Summary
Dental adhesion remains challenging despite advances since 1955. Micromechanical bonding, involving adhesive monomer penetration into collagen fibers, is key for effective dentin bonding strategies.
Area of Science:
- Operative Dentistry
- Biomaterials Science
- Dental Adhesion
Background:
- Since 1955, operative dentistry principles have evolved with new adhesive techniques.
- Dentin adhesion remains a significant challenge in clinical practice.
- Micromechanical bonding, through adhesive monomer penetration into collagen fibers, is crucial for dentin bonding.
Purpose of the Study:
- To review the challenges and strategies in dentin adhesion.
- To highlight the importance of micromechanical bonding in modern dentistry.
- To compare self-etch and total-etch techniques in bonding to enamel and dentin.
Main Methods:
- Review of historical and current adhesive techniques in dentistry.
- Discussion of the role of collagen fibers and monomer penetration in dentin bonding.
- Analysis of the influence of dentin substrate on bonding strategy efficiency.
Main Results:
- Dentin adhesion is primarily achieved through micromechanical bonding.
- The choice of bonding strategy (self-etch vs. total-etch) is substrate-dependent.
- Laboratory tests on ideal dentin do not fully represent clinical outcomes.
Conclusions:
- Effective dentin bonding relies on understanding micromechanical principles.
- Clinical studies are essential for validating the efficacy of dental adhesive materials.
- Adhesive dentistry continues to evolve, with ongoing challenges in achieving reliable dentin adhesion.
