NAPHTHOL.
^'ji
posed to be a form of b naphthol, is not well known. It is in the
form of light fawn-colored crystalline flakes, having a feeble odor
and taste. As a germicide, it apparently possesses the power of pre-
venting the development of germs and their spores. It resembles
capsicum, in possessing slight stimulating and counter-irritant
properties, but is not so powerful.
Dental Uses,—Hydronaphthol is employed for treating the
canals of pulpless teeth, pericemental inflammation of septic origin,
especially in the eaHy stages before pus has formed. Dr. Jas.
Truman recommends a solution of i : looo of water for injection
into pulp-canals; and Dr. E. C. Kirk recommends a paste of
hydronaphthol and glycerine, pumped into a thoroughly cleansed
pulp-canal in pericemental inflammation from septic causes, to
it should
remove the soreness and inflammation in a few hours ;
be retained by a temporary filling of gutta percha. It is also
recommended as an ingredient for a mouth wash for diseased
gums and mucous membrane.
Alpha-oxynaphthoic acid (or alpha-naphthol-carbonic acid) is pre-
pared in a similar manner to salicylic acid, naphthol being substi-
tuted for phenol. Its formula is CmHg,COOH. It is obtained
by bringing together, under strong pressure, and at an elevated
temperature, alpha-naphthol, sodium and carbonic acid gas. It
is nearly insoluble in water, but soluble in the alkalies and alka-
line carbonates, forming salts, which are colorless and of neutral
reaction, and more soluble in hot and cold water than the acid
itself. It is antiseptic and germicide, experiments upon bacteria
giving favorable results.
