Summary
Glass-ionomer cements (GICs) are often overlooked for permanent posterior teeth due to perceived durability issues. However, studies show GICs exhibit similar long-term wear and retention compared to composite resins.
Area of Science:
- Dental Materials Science
- Restorative Dentistry
Background:
- Glass-ionomer cements (GICs) have been used since the 1970s for various dental applications.
- Their use as a direct restorative material, especially for permanent posterior teeth, is limited.
- Perceived limitations include esthetics and durability compared to composite resins.
Purpose of the Study:
- To evaluate the long-term clinical performance of GICs as a direct restorative material.
- To compare the wear and retention of GICs against composite resins in permanent posterior teeth.
Main Methods:
- Review of clinical studies comparing GICs and composite resins.
- Analysis of long-term wear and retention data.
Main Results:
- GICs demonstrate higher initial wear rates compared to composite resins.
- Despite initial differences, GICs show comparable long-term wear and retention over extended periods.
Conclusions:
- The perception of GICs being less durable than composites may not hold true for long-term clinical performance.
- GICs may be a viable restorative option for permanent posterior teeth, challenging current clinical perceptions.
