Abstract

Evaluation of composite resin microleakage with using different bonding agents by micro computed tomography Conclusion: Newer adhesive systems have better success achievements and recommended to be used in practical bases.

Evaluation of Microvoid and Microleakage Potential of Bulk-Fill Resin Composites in MOD Restorations

“…HEMA also forms hydrogen bonds within the microporosities of demineralized dentin, undergoes hygroscopic expansion after polymerization, mechanically clamps to the substrate, and bonds to the dentin surface with stronger bonds [37]. According to this study, the presence of HEMA resulted in less microleakage in the seventh-generation (Palfique bond) and eighth-generation (Palfique universal bond) adhesive system compared to the sixth-generation (One-up Bond F Plus) adhesive system [39]. In our study, the total-etch (OptiBond FL, Kerr) adhesive system showed lower microleakage than the self-etch (Gluma, Kulzer) adhesive system in all groups.…”

“…As a result of the study, the highest microleakage was observed in the One-up Bond F Plus group, followed by Palfique bond [38]. They stated that the reason why One-up Bond F Plus showed the highest leakage was that it does not contain HEMA (hydroxyethyl methacrylate) [39]. Since the hydrophilicity of HEMA makes it an excellent adhesion-promoting monomer and increases the wetting of dentin, it significantly increases the bond strength and reduces microleakage.…”
