MULTIPLE CHOICE
1. Caries is caused by:
A. food debris.
B. materia alba.
C. bacterial plaque.
D. salivary glycoproteins.
E. acidic foodstuff.
ANS: C
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 Caries is caused by bacterial plaque.
D Salivary glycoproteins form the acquired enamel pellicle to which bacteria adhere.
E Acidic foodstuff lowers pH and may demineralize teeth but does not directly cause decay.
REF: Pg. 1
2. Caries is most likely to occur on which of the following tooth surfaces?
A. Buccal
B. Lingual
C. Occlusal
D. Interproximal
E. C and D
ANS: 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.
E Caries is most likely to occur in pits and fissures on the occlusal surface and on interproximal tooth surfaces where plaque accumulates unchecked.
