Summary
Silver amalgam remains a viable material for specific dental restorations, but its use is now restricted. Dentists should reserve amalgam for cases where it offers distinct advantages over other materials.
Area of Science:
- Dental Materials Science
- Restorative Dentistry
Background:
- Silver amalgam is a traditional material for direct intracoronal restorations in posterior teeth.
- This review examines the current role of amalgam in light of its properties, alternatives, and regulations.
Purpose of the Study:
- To evaluate the continued use of silver amalgam in restorative dentistry.
- To establish criteria for appropriate applications and contraindications of amalgam.
Main Methods:
- Review of consensus views on amalgam use.
- Analysis of toxicity, financial, and legislative aspects.
- Comparison with competing restorative materials.
Main Results:
- Silver amalgam has a restricted but continuing place in dental practice.
- Amalgam use is justified only when it presents clear benefits over alternatives.
Conclusions:
- The judicious use of silver amalgam is supported pending the development and optimization of superior substitutes and comprehensive training in adhesive techniques.
