Summary
This study evaluated the biocompatibility of a third-generation dentinal adhesive (Scotchbond 2). While initial reactions were observed, they decreased over time, suggesting good biocompatibility with proper clinical application.
Area of Science:
- Dental Materials Science
- Biocompatibility Testing
- Restorative Dentistry
Background:
- Third-generation dentinal adhesives are crucial for dental restorations.
- Understanding their biocompatibility is essential for clinical success.
- Scotchbond 2 utilizes a smear layer conditioner.
Purpose of the Study:
- To assess the in vivo biocompatibility of a third-generation dentinal adhesive, Scotchbond 2.
- To evaluate the histological response to the adhesive in human premolars.
- To determine the effect of smear layer conditioning on biocompatibility.
Main Methods:
- Class V cavities were prepared and restored in 32 human premolars.
- Restored teeth were extracted for histological examination (short-term and long-term).
- Standardized protocol and histological observation were employed.
Main Results:
- Histologic observations revealed transient inflammatory reactions (slight, moderate, severe).
- The intensity of inflammatory reactions decreased over time.
- No correlation was found between bacterial presence and reaction severity.
Conclusions:
- Scotchbond 2 demonstrates acceptable biocompatibility, with reactions diminishing over time.
- Smear layer conditioning may enhance adhesion and limit percolation.
- Clinical use necessitates a protective lining near the pulp to mitigate potential severe reactions.
