a. Patients with bruxism or clenching habits.
b. Teeth with deep caries lesion
c. All of the above
d. None of the above Answer - a. Patients with bruxism or clenching habits.
- Poor strength of crowns may fracture in patients with bruxism or reduced
inter-occlusal clearance
Following are common causes of failure of indirect restoration except:
a. poor preparation design/shape resulting in lack of retention and/or
resistance form
b. insufficient reduction or lack of support/thickness for ceramic or composite
c. None of the above
d. failure to identify and/or correct occlusal problems Answer - c. None of the
above
- Any tooth preparation for a crown should follow the appropriate
biomechanical principles
Gold can be used in thin sections and it is highly aesthetic. One millimeter of
tooth reduction is required occlusally, with the exception of the functional cusp
bevel where 1.5 mm is necessary.
,a. First statement is FALSE and second statement is TRUE
b. First statement is TRUE and second statement is FALSE
c. BOTH statement are FALSE
d. BOTH statements TRUE Answer - a. First statement is FALSE and second
statement is TRUE
- Gold can be used in thin sections but it is not highly aesthetic.
Porcelain laminate veneers may also be used to correct peg-shaped lateral
incisors, to close proximal spacing and diastemas, to repair (some) fractured
incisal edges, and to align labial surfaces of instanding teeth
a. TRUE
b. FALSE Answer - a. TRUE
- Porcelain laminate veneers used to correct pegshaped lateral incisors, to close
proximal spacing and diastemas, to repair (some) fractured incisal edges, and
to align labial surfaces of instanding teeth.
Computer-aided design and manufacture techniques (CAD-CAM) are capable of
producing accurately fitting inlays from blocks of ceramic material. Composite

using a mixture of heat and pressure, and heat and light.

A patient arrives at your office with their full gold crown in hand. They explain
to you that another dentist delivered it just last week. You then examine the
crown and the preparation. What is most likely reason the crown fell off?
a. There was very little cement in the crown
b. The preparation was only 4 mm high
c. The preparation walls were tapered at about 15°
d. The margins were jagged and undefined Answer - c. The preparation walls
were tapered at about 15°
- Taper provides the optimal friction between the walls and the casting, which
is the main retention. The ferrule/height of the preparation also provides the
friction, thus, retention, but 4mm is enough (minimal: 3mm)
The most retentive style of pins is the self-threaded pins because they are
cemented into pinholes that are smaller than the pin itself.
a. Both statement and the reason are correct and related
b. Both the statement and the reason are correct but not related
c. The statement is correct, but the reason is not
d. The statement is not correct, but the reason is correct
e. Neither the statement nor the reason is correct Answer - c. The statement is
correct, but the reason is not
- Although the pinhole is smaller than the selfthreaded pin, it is NOT cemente
