Key Points

To compare tooth discoloration effects from silver diamine fluoride treated primary molars after restorations.
Randomized trial involving 45 carious primary molars in children.
Samples divided into three groups: SDF only, SDF plus immediate GIC, and SDF plus delayed GIC.
Color measurement before and after SDF application and GIC restoration using spectrophotometer.
Significant color change observed after SDF application across all groups.
Group 2 (immediate GIC) showed ΔE = 16.57 ± 12.27 after restoration; Group 3 (delayed GIC) showed ΔE = 22.32 ± 11.06.
No significant difference in ΔE between Group 2 and Group 3.

Abstract

AIM: To compare tooth discoloration in silver diamine fluoride (SDF) treated primary molars before and after delayed restoration with glass ionomer cement (GIC). MATERIALS AND METHODS: A total of 45 carious primary molars in children were recruited, having an International Caries Detection and Assessment Score of 5. The samples were divided into three groups of 15 each: Group 1 - SDF application, Group 2 - SDF application followed by immediate GIC restoration, Group 3 - SDF application followed by delayed GIC restoration (2 weeks). Color measurement using a spectrophotometer was done before SDF application, after SDF application, and after GIC restoration in their respective groups. Change in color (ΔE) was measured using the ΔE2000 formula. The data was used for statistical analysis and level of statistical significance was set at P 0.05). CONCLUSION: SDF is a widely used anticaries agent. Both immediate and delayed GIC restorations effectively masked SDF-induced discoloration in primary molars.
