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.

CORRECT ANSWER: 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.

D. A ceramic inlay on tooth number 14 is an example of an intracoronal restoration, meaning that the
pl
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
CORRECT ANSWER: 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.
