Is this trial a fit for you?

Likely a good fit

Children and adolescents aged 7–18 with fully erupted first or second permanent molars and no contraindications to sealants.

Probably not a fit

Patients with poor oral hygiene, high caries risk, or conditions affecting sealing durability may not benefit.

What this trial studies

This study compares the 3-, 6-, and 12-month retention of Conseal F sealant on first and second permanent molars in two groups: non-carious enamel (ICDAS 0) and early carious enamel (ICDAS I-II). It uses an observational, quasi-experimental design in which participants are assigned to groups based on ICDAS scores and sealed after standard etching, with follow-up visits to assess retention by Simonson criteria. Data will be analyzed with chi-square tests to determine if retention differs between the groups at each time point. The study aims to inform follow-up strategies for optimal caries prevention in permanent molars.

Why it matters

Potential benefit: If successful, the findings could help clinicians tailor follow-up intervals and prevention plans based on initial enamel status.

How similar studies have gone: Previous research has explored sealant retention, but this study addresses a specific comparison between non-carious and early carious enamel in a defined pediatric population.
