better to use the special lower
molar forceps as shown in Figs.
485 and 498.
Fig. 490 and Fig. 491 rep-
resent very useful forceps for
extracting the ten upper an-
terior teeth. Fig. 491 has
longer beaks and its points are
finer. In skillful hands where
too grreat a force will not be
brought to bear on the points
they are the better forceps.
Under nitrous oxid and where
many teeth are to be extracted,
thus requiring rapid work, the
instrument shoMn in Fig. 490
is preferable.
Figs. 492 and 493, right and
left, represent forceps specially
used for extracting the first and
second upper molars on either
side. The outer beak is made
pointed for the purpose of pass-
ing in between the buccal roots,
the inner beak is concave in
order to gras}) the palatal root.
Figs. 495 and 496 show bayonet-
shaped forceps, that illustrated
by Fig. 495 being especially
made for extracting the upper
third molars, Fig. 496 being
used for upper roots. The ends
of the handles of all forceps
which are forced in by the palm
of the hand should have a broad
surface as shown in Fig. 496.
These forceps are popular with
many operators. The writer
considers them clumsy, as they
obscure the proper view of the
