Super Dentin: Beyond the Biomimetic Interface

1 hour 12 minutes 1 hr CPD/CE

Professor Junji Tagami explores the science of dentin bonding and the concept of super dentin. Using SEM and OCT findings, he examines how self-etch and etch-and-rinse systems shape the hybrid layer, the role of MDP in durable bonds, and how to minimise post-operative sensitivity.

Included with All-Access membership, along with every other lecture in the library.

About this lecture

Super Dentin: Beyond the Biomimetic Interface

Join Professor Junji Tagami, an esteemed leader in adhesive dentistry whose pioneering research has reshaped modern restorative techniques, for an in-depth lecture on the complexities of dentin bonding and the concept of “super dentin.” This webinar offers a comprehensive exploration of bonding mechanisms, the formation of reinforced hybrid layers, and their implications for long-term adhesive success. Professor Tagami delves into the performance characteristics of self-etching and etch-and-rinse systems, explaining how they influence the strength and quality of the hybrid layer and overall bond integrity. Using detailed SEM imagery and findings from Optical Coherence Tomography (OCT) studies, he demonstrates the impact of polymerisation shrinkage stress and shares techniques to minimise post-operative sensitivity and achieve superior marginal adaptation.You will also gain insights into the latest advancements in adhesive materials, including ion-releasing systems and the unique role of MDP in forming highly durable bonds. The lecture concludes with a look into future trends, such as pico restorations and innovative material technologies that promise to create even more reliable, stable interfaces between restorations and tooth structures.

What you'll learn

Learning Aims & Objectives

To provide a detailed overview of the mechanisms behind self-etch and etch-and-rinse adhesive systems and their impact on the hybrid layer.
To explain the formation of “super dentin” and its enhanced mechanical properties, including increased microhardness and chemical stability.
To discuss the role of polymerisation shrinkage stress in bonding and techniques for mitigating gap formation and post-operative sensitivity.
To present findings from advanced diagnostic methods, such as OCT, and their application in understanding bonding performance.
To highlight the significance of flowable composite resins in achieving durable, gap-free restorations.
To explore future trends in adhesive dentistry and the potential of cutting-edge technologies to further enhance restoration stability.
