The Mucinous Glycoprotein Covering Teeth That Streptococci Attach to Is

Question

The mucinous glycoprotein covering teeth that streptococci attach to is called the ________.
A)enamel
B)pellicle
C)gingiva
D)lactoferrin
E)oral membrane

Accepted Answer

The mucinous glycoprotein layer that covers teeth is called pellicle, and it is the primary site for bacterial attachment in the oral cavity. Streptococci are known to bind to the pellicle to form dental plaque. Enamel is the hard outer layer of the tooth, while gingiva refers to the gum tissue surrounding the teeth. Lactoferrin is a protein found in saliva and mucous secretions, and the oral membrane is not a recognized term in this context.
