MULTIPLE CHOICE
1. What causes caries?
a. Food debris
b. Materia alba
c. Acidic foodstuff
d. Bacterial plaque
e. Salivary glycoproteins
CORRECT ANSWER: 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.

, 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
CORRECT ANSWER: 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.
