Zhao et al., [24] (2019) | 19 | 2.6 ± 1.1 | 2.3 ± 0.9 | 3.0 ± 1.4 | Light microscope (20x) Adhesive | • Application of SDF followed by air-drying had no significant influence on the SBS of demineralized dentine to GIC • Application of SDF/KI followed by rinsing with water had no significant influence on the SBS of demineralized dentine to GIC | ns |
Gupta et al., [25] (2019) | 8 | 10.5 ± 10.5 (water) 8.9 ± 4.6 (polyacrylic acid) 9.7 ± 5.3 (chlorhexidine) |  | 22.3 ± 4.4* | Not reported | • Compared to polyacrylic acid, chlorhexidine and water, application of SDF/KI followed by rinsing with water increased the SBS of sound dentine to RMGIC | increase |
Puwanawiroj et al., [26] (2018) | 40 | 6.3 ± 4.6 | 7.4 ± 5.1 |  | Light microscope (40x) Mixed | • Application of SDF followed by rinsing with water and polishing had no significant influence on the mTBS of carious dentine to GIC | ns |
Wang et al., [29] (2016) | 20 | 24 h S-dentine Water 4.00 ± 1.68 D-dentine Water 3.84 ± 1.47 7 days S-dentine Water 5.83 ± 2.04 D-dentine 6.04 ± 2.24 | 4.25 ± 1.80 4.80 ± 2.53 (light) 4.74 ± 1.41 6.25 ± 2.60* (light) 5.19 ± 1.77 4.53 ± 2.34 (light) 6.21 ± 3.28 6.69 ± 2.72 (light) |  | Light microscope (40x) Cohesive | • Compared to no treatment and SDF treatment only, combination of SDF application and light illumination increased the mTBS of demineralized dentine to GIC 24 h after bonding, but this effect was not found after 7 days • Application of SDF with/without light illumination had no significant influence on the mTBS of sound dentine to GIC | increase/ns |
Koizumi et al., [32] (2016) | 10 | 18.4 ± 5.6 |  | 14.5 ± 5.2* | SEM Adhesive | • Application of SDF/KI reduced the mTBS of sound dentine to RMGIC | decrease |
Knight et al., [34] (2006) | 10 | 2.40 ± 0.88 |  | 2.83 ± 1.39 (rinse) 1.53 ± 0.74* (air-dry) | Not reported | • Application of SDF/KI and leaving the precipitate on the dentine surface reduced the SBS of sound dentine to GIC • Application of SDF/KI followed by rinsing with water to remove precipitate on the surface had no significant influence on the SBS of sound dentine to GIC | decrease/ns |
