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.
