Study of plasma treatment effects on dental bond improvement, biofilm destruction, and oxidation prevention of AgNWs

Abstract

[EMBARGOED UNTIL 8/1/2024] Non-thermal plasma techniques have gained significant attention and applications in various fields, including the medical, dental, and industrial sectors. These techniques offer unique advantages in areas such as cell proliferation, cancer treatment, bacterial sterilization, biomaterial surface treatments, bond strength improvement, tooth whitening, oral bacterial deactivation, material surface modifications, package sterilization, and plant germination. This study specifically focuses on the application of non-thermal plasma techniques in tooth restoration materials for bonding performance improvement, oral biofilms destruction and recovery inhibition, and the oxidation protection of silver nanowires (AgNWs). The effects of plasma treatment on the bonding performance of lithium disilicate-resin and zirconia-resin, as well as brackets-teeth enamel bonding, were investigated in terms of immediate and long-term performance after completing the bonding procedures. The study also examined the impact of plasma treatment on the survival rate and recovery performance of dual-species oral biofilms under oxidative stress conditions. Furthermore, the report investigated the conductivity stability of AgNWs and the effectiveness of trimethylsilane (TMS) plasma nanocoatings. Additionally, the study also analyzed underlying mechanisms of the plasma treatment, which are crucial for optimizing its application in various dental and industrial processes. Overall, this study provides insights into the potential application of non-thermal plasma techniques for enhancing dental restoration material bond strength, inhibiting oral biofilm recovery, and protecting AgNWs from oxidation.
