What instruments are used for amalgam fillings?
Restorative dental hand instruments include the amalgam carrier, burnisher, condensers, composite placement instruments, carvers, and Woodsen.
- Amalgam Carrier – used to carry an increment of amalgam directly into the prepared tooth.
- Burnisher – used to smooth the surface of a freshly placed amalgam restoration.
What are the uses of amalgam condenser?
a·mal·gam con·den·ser. Instrument used to impress unset amalgam into a cavity preparation of a tooth. Synonym(s): amalgam plugger.
What causes amalgam discoloration?
Amalgam fillings often stain the tooth they are placed in. This is most noticeable in very old fillings, as pigment slowly leaches out of the amalgam filling material and its associated corroded surfaces. In addition, metallic fillings cast a shadow that can be visible through the tooth and make it appear darker.

Why is the amalgam capsule reassembled immediately after use?
The amalgam capsule is reassembled immediately after use to: save the extra amalgam for later use. minimize mercury escaping into the air. prepare the capsule for reuse.
Why do we polish amalgam after 24 hours?
Polishing after 24 hours produced a significantly smoother surface for both amalgam alloys on both the simulated proximal and occlusal surfaces. 2. The standard polishing procedures after 24 hours produced a smoother surface than any of the immediate finishing procedures tested.

Which mirror do dentists use?
concave mirror
A concave mirror gives the dentist a magnified reflection of the mouth while also refracting a bit of light. This means the image in the mirror is larger, brighter, and, for the dentist, easier to see.
Where do you place the band on an amalgam?
The band should be seated around the tooth such that: 1. The occlusal portion of the band extends 1.5 – 2.0 mm above the marginal ridge of the adjacent tooth and the cavosurface margin–this allows for proper condensation of the amalgam in the marginal ridge area. 2. The gingival portion of the band extends 0.5 mm below the gingival CSM.
What is matrix placement for Class II amalgam restoration?

Why are amalgam restorations important to dental health?
Placement of amalgam restorations is just one aspect of achieving and maintaining optimal dental health. When teeth are restored with amalgam restorations, those restorations must not detract from the health of the teeth and the surrounding tissues.
How to reduce the mercury content of amalgam?
• The most obvious method to reduce mercury content is minimal mercury technique or eames technique (mercury:alloy=1:1) ,in which sufficient mercury should be present to form coherent and plastic mass after trituration. The mercury content of the finished restoration should be comparable to the original mercury/alloy ratio usually 50 wt% 3.
