378 EXTRACTION OF TEETH.

ceps have narrow, thin, sharp beaks, turned to almost

a right angle. With them, the root is embraced, and
moved inward and outward till loosened, and then
removed. When the mouth is large, and can be
opened wide, the slightly curved root forceps are
convenient, and the rotary movement may be em-
ployed with them, if the roots are not very much
curved, flattened, or firmly set The removal of
these roots is more difficult when the bifurcation is
low down, and the roots remain firmly attached

together, and especially when they diverge. If the
bifurcation is not too low, and the attachment not too
firm, the roots may be separated with the separating
forceps (Fig. 85), and then removed singly, as in
other cases. This is the preferable method, when

there is much divergence ; but if the fangs can not
be separated, they may be extracted with the forceps
shown in Fig. 74. The round, curved, sharp beaks

are passed down between the roots, and the whole is
removed at once ; the attachment being broken up on

the principle already described.
These teeth sometimes have but one, large, round,
