conical root; and there is seldom, if ever, enough

curvature of the roots to render extraction difficult.
The ordinary inferior-molar forceps arc not well

adapted to the purpose : for the central points of
their beaks will prevent a perfect adaptation. The
broad, single-concave beaked forceps are best adapted;
the curves and general forms of which, except the
beaks, are the same as those represented in Fig. 71.
The removal of teeth having this kind of roots is
easily accomplished. Rotary movement would be

applicable here, if the exact form of the root could be
ascertained before extraction; but it is, in general,
the safest course to employ the inward and outward
movement.

INFERIOR DENTES SAPIENTLE.

These teeth require, for their removal, the broad,
single-concave beaked forceps, the beaks curved at a
right angle with the handle, and the handle straight.
This instrument fixed deeply and firmly on the tooth,
the attachment is to be broken up by the inward and
outward movement. These, more frequently than

the superior dentes sapienticv, stand out of the proper
position ; their variations and the manner of obviating
the attendant difficulties, however, being about the
same—at least, so far as deviation is concerned.
