GAINING ACCESS 33

mediate separation is brought to our attention during the introduc-
tion of the filling.
Preliminary Separation is best accomplished in proximal cavities
in bicuspids and molars (Class Two) by packing into the partially
excavated cavity an excess of gutta-percha base plate. A few days,
or in some instances a few weeks, will suffice to accomplish the
desired result, particularly if the patient uses that location in the
mouth for daily mastication of solid food.
In the proximal space in the six anteriors preliminary separa-
tion is best accomplished by the use of cotton tampons tightly
packed in the cavity and ligatured securely to position.
Immediate Separation is best accomplished with the mechanical
separator, and should be used to gain additional access, not already
secured by preliminary separation, or may be used primarily when
only a small amount of additional space is desired. This instru-
ment should be adjusted as soon as convenient after securing out-
line form, and removed only when the filling is finished.
Avoid Gum Injuries in the use of elastic rubber. In the use of
the methods given care should be used not to croAvd the gum tissue
as permanent injury may result.
There are other materials used in slow separation, as linen tape,
"^vooden wedges, etc., each with its merit and indicated use.
Soreness Resulting from Tooth Separation should be treated as
any case of acute pericementitis, by giving the tooth physiological
rest, and the use of stimulating applications on the gum over the
tooth's root.
