|
|
Overextensions on the gingival margin of a class 2 amalgam If very thin and accessible, maybe shaved off with________ |
Amalgam/gold knife |
|
|
True or false polishing devices are used from finer grit to coarser grit to eliminate surface scratches |
False use the course to fine |
|
|
True or false: Proper condensing of amalgam will eliminate voids reduce residual mercury and increased strength of the finished amalgam |
True' Please learn this one forwards and backwards |
|
|
Condensing the alloy immediately after titration. Prevents voids and allows each layer to bond together. True or false |
True PS learn this one forward and backwards |
|
|
By over filling the cavity preparation with amalgam, we are able to eliminate voids and adept margins. Allow the Mercury rich layers to be removed during carving and we are able to close the cavosurface margins properly. True or false |
True. Learn this one |
|
|
When condensing an amalgam into a preparation, choose the site that is__________ to fill first. |
Condense the least accessible area first |
|
|
Excess mercury left on the amalgam Restoration. Will do. What to the strength of the restoration? |
Will weaken the strength |
|
|
Amalgam is ready to carve when slight resistance is felt with a________ |
Carver |
|
|
The purpose of carving and amalgam is 1) to remove excess material from the cavo surface margin 2) to contour the restoration so it resembles the original contour 3) to remove a residual mercury. True or false? |
True. Learn this one |

Overlapping |
|
|
Grooves are placed on the occlusal surface of amalgam restorations with |
A pointed instrument |

|
Vertical angulation that is too steep when carving the occlusal surface of an amalgam restoration will... |
Provide a weak restoration (material too thin to have any strength to it) |
|
|
When checking the margins of a restoration, a catch is felt both from tongue to amalgam and from a amalgam to tooth. This is considered........ |
To be an open margin and restoration will need to be replaced |
