A comparison of microleakage in self-etch fissure sealants and conventional fissure sealants with total-etch or self-etch adhesive systems.

Objective: The present study was conducted to compare microleakage in self-etching fissure sealants and conventional fissure sealants with total-etch or self-etch adhesive systems.

Settings And Design: This experimental study was conducted on 60 healthy third molars extracted from humans. The first group received Acid etch + Clinpro sealant, the second group received Acid etch + Single bond 2 + Clinpro sealant, the third group received Single bond universal (self-etching bonding) + Clinpro sealant, and the fourth group received prevent seal self-etching sealant.

Materials And Methods: An incision was made on the teeth after they were immersed in methylene blue 5%. The samples were then examined under a stereomicroscope and the dye penetration rate was measured based on the Williams and Winter criteria.

Statistical Analysis Used: The Kruskal-Wallis and Mann-Whitney tests were used for data analysis in SPSS-18 ( < 0.05).

Results: Group 1 which was treated with the conventional technique (acid + fissure sealant) had the highest rate of microleakage compared to Groups 2 and 3 ( < 0.001).

Conclusion: The results showed that the use of bonding results in a significant reduction in the microleakage of fissure sealants. The microleakage caused when using self-etch fissure sealant was not different from that caused by the use of the conventional method.
