some cases very promptly : take Canada balsam and
slacked lime, and, having made them into a paste, fill
the cavity partially full with it, and permit it to re-
main until the object is accomplished.
The sensitiveness of dentine may be obtunded by
thorough friction on the affected part with a smooth
burnisher. This method, however, is applicable only
to those cases in which there is room to use the in-
strument. On the surfaces of the teeth, where there
may be sensitiveness, it is very applicable and very
efficient. Simple pressure, without friction, it is sug-
gested, will accomplish the same object ; though
pressure and friction combined, are doubtless more
efficient.
