Aim:
This was to evaluate the efficacy of pit and fissure sealant (FS) using two different application techniques for caries prevention assessed at five and ten years.
Methods:
The study was conducted using Delton(R) pit and fissures sealant applied with either rubber dam (RD) (Group A: 50 children, 200 first permanent molars, 120 second permanent molars) or cotton wool rolls (CR) (Group B: 50 children, 200 first permanent molars, 112 second permanent molars). At five and ten years FS were evaluated for retention, loss and incidence of occlusal and proximal carious lesions recorded.
Statistics:
The data were analysed with the Chi- square test comparing the results obtained for first permanent molars and second permanent molars at five and ten years.
Results:
There was no statistical difference between results in the two groups (p< or =0.05). The highest retention rate, 81.7%, was found for second permanent molars sealed under RD at the five year assessment. The lowest, 64.3% also for second molars sealed under CR humidity control at ten years.
Conclusions:
Pit and fissure sealants are a valid preventive approach that can be applied with similar results with rubber dam or cotton rolls.
