Retention of sealants on healthy enamel vs early carious enamel in back teeth
Official title: Retention of Pits and Fissure Sealants on Non Carious vs Initial Carious Enamel Lesions in Posterior Teeth, a Non Randomized Clinical Study
Run by Foundation University Islamabad · NCT07330089 · Data updated 2026-11-12
This observational study tests whether pits and fissure sealants stay in place longer on back teeth with no caries versus early caries in people aged 7–18.

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.
