This randomized clinical trial evaluated the retention of composite resin restorations in carious primary molars among 150 children aged 4-9 years. The study compared the effects of silver diamine fluoride (SDF) with and without potassium iodide (KI) on restoration retention. At 12 months, retention rates were 76% for SDF + KI, 74% for SDF alone, and 72% for restorations without SDF, showing no significant differences (p = 0.53).
Key findings
- At 12 months, retention rates were 76% for SDF + KI, 74% for SDF alone, and 72% for CRR alone.
- Significant differences in colour match and marginal discoloration were observed between groups (p < 0.001).
- No significant difference in secondary caries was found (p = 0.78).
Why it matters
The findings suggest that incorporating SDF into caries management protocols for primary molars does not compromise the retention of composite restorations. Improved aesthetics with SSKI may enhance patient satisfaction.
