1. What causes caries?
ht ht


a. Food debris ht


b. Materia alba ht


c. Acidic foodstuff ht


d. Bacterial plaque ht


e. Salivary glycoproteins ht




ANS: D ht




Feedback
A Food debris does not have the structural organization of
ht ht ht ht ht ht ht ht


bacterial plaque biofilm.
ht h t ht

B Materia alba does not have the structural organization of
ht ht ht ht ht ht ht ht


bacterial plaque biofilm.
ht h t ht


C Acidic foodstuff lowers pH and may demineralize teeth but does
ht ht ht ht ht ht ht ht ht


not directly cause decay.
ht h t ht ht


D Caries is caused by biofilm; also known as bacterial plaque.
ht ht ht ht ht ht ht ht ht


E Salivary glycoproteins form the acquired enamel pellicle to
ht ht ht ht ht ht ht


which bacteria adhere.

less surface area left unchecked.
