Background and Aim: Silver diamine fluoride (SDF) is effective for arresting dental caries. However, its application results in dark tooth discoloration, raising concerns among pediatric patients and their parents. This study assessed the effects of potassium iodide (KI) plus hydrogen peroxide (H2O2), H2O2, and Tooth Stain Remover (TSR) on SDF-induced discoloration of artificially demineralized permanent enamel.
Materials and Methods: In this in vitro study, the buccal surface enamel of 33 sound premolars was artificially demineralized and exposed to 38% SDF. The specimens were then randomly assigned to 3 groups of (I) KI + H2O2 (application of water-soluble KI followed by 35% H2O2 on the discolored surface for 3 minutes), (II) H2O2 (application of 35% H2O2 for three 20-minute cycles), and (III) TSR (application of TSR for 3 minutes on the discolored surface). The color parameters were measured at baseline, 1 week after the application of SDF, and 1 week after the application of the abovementioned bleaching agents by a spectrophotometer. Data were analyzed by ANOVA and Tukey test (alpha=0.05).
Results: SDF caused significant color change (ΔE) of demineralized enamel in all groups (ΔE=36-40), with no significant difference among the study groups (P=0.361). Application of all bleaching agents significantly resolved the dark discoloration in all groups, but KI + H2O2 was significantly more effective than H2O2 and TSR (P<0.001). TSR was the least effective (P<0.001).
Conclusion: Within the study limitations, the results showed optimal efficacy of KI + H2O2 for correction of 38% SDF-induced discoloration in artificially demineralized permanent enamel.
