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.
The study was conducted using Delton 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.
There was no statistical difference between results in the two groups (p0.05). 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.
