This randomized 18-month split-mouth clinical study compared BioCoat™, a bioactive resin-based pit and fissure sealant, with the fluoride-containing resin sealant Fissurit FX in children aged 7–9 years. Each material was applied to a contralateral mandibular permanent first molar. At 18 months, success rates were 90.2% for BioCoat™ and 88.2% for Fissurit FX, with no statistically significant difference (p > 0.05). The materials also had similar retention, marginal outcomes, and secondary caries findings; patient-related factors were not significantly associated with success.
Key findings
- At 18 months, success was 90.2% with BioCoat™ and 88.2% with Fissurit FX (p > 0.05).
- Median survival times were 17.72 months for BioCoat™ and 17.49 months for Fissurit FX (p = 0.744).
- Retention, marginal discoloration-adaptation, and secondary caries outcomes did not differ significantly between materials (p > 0.05).
- No significant association between patient-related factors and material success was identified (p > 0.05).
Why it matters
Sealant performance over time is relevant to preventing occlusal caries in children. In this study, the bioactive resin sealant performed similarly to a conventional fluoride-containing resin sealant across the reported clinical outcomes, providing comparative evidence for these materials in pediatric patients.
What to keep in mind
Follow-up was limited to 18 months, and the study included children aged 7–9 years receiving sealants on mandibular permanent first molars.
