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 the hybrid materials Vitremer and Dyract when used as pit and fissure sealants.


METHODS
The materials were applied in pairs on the mandibular permanent first molars of 100 children, 7 to 8 years old.


RESULTS
After 12 months of sealing, the clinical evaluation presented rates of 95.9% and 85.7% of complete retention for Dyract and Vitremer, respectively, indicating 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.


CONCLUSIONS
The hybrid materials were able to control occlusal caries.
