BASIC TERMINOLOGIES Flashcards

1
Q

This is defined as the study of the development,
morphology, function, and identity of each
of the teeth in the human dentitions, as
well as the way in which the teeth relate in
shape, form, structure, color, and function
to the other teeth in the same dental arch
and to the teeth in the opposing arch.
