Influence of Corbin and graphene oxide nanoparticles on the adhesive properties of dentin bonding polymer - SEM study

Abstract

Abstract:

Background:

Dental adhesive systems play a crucial role in the success of restorative dentistry by facilitating durable bonds between restorative materials and tooth structures. This study investigates the influence of Corbin and graphene oxide nanoparticles on the adhesive properties of dentin bonding polymers, focusing on morphological changes at the dentin-adhesive interface.

Methods:

Human dentin specimens were prepared, and dentin bonding polymers were formulated with Corbin and graphene oxide nanoparticles. The experimental groups included a control group (adhesive system only), Corbin group, Graphene Oxide group, and Corbin + Graphene Oxide group. After adhesive application, specimens were subjected to SEM analysis to assess morphological features, including resin tag length and width, and overall interface integrity.

Results:

The Corbin and Corbin + Graphene Oxide groups exhibited significantly longer resin tags compared to the control group, indicating improved resin penetration into dentin tubules. The combination of Corbin and graphene oxide showed a synergistic effect, leading to longer resin tags and wider adhesive interfaces. The overall interface integrity score was significantly higher in the Corbin + Graphene Oxide group compared to the control.

Conclusion:

Incorporating Corbin and graphene oxide nanoparticles into dentin bonding polymers positively influenced the morphological characteristics of the dentin-adhesive interface. This enhancement suggests the potential for improved adhesive properties, with implications for the longevity and durability of adhesive restorations in restorative dentistry.
