Is this trial a fit for you?

Likely a good fit

Children aged 14 years or younger with caries in primary teeth who need SDF treatment as per local guidelines and have informed consent from a parent/guardian.

Probably not a fit

Patients with advanced lesions near the pulp, allergies to silver/ammonia/iodine, or those who object to tooth staining may not benefit.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a prospective single-cohort observation conducted in a public primary care dental clinic. Children with caries in their baby teeth who need SDF treatment will receive it according to local guidelines and be followed for 12 months with check-ups at 1, 6, and 12 months. Outcomes include whether caries progress stops, the frequency of side effects like staining or discomfort, and parent satisfaction. Assessments combine clinical exam findings, patient-reported information, and, when needed, radiographs. The study aims to provide real-world evidence on effectiveness and safety of current SDF formulations in routine practice.

Why it matters

Potential benefit: If successful, the approach could support wider use of SDF in routine care to arrest caries in primary teeth with minimal invasiveness.

How similar studies have gone: Previous controlled trials have shown high arrest rates with SDF, but evidence in routine clinical practice remains limited and this study adds real-world data.
