Why do self etch bonding systems tend to have less post operative sensitivity?
- A . Self etch bonding does not remove the smear layer but modifies it, leaving the smear plugs intact
- B . Self etch products remove & replace the smear layer
- C . Self etch bonding removes collagen fibrils and replaces them with resin plugs
- D . Self etch systems etch and bond simultaneously
In restoring multiple anterior teeth with ceramic restorations, the desired incisal plane can BEST be communicated to the laboratory by:
- A . Paralleling the incisal edges of the preparations.
- B . Indicating the incisal plane on the diagnostic cast.
- C . Including the patient’s photograph with the lab prescription.
- D . Paralleling the unprepared mandibular incisal plane.
There is a direct relationship between the f-stop and depth of field.
Which is correct?
- A . Larger f-stop, larger depth of field
- B . Larger f-stop, smaller depth of field
- C . F-stop equals depth of field
- D . F-stop decreases depth of field
What is the BEST property of condensible composites?
- A . Lower filler content to allow lateral and vertical flow ensuring intimate contact
- B . Less stickiness and stiffer consistency and have a wear ratio similar to amalgam
- C . A filler loading of fibrous, porous, or irregular particles, and a filler percentage of 40% to 50% filled
- D . Clinical evidence of strength and polymerization shrinkage superior to conventional composites
A patient would like to brighten her smile in addition to restoring her missing tooth #8. however, she is not interested in dental implants. She would also like to close the spaces between her existing teeth. Unfortunately, due to financial concerns she can only restore teeth ##7-10.
Reviewing the photograph above, how would you achieve golden proportion?
- A . Fabricating a three-unit bridge and a single veneer on tooth #10 will easily achieve golden proportion
- B . In office bleaching along with direct bonding on teeth ##7, 9, and 10, and a Maryland bridge to replace tooth #8 will easily achieve golden proportion
- C . Direct resin bonding in conjunction with a removable partial denture will achieve golden proportion
- D . It is impossible to achieve golden proportion unless more teeth are restored
Which of the following anatomical characteristics regarding the lips is correct?
- A . Lip morphology has little to do with bones and teeth
- B . Lips plump and drop with aging
- C . The philtrum of the lip is an accurate anatomical guide to the center of the face
- D . As one ages, the philtrum of the lip becomes more dominant
With acetone based adhesive systems, the strength of adhesion to dentin after etching with phosphoric acid can be increased by:
- A . Removing the smear layer to eliminate all surface debris.
- B . Drying the dentin completely.
- C . Treating the dentin with 10% NaOCI (sodium hypochlorite) and keeping it moist.
- D . Keeping the dentin moist.
Which of the following would be the main advantage of utilizing a layering technique with composite resin in restoring a disto-occlusal Class II restoration?
- A . Higher degree of polymerization and lower degree of tooth sensitivity
- B . Higher sheer strength and wear resistance
- C . Higher tensile strength and modulus of elasticity
- D . Better compressive strength
At home bleaching treatments are MOST effective for:
- A . Treatment of mild tetracycline discoloration.
- B . Treatment of trauma induced staining.
- C . Age-related discoloration.
- D . Mild to dark surface staining.
When determining the shade of a tooth, once the tooth becomes desiccated, it:
- A . Decreases in value.
- B . Becomes more translucent.
- C . Increases in value.
- D . Increases in chroma.
