for years. Particularly is this true when the pink variety has been
employed and the method of introduction is correct.
Fig. 296.
Mode of Softening-.—Gutta-percha should never
be heated beyond a point which permits of accurate
adaptation to undercuts and frail walls. The soften-
ing should be gradual. Any heat in excess of this is
not only harmful but ruinous.
For its proper softening some device is necessary
which shall permit of this type and degree of heating
(see Figs. 295-297, 306).
Fig. 295 illustrates the heater of Dr. Flagg. There
are three metallic shelves, the highest of which receives
the least amount of heat, and is designed for softening
low-heat gutta-percha. The second shelf is for the
softening of high-heat specimens. The lowest shelf
and rack support the packing instruments, which are
kept at a higher temperature than the filling material.
Fig. 296 illustrates a device of Dr. L. A. Faught
for the packing of gutta-percha. The heating wires
connect at the bases of the instrument points, which
are of aluminum, and sufficient heat is conveyed to the
gutta-percha to maintain it in a plastic state during the
packing operation.
Instruments.—As a rule the instruments used in
packing gutta-percha are too large and the material
itself is used in too large pieces. If the cavity is of
considerable extent, and usually it is, the filling should
be introduced in four or more pieces. It is preferable
to warm all the packing instruments so that the gutta-
percha will remain plastic until perfectly adapted.
Manipulation.—The rubber dam having been ad-
justed, the cavity excavated and sterilized, the frail
enamel edges broken away, without p„. 297.
