This study aimed to evaluate the microleakage and penetration of two hydrophilic sealants, Embrace Wetbond¢â and Ultraseal XT¢ç hydro¢â, when applied on dry and moist enamel, as compared to a conventionally used hydrophobic sealant, Clinpro¢â.

A total of 60 sound human third molars were randomly divided into 5 groups according to the enamel moisture control and the sealant material used. After sealant application, the teeth were thermocycled and immersed in 1% methylene blue dye. Subsequently, the teeth were sectioned twice and the sections were examined using an optical microscope and image analysis software.

Application of Embrace Wetbond¢â on either dry or moist enamel resulted in more microleakage than Clinpro¢â. Application of Ultraseal XT¢ç hydro¢â on dry enamel showed a similar level of microleakage to Clinpro¢â, but application on moist enamel resulted in more microleakage. There were no significant differences between the groups in penetration.

In conclusion, application of hydrophilic sealants on moist enamel did not improve the sealing ability and showed lower sealing ability than that of Clinpro¢â applied on dry enamel.
