Summary
This study clinically evaluated four dentin bonding systems over two years. Systems that remove the smear layer and offer lining performed better than those that only modify it.
Area of Science:
- Dentistry
- Dental Materials Science
- Restorative Dentistry
Background:
- Dentin bonding systems are crucial for modern adhesive dentistry.
- Evaluating the long-term clinical performance of these systems is essential for material selection.
- The effectiveness of dentin bonding systems can depend on their interaction with the dentin smear layer.
Purpose of the Study:
- To clinically evaluate the performance of four different dentin bonding systems.
- To compare the longevity and efficacy of various adhesive systems in restoring Class V carious lesions.
Main Methods:
- Eighty Class V carious lesions were prepared and restored using four distinct dentin bonding systems.
- Restorations were assessed at baseline, 1 year, and 2 years post-placement.
- The US Public Health Service (USPHS) criteria were employed for clinical evaluation.
Main Results:
- No significant differences were observed among the four systems after one year.
- After two years, two of the tested adhesive systems demonstrated superior performance compared to the other two.
- Systems that actively remove the smear layer and provide a lining function outperformed those that merely modify the smear layer.
Conclusions:
- The long-term clinical success of dentin bonding systems is influenced by their mechanism of action on the smear layer.
- Adhesive systems with smear layer removal and lining capabilities show enhanced durability over a two-year period.
- Material selection should consider the specific properties of dentin bonding systems for optimal clinical outcomes.
