What this trial studies

This clinical trial investigates the impact of silver diamine fluoride (SDF) and a combination of SDF with potassium iodide (SDF+KI) on dental caries in healthy children aged 4-10. The study aims to evaluate the effectiveness of these treatments in arresting caries and their effects on the oral microbiome. Participants will receive one of the two treatments and return for follow-up assessments to analyze changes in saliva composition and microbial inhabitants. The research is conducted at King Abdulaziz University with informed consent from parents.

Why it matters

Potential benefit: If successful, this study could provide an effective non-invasive treatment option for managing dental caries in young children.

How similar studies have gone: Other studies have shown promising results with silver diamine fluoride in caries management, indicating potential success for this approach.
