Abstract
Background: Pit and fissure sealants are considered a major tool of prevention. A new hydrophilic sealant which can be used in young permanent will be better for caries prevention. Objectives: The aim of this study is to assess the retention of the hydrophilic resin-based fissure sealant compared to the hydrophobic conventional fissure sealants. Material and Method: 22 premolars were collected and randomly allocated into two groups (n= 11), Group I (test); hydrophilic sealant Embrace wetbond; Group II (control) hydrophobic sealant Helioseal F. The buccal surface of all teeth was prepared, flattened, etched and rinsed. Group I was contaminated with artificial saliva then dried with cotton pellet and Group II was dried with air only. Sealants were applied and cured. Specimens were thermocycled and shear bond strength was evaluated using a universal testing machine. A stereomicroscope at magnification ×25 was used to evaluate mode of failure of each specimen. Results: According to statistical analysis (Mann whitney U), Hydrophilic sealant demonstrated significant lower median shear bond strength values at P Conclusion: Hydrophilic sealant retention is not efficient as conventional hydrophobic sealant.
