protocol. Colour was measured spectrophotometrically at baseline, after demineralisation, and after the treatments. Outcomes were analysed using ANOVA followed by Tukey's test (α = 0.05).

Results: The increased colour change after demineralisation (ΔE ≥ 6.7) indicated the creation of white spot lesions. G2 (ΔE = 12.3) and G3 (ΔE = 11.1) were significantly discoloured (P ≤ 0.0039), with no significant difference between them, and significantly darker (P 0.0001) than G1 (ΔE = 0.4) and G5 (ΔE = 4.4). G2 was significantly (P ≤ 0.0325) darker than G1, G4, G5, and G6 (ΔE = 0.4, 8.1, 4.4, 7.9), respectively.

Conclusion: While KI did not reduce SDF staining, microabrasion offered limited aesthetic improvement. However, 15% CP demonstrated greater efficacy in partially improving the colour outcome of SDF-stained lesions.

碘化钾、漂白和微磨对二胺氟化银染色再矿化龋病变颜色的影响。

目的：本研究旨在探讨碘化钾（KI）、漂白和微磨对氟化二胺银（SDF）治疗的龋样病变颜色的影响。材料和方法：将牙釉质标本脱矿后随机分为6组（n = 15）： G1组，脱矿组；G2, 38% SDF再矿化，形成染色的再矿化龋齿样病变（s-RCLs）；G3, s-RCLs + KI；G4， s-RCLs + KI +家庭漂白方案（15%过氧化脲（CP）， 4小时/d×7）；G5， s-RCLs + KI +微磨（6.6%盐酸）；G6， s-RCLs + KI +微磨和家用漂白方案。在基线、脱矿后和处理后分光光度法测量颜色。结果分析采用方差分析和Tukey检验（α = 0.05）。结果：脱矿后颜色变化增大（ΔE≥6.7）提示出现白斑病变。G2 （ΔE = 12.3）和G3 （ΔE = 11.1）颜色明显变浅（P≤0.0039），两组间差异无统计学意义，且颜色明显深于G1 （ΔE = 0.4）和G5 （ΔE = 4.4）（P 0.0001）。G2比G1、G4、G5、G6的颜色更深（P≤0.0325）（ΔE = 0.4、8.1、4.4、7.9）。结论：虽然KI不能降低SDF染色，但微磨蚀对美观的改善有限。然而，15% CP在部分改善sdf染色病变的颜色结果方面表现出更大的疗效。
