The Greatest Proportion of the Tooth Shell Consists Of

Question

The greatest proportion of the tooth shell consists of:
A)enamel.
B)dentin.
C)gingivae.
D)cementum.

Accepted Answer

The greatest proportion of the tooth shell consists of dentin, which makes up the bulk of the tooth structure. Enamel is the hard, outer layer covering the crown of the tooth, but it only makes up a small proportion of the tooth. Gingivae refer to the gums, which surround and support the tooth but are not part of the tooth structure itself. Cementum is a thin layer covering the roots of the tooth, but again, it only makes up a small proportion of the tooth.
