Plaque Consists Of

Question

Plaque consists of
A)an aggregation of all of the bacteria in the mouth.
B)a matrix of glycoproteins containing bacteria.
C)contaminant bacteria in the mouth.
D)the bacteria responsible for gum disease.
E)all of the above.

Accepted Answer

Plaque is a biofilm of bacteria that forms on teeth and other surfaces in the oral cavity. It is composed of a matrix of glycoproteins, which are produced by the bacteria themselves, that bind the bacteria to the tooth surface. While there are many different species of bacteria that can be found in plaque, it is not necessarily an aggregation of all the bacteria in the mouth. Additionally, not all of the bacteria found in plaque are necessarily contaminants, and while some types of bacteria can contribute to gum disease, not all plaque is necessarily comprised of these bacteria. Therefore, the most accurate answer is that plaque consists of a matrix of glycoproteins containing bacteria.
