1. What causes caries?
k k



a. Food debris k



b. Materia alba k



c. Acidic foodstuff k



d. Bacterial plaque k



e. Salivary glycoproteins k




ANS: D k




Feedback
A Food debris does not have the structural organization of bacterial
k k k k k k k k k



kplaque biofilm. k


B Materia alba does not have the structural organization of bacterial
k k k k k k k k k



kplaque biofilm. k



C Acidic foodstuff lowers pH and may demineralize teeth but does not
k k k k k k k k k k



kdirectly cause decay. k k



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



E Salivary glycoproteins form the acquired enamel pellicle to which
k k k k k k k k



kbacteria adhere. k

krestoration, meaning that the restoration is being used to repair k k k k k k k k k



kdamage restricted to the internal parts of a tooth. Materials such as
