Abstract
Most of “all-in-one” dental adhesives contain a mixture of hydrophilic and hydrophobic components that are dissolved in an organic solvent. This variability between the adhesives would affect their interaction with tooth structures. Flaw in this interaction, represented by poor dentin hybridization might affect the treatment success. Thus, the objective of the study was to compare between two different all-in-one self-etch adhesives, by examining the nanoleakage expression at dentin-resin interface.
Methodology: Tetric-N- bond self-etch adhesive (TN; Ivoclar/Vivadent) and Tri-S bond plus (TS; Kuraray Noritake) “all-in-one” self-etch adhesives were used for bonding resin composite to human dentin. After sectioning, they were subjected to ammoniacal silver nitrate solution followed by developing solution. Then, images were taken under scanning electron microscope (SEM) and energy-dispersive X-ray spectroscopy (EDS) to trace the silver grains at the dentin-resin interface.
Result: In TN group, SEM/EDS showed heavy silver deposition along the hybrid layer as well as throughout the adhesive layer, whilst in TS group the dentin-resin interface did not show silver deposition.
Conclusion: Water-based TN adhesive showed heavy silver deposition along the dentin-resin interface.
