For softened and sensitive dentine, and for drying cavities pre-
paratory to filling them, the stronger or absolute alcohol is em-
ployed. The spray of absolute alcohol is employed as a local
anaesthetic, and is applied in the same manner as the spray of
rhigolene. A simple method of preparing this form of alcohol
is to add one part of carbonate of potassa to four parts of the
ordinary or officinal alcohol. Owing to the great affinity car-
bonate of potassa has for water, it abstracts the latter from the
alcohol to a sufficient degree to answer all practical purposes.
The cavity of a tooth is first dried with cotton and bibulous
paper, and then bathed with the absolute alcohol, which at once
evaporates, and causes the almost perfect absorption of moisture.
Brandy and water form, in combination, an excellent lotion
for mercurial and other forms of stomatitis.
