Abstract
Objectives: This study assessed the antibacterial effect and the shear bond strength of self-etch adhesive after incorporating Graphene oxide nanoparticles.
Materials and methods: Graphene oxide nanoparticles was synthetized and incorporated within a self-etch adhesive (Quadrant Uni-SE-Bond) with 0% control group (without Graphene) (group I), 2% (group II) and 5% (group III). The antibacterial effect was evaluated against S. Mutans using agar well diffusion method. 24 holes (n=8) with a diameter of 6-8 mm were performed and the inhibition zone was evaluated in millimeters after 24 hrs. For shear bond strength, 12 premolars were sectioned horizontally to expose dentin and to obtain 24 specimens for assessing the bond strength (n=8). Composite cylinders (2x2 mm) were bonded to the dentin and subjected to shear bond strength using universal testing machine.
Results: The incorporation of Graphene oxide nanoparticles into self-etch adhesive showed a significantly dose-dependent antibacterial effect. On the other hand, the shear bond strength reported no significant difference between the three groups.
Conclusion: Addition of Graphene oxide NP to self-etch adhesive produced an antibacterial effect without affecting the bond strength.
