Arrest or reversal of noncavitated and cavitated root carious lesions · Adults (including institutionalized/older adults) with noncavitated and cavitated carious lesions on root surfaces (permanent teeth)
1% chlorhexidine + 1% thymol varnish may not differ from 38% SDF solution (applied annually) for arrest or reversal of root carious lesions (RR 0.88, 95% CI 0.14 to 5.6; very low certainty).
