Summary
Newer dentin adhesive systems demonstrate superior clinical effectiveness compared to older ones. Optimal bonding involves smear layer removal, dentin demineralization, and an elastic bonding area for improved restoration longevity.
Area of Science:
- Dentistry
- Dental Materials Science
- Restorative Dentistry
Background:
- Laboratory testing of dentin adhesive systems needs long-term clinical validation.
- Earlier dentin adhesive systems require comparative clinical effectiveness evaluation.
Purpose of the Study:
- To retrospectively evaluate the clinical effectiveness of older dentin adhesive systems.
- To compare older systems with modern total-etch adhesive systems.
- To assess the impact of cavity preparation on clinical performance.
Main Methods:
- Retrospective clinical evaluation of 1177 Class V restorations in 346 patients.
- Comparison of six earlier dentin adhesive systems with four modern total-etch systems.
- Two cavity designs: Group A (no enamel etching) and Group B (beveled and conditioned enamel).
Main Results:
- Newer dentin adhesives showed significantly improved clinical retention rates over older systems.
- Adhesive systems removing the smear layer and demineralizing dentin performed better.
- Hybridization and resin tag formation are essential but may be insufficient alone.
Conclusions:
- Modern dentin adhesive systems offer superior clinical efficacy.
- Effective dentin bonding requires smear layer removal, dentin demineralization, and potentially an elastic bonding area.
- Long-term confirmation of excellent one-year retention for specific systems is needed.
