Comparison of the Effect of Different Bonding Agents on the Microleakage of Two Hydrophilic Pit and Fissure Sealants: An Study.

AIM

To compare the impact of fifth- and seventh-generation bonding agents on the microleakage between Embrace WetBond sealants and Ionoseal.

MATERIALS AND METHODS

Forty extracted human premolar teeth were used for the study and grouped according to different sealants and bonding agents-group I: Embrace WetBond sealant with fifth-generation bonding agent; group II: Embrace WetBond sealant with seventh-generation bonding agent; group III: Ionoseal with fifth-generation bonding agent; group IV: Ionoseal with seventh-generation bonding agent. For microleakage evaluation, all the teeth were subjected to invasive sealant placement using the respective sealant materials in combination with bonding agents as specified. The treated teeth were stored at 37°C for 24 hours and then thermocycled for 100 cycles at temperatures of 5°C and 55°C with a dwell time of 30 seconds. In order to assess microleakage, the samples were immersed in 0.2% methylene blue dye for 24 hours, then sectioned in buccolingual direction, and evaluated under stereomicroscope.

RESULTS

The mean microleakage scores in group III were highest at 0.90 ± 0.57, while the least was in group IV at 0.30 ± 0.68, indicating that Ionoseal with seventh-generation bonding agent was the most effective. However, when the mean microleakage scores of the four groups were compared using Kruskal-Wallis test, it indicated that the differences were not statistically significant.
