History and Importance of Immediate Dentin Sealing
Immediate dentin sealing has become a crucial aspect of biomimetic restorative dentistry, with its origins tracing back to Tokyo Medical and Dental University. The concept was advanced by Dr. Pascal Manier, linking adhesive dentistry to biomimetic dentistry. Understanding carries detection, selective removal, cracks, and gaps are vital for successful restorations.
Evolution of Bonding Agents and Hybrid Layers
The evolution of bonding agents from early unpredictable systems to the introduction of new chemistries at Tokyo Medical and Dental University revolutionized dentin bonding. Molecules like phenyl-P and 10MDP changed the game by enhancing interactions with dentin and overcoming issues like shrinkage. Van Merebeek's research on the hybrid layer and different bonding systems further validated the significance of stable adhesive interfaces in dentistry.
Significance of Immediate Dentin Sealing Technique
The immediate dentin sealing technique revolutionized restorative procedures by utilizing self-etch systems like Linerbond 2 to simplify the bonding process. Studies revealed a substantial increase in bond strength with immediate dentin sealing compared to delayed approaches. Neutralizing the hierarchy of bondability and enhancing polymerization dynamics through immediate dentin sealing have significantly improved the success rates of restorations.
Immediate dentin sealing is a commonly known technique even outside of advanced adhesive and biomimetic restorative dentistry. Originally developed in the 1990’s to solve the issue of temporization contamination, its uses once refined were immense when applied to dentin adhesion. Yet for doctors currenting using immediate dentin sealing as part of their restoration protocols, there may be more benefits left untapped when not used as part of a larger system of protocols that aim to mimic the natural function of a tooth: the Six Lessons Approach to Biomimetic Restorative Dentistry.
Dr. Alleman discusses the history of immediate dentin sealing, its early pioneers and how doctors can use this technique in their own practice to save pulps and maximize adhesion.
