Clinical evaluation of glass-ionomer/resin-based hybrid materials used as pit and fissure sealants

Objective: The objective of the present study was to clinically evaluate th e hybrid materials Vitremer and Dyract when used as pit and fissure sealant s. Method and materials: The materials were applied in pairs on the mandibu lar permanent first molars of 100 children. 7 to 8 years old. Results: Afte r 12 months of sealing, the clinical evaluation presented rates of 95.9% an d 85.7% of complete retention for Dyract and Vitremer, respectively, indica ting a statistically significant difference. The hybrid materials presented a statistically significant protective effect against caries compared with the control group at 6 and 12 months. Conclusion: The hybrid materials wer e able to control occlusal caries.
