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 ( P < 0.05).
Results:
The intragroup comparison showed a significant color change after SDF application among all three groups and after GIC restoration in Group 2 (ΔE = 16.57 ± 12.27) and Group 3 (ΔE = 22.32 ± 11.06) ( P < 0.05). On intergroup comparison, Group 2 showed higher ΔE values than Group 3 which was statistically nonsignificant ( 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.
