Glossary Entry: Dental Amalgam

Overview

Definition: Dental amalgam is a commonly used dental filling material composed of a mixture of metals, including mercury, silver, tin, and copper. It is known for its durability and effectiveness in restoring decayed teeth.

Detailed Description

Types and Variations

Variations: Different compositions of metals in dental amalgam may vary slightly, but the main components remain consistent for functional purposes.

Indications

Common Uses: Dental amalgam is typically used to fill cavities in the teeth caused by decay, providing a hard and long-lasting surface for chewing.

Insertion and Placement

Procedure: Dental amalgam is placed in layers into the prepared cavity and shaped to fit the tooth’s natural contours. The material hardens quickly, allowing the dentist to finish the restoration promptly.

Clinical Considerations

Potential Complications

Risks: There have been concerns about the potential release of mercury vapor from dental amalgam over time, although studies have shown minimal risk to patients.

Care and Maintenance

Maintenance Requirements: Dental amalgam fillings require no special maintenance beyond regular oral hygiene practices like brushing and flossing.

Additional Information

Related Devices

Associated Terms: Dental amalgam capsules, which contain pre-measured amounts of the mixture for easy dispensing during the filling procedure.

Innovations and Advancements

Recent Developments: Researchers continue to explore alternative dental filling materials to address concerns about mercury content in dental amalgam.

Regulatory and Safety Notes

Regulations: Dental professionals must follow strict guidelines for the safe handling and disposal of dental amalgam to minimize environmental impact.
