Caries arrestment at the individual (patient) level · Children and adults with active dental caries (aged 1-50; mostly preschool/school children with primary dentition)
Compared with other caries-management methods, SDF may increase caries arrestment at the individual level, but the pooled estimate is very imprecise (low certainty).
