MULTIPLE CHOICE
1. What causes caries?
a. Food debris
b. Materia alba
c. Acidic foodstuff
d. Bacterial plaque
e. Salivary glycoproteins
ANS: D
Feedback
A Food debris does not have the structural organization of bacterial plaque
biofilm.
B Materia alba does not have the structural organization of bacterial plaque
biofilm.
C Acidic foodstuff lowers pH and may demineralize teeth but does not directly
cause decay.
D Caries is caused by biofilm; also known as bacterial plaque.
, E Salivary glycoproteins form the acquired enamel pellicle to which bacteria
adhere.

2. Caries is most likely to occur on which of the following tooth surfaces?
a. Buccal
b. Lingual
c. Occlusal
d. Interproximal
e. C and D are both correct.
ANS: E
Feedback
A Buccal surfaces are also susceptible to caries; however, there is less surface
area left unchecked.
B Lingual surfaces are also susceptible to caries; however, there is less surface
area left unchecked.
C Caries is most likely to occur in pits and fissures on the occlusal surface and on
interproximal tooth surfaces where plaque accumulates
unchecked.
D Caries is most likely to occur in pits and fissures on the occlusal surface and on
interproximal tooth surfaces where plaque accumulates unchecked.
E Caries is most likely to occur in pits and fissures on the occlusal surface and on
interproximal tooth surfaces where plaque accumulates unchecked.

3. Which of the following is an intracoronal restoration?
a. Ceramic–alloy crown on tooth number 21
b. Ceramic veneer on tooth number 8
c. Ceramic onlay on tooth number 30
d. Ceramic inlay on tooth number 14
ANS: D
Feedback
A The alternate choices are all extracoronal restorations used to repair the
external.
B The alternate choices are all extracoronal restorations used to repair the
external.
, C The alternate choices are all extracoronal restorations used to repair the
external.
D A ceramic inlay on tooth number 14 is an example of an intracoronal
restoration, meaning that the restoration is being used to repair damage
restricted to the internal parts of a tooth. Materials such as amalgam and
composite resin are used in addition to ceramic or cast metal.

4. What is the process called where decay is removed from the tooth in order for a restoration
to be placed?
a. Cavity preparation
b. Convenience form
c. Margination
d. Extension
ANS: A
Feedback
A The process is referred to as cavity preparation. Cavity preparation is used to
remove diseased or damaged tissue and provide a space accessible for
restoration and one that can stably retain the restoration.
B Convenience form is a term describing the nature of the cavity
preparation.
C Extension is a term describing the nature of the cavity preparation.
D Margination is the procedure for finishing the margins of a restoration.

5. Which of the following is an example of an intracoronal (direct) restoration?
a. Laboratory-cured composite
b. Dental amalgam
c. Ceramic veneer
d. Cast crown
ANS: B
Feedback
A Laboratory-cured composite is a restoration that is constructed away from the
patient in the dental laboratory.
B Dental amalgam is an example of a direct restoration. All of the other
restorations are prepared away from the tooth and then cemented or bonded
to the tooth using a procedure that is independent of the manufacturer of the
restoration.
C Ceramic veneer is a restoration that is constructed away from the patient in
the dental laboratory.
