THE TECHNICAX, PROCEDURES IN FILLING TEETH.

NOMENCLATURE.

NOMENCLATURE treats of systems of naming things. Den-
tal nomenclature treats of the terms, or names, used in den-
tistry. The subject is of first importance, for, if we do not know
the names by which things are called, we will be unable to under-
stand each other in speaking of them. Every profession, busi-
ness or trade, has its special system of naming things pertaining
to it, and this nomenclature must be understood before the stu-
dent can become proficient. In operative dentistry this system
of nomenclature is very simple and comprises but few words.
However, tliese words are used in a fairly wide range of combi-
nations that will be very perplexing to the student who has not
a good knowledge of them. He should understand them when
spoken by others and be able to use them freely and correctly
in his ordinary speech. Otherwise he will be unable to under-
stand his professors or fellow students as accurately as he
should, and thus find his studies more difficult than thej* other-
wise would be.
For the most part, the words are the same as those used in
Dental Anatomy, with which the student and every dentist
should be already familiar. But they are applied differently
and to different subjects. This new use now becomes a subject of
study as applied in cavity preparation and cavity nomenclature.
Cavity preparation includes all those operations required
in the removal of carious material from cavities formed in the
teeth by decay, forming the cavities for the reception of fillings,
and such extensions and preparations as will best fit the affected
surfaces of the teeth to resist decay in future.

Cavity Nomenclature,
illustrations: figures 114.
Rule: Cavities in the teeth take the names of the surfaces
of the teeth in which they occur.
We group cavities together according as the decayed sur-
faces are similarly situated. A further grouping may also be
made into classes, each class including those cavities that require
similar treatment.
