Summary
Modern dentin bonding agents achieve reliable bond strengths to dentin, comparable to enamel. State-of-the-art systems are now technique insensitive and function in moist environments.
Area of Science:
- Dental Materials Science
- Adhesive Dentistry
Background:
- Achieving a reliable adhesive bond between dental tissues (enamel, dentin) and restorative materials is a long-standing goal in dentistry.
- Early generations of dentin bonding agents exhibited inconsistent bond strengths.
- Advancements have led to systems with improved performance.
Purpose of the Study:
- To review the evolution and current criteria for state-of-the-art dentin bonding systems.
- To highlight key properties of advanced dentin bonding agents.
Main Methods:
- Review of historical and current literature on dentin bonding agents.
- Analysis of bond strength data and ideal properties for dental adhesives.
Main Results:
- Current dentin bonding systems demonstrate in vitro shear bond strengths to dentin that rival those to enamel.
- Ideal properties now include functionality in moist conditions and reduced technique sensitivity.
Conclusions:
- Modern dentin bonding systems have significantly improved, offering reliable adhesion.
- Technique insensitivity and moist environment compatibility are crucial for contemporary dentin bonding agents.
