Abstract:
Objectives: To compare the effectiveness of 3 types of pit and fissure sealants namely, glass ionomer sealants (GC FUJI VII), high viscosity GIC used as ART sealant (GC Fuji IX EXTRA), and hydrophilic resin sealant (Embrace Wet Bond) when placed under salivary contamination in terms of marginal leakage and depth of penetration.
Methodology: Sixty extracted non-carious maxillary premolars were randomly divided into three groups of 20 each. Samples were prepared and sealant was applied as per the manufacturer’s instructions. Prior to sealant application the tooth surfaces were wetted with artificial saliva for 5 seconds using a micro brush applicator and air-thinned for 1 second. The samples underwent thermocycling followed by immersion in 5% methylene blue for 24 hours. The samples were sectioned buccolingually and analysed under a stereomicroscope to assess microleakage and depth of penetration. Mann-Whitney U test was applied to test the statistical significance of the difference in the mean values of microleakage and percentage penetration, with a p-value of <0.05 considered to be statistically significant.
Result: The hydrophilic resin sealant showed the least microleakage and greatest depth of penetration, with the differences in both parameters being statistically significant.
Conclusion: The hydrophilic resin sealant can be considered a promising material for sealing fissures, especially in very young children where isolation is difficult.
