Carbamide peroxide effective for partially improving silver diamine fluoride staining Lesions: Study
Researchers have found in a new study that while potassium iodide (KI) did not reduce silver diamine fluoride (SDF) staining, microabrasion showed limited aesthetic benefit. In contrast, 15% carbamide peroxide (CP) proved more effective in partially improving the color of SDF-stained lesions.
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). 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.
