1. Caries is caused by:
A. food debris.
B. materia alba.
C. bacterial plaque.

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.

restoration.
C Ceramic veneer is a restoration that is constructed away from the patient in the
dental laboratory.
D Cast crown is a restoration that is constructed away from the patient in the dental
laboratory.
REF: Pg. 4
