POLISHING FILLINGS 187

(b) Polish, first with garnet and then with cuttle-fish disks,
in locations where these will readily reach, finally going over
the surface, if a specially high finish is desired, with crocus
disks, or with chamois, felt, or moose-hide buffers, dipped in
whiting or rouge. In pits and fissures, where the disk is
not applicable, after the final shaping of the filling, the sur-
face may be gone over with finishing burs, which will give
a high burnish; or, if preferred, the use of wood points and
wet pumice may be resorted to, finally going over the sur-

2. Fillings in Proximal Cavities, (a) The Gingival Por-
tion.—After thorough burnishing (Fig. 211), the excess at the
gingival portion, up to a point slightly gingival to the con-
tact point, is first removed by means of a saw in a Wilson or
Kaeber saw frame, or by the use of keen Pichler or Black
knives. This portion is then gone over with the Black
files, or the Rhein approximal trimmers until the filling is
flush with the gingival margin (Figs. 212 and 213).
