Abstract

Purpose: This study was conducted to evaluate the impact of silver diamine fluoride (SDF) on Glass ionomer restoration (Fuji IX) microleakage and shear bond strength. Material and Methods: The present study was carried out on 40 primary extracted human molars. The primary molars were equally divided into 2 groups (Group I, Group II). (Group I) including: 20 primary molars were used for microleakage testing under stereomicroscope at x40. (Group II) including: 20 primary molars were used for shear bond strength testing using Instron Universal Testing Machine.  Each group was subdivided into 2 subgroups; subgroup 1 which been treated with SDF then restored by Glass ionomer restoration and subgroup 2 which was restored with Glass ionomer without SDF. Result: In microleakage analysis comparing both groups in both surfaces, the highest mean value was recorded in glass ionomer without SDF group in the occlusal surface (758.77±69.65), followed by glass ionomer without SDF group in the gingival surface (643.74±83.77), then glass ionomer with SDF group in the occlusal surface (126.06±10.70), with the least value was recorded in Glass ionomer with SDF group in the gingival surface (109.12±5.58). In shear bond strength analysis, the higher mean value was recorded in Glass ionomer with SDF group (9.38±1.12), while that recorded in Glass ionomer without SDF group was (1.97±0.16). Conclusion: The results of the current analysis suggest that the use of SDF minimized microleakage and increased intensity of shear bond strength for Glass ionomer restoration.
