Characteristics of the included studies
| Study/Country | Duration of follow-up (months) | Age of participants (years) and caries experience at baseline | Intervention | Comparison |
|---|---|---|---|---|
| Bijella, Brazil | 24 | 3 – 4 dfs=3.42-4.59 | 12% SDF applications for 2 min, onto all tooth surfaces; 3 groups (every 3, 6 and 12 months) | No treatment |
| Dos Santos, Brazil | 12 | 5 – 6 dft=4.56-4.71 | 30% SDF applications for 3 min, onto all carious tooth surfaces (once) | GIC used as interim therapeutic restoration repeated at the 6-month evaluation if lost |
| Llodra, Cuba | 36 | 6 or more (mean 6.29, SD 0.48) dmfs=3.35-3.68 | 38% SDF applications for 3 min, onto all carious primary tooth surfaces (every 6 months) | No treatment |
| Chu, China | 30 | 3 - 5 (mean 4, SD 0.8) dmfsant=4.73 | 38% SDF applications (time not reported), onto active carious upper anterior tooth surfaces (every 12 months) | FV (every 3 months) and water (interval not reported), applications onto active carious upper anterior tooth surfaces |
SD= standard deviation, SDF= silver diamine fluoride, FV= 5% sodium fluoride varnish, GIC= high-viscosity glass-ionomer cement, dfs= mean number of decayed and filled tooth surfaces in primary teeth, dft= mean number of decayed and filled primary teeth, dmfs= mean number of decayed, missing and filled tooth surfaces in primary teeth, dmfsant=mean number of decayed, missing and filled tooth surfaces in anterior primary teeth
