Assessment of Embrace-WetBond and Fissurit F Pit and Fissure Sealants’ Marginal Sealing Abilities

OBJECTIVES: The goal of the current research was to assess marginal sealing abilities of 2 commercial pit and fissure sealants. MATERIALS AND METHODS: A total of 30 premolar teeth were equally classified into 2 groups: Group A-application of Embrace-WetBond sealant and Group B-application of Fissurit F, Voco sealant. After sealant placement, samples were preserved in artificial saliva for 48 hours prior to thermocycling. Later, samples were submerged for 24 hours in a 2% methylene blue solution. The amount of microleakage based on the quantity of dye penetration at interface between the tooth substance and sealant was compared under an optical stereomicroscope. The obtained data were statistically analysed for the dye penetration scores in both groups. RESULT: It was observed that 8 samples from Group A (53%) had no dye penetration (Grade 0), whereas 4 samples from Group B (26%) showed Grade 0 penetration. In 5 out of 15 samples (33%) from Group B, the dye penetration was the greatest (Grade 3; P = 0.012). CONCLUSION: It was concluded that Embrace-WetBond had lesser microleakage compared to group 2-Fissurit F, Voco sealant.
