Quiz Results and Correct Answers
1) The lingual matrix system:
- is fabricated after the restoration is removed
- needs to go two teeth past either side of the restoration
- facilitates pre-contouring of the lingual wall
- stops just short of the incisal edge
- creates more work and more inefficiency
2) The preparation for an invisible class IV restoration:
- should be a chamfer all around
- should be a long bevel
- is a butt joint
- makes no difference on the final aesthetic result
- should always break interproximal contact
3) The acid etching of the enamel and dentin:
- should be with a liquid phosphoric acid liquid
- is always self-limiting in depth
- is sequenced by loading the dentin first and then the enamel
- is done with multiple teeth all at once
- can be controlled with the proper gel etchant
4) The Class IV restoration:
- is completed using a microfil restorative material
- always needs an opaquer
- has a lingual enamel replacement of microfil only
- has a supportive structure of microhybrid
- is overfilled and then cut back
5) If shine through of the junction between the restorative material and tooth occurs:
- a corresponding colour of opaquer is placed over the shine through area
- a corresponding colour of opaquer is placed over the whole labial surface
- pink opaquer is used to hide the demarcation line
- not enough microfil has been used
- a white opaque is used to increase the value
6) The most important view of the restoration during the rebuilding process:
- is the labial view
- is the lingual view
- is the interproximal view
- is the incisal view
- does not matter
7) When placing the violet tint or gray tint to mimic incisal translucency:
- it is placed so that you can easily see it
- it is placed over the occlusal white lingual shelf
- it is placed between the microfil body and incisal translucent shade
- it can be left on the surface
- does not matter where you place it as long as it is covered
8) When developing the labial anatomy:
- place the mesial and distal walls out to the edges
- scallop the labial surface to create proper anatomy
- use polishing points to blend the lobes carefully
- use fine polishing discs so as not to flatten the labial surface
- all of the above
