CHRONIC ABSCESS

which pus formation is fully established, the tissues of the
pulp are largely broken up, and the apical tissue has been
destroyed to a point where an abscess cavity is present in
that locality, while the acute symptoms of pain, tenderness
and swelling have largely subsided. (See Figs. 264 to 290
inclusive.)
There are two varieties of Chronic Alveolar Abscess, viz
1. Abscess without sinus; the pus discharging via the root
canal (false blind abscess), or being absorbed via the lym-
phatics and the blood streams (true blind abscess).
2. Abscess with sinus ; the pus having bored its way through
the overlying bone and opening externally.
Dangerous conditions are liable to arise from masked
cases of chronic abscess without sinus. Local foci of infection
may be established, in which the pus and toxic products are
slowly absorbed via the lymphatics and blood streams, pro-
ducing general depression of the metabolic functions of the
system, and resulting in lowered vitality, infections in other
I parts, loss of vigor, sleeplessness, anorexia, anaemia, leu-
kaemia, intestinal disturbances, rheumatism, arthritis and
vague disturbances of internal organs.
Treatment.—Open the chamber and canals under aseptic
precautions, remove the contents, evacuate the pus by pres-
sure over the apex of the tooth and swabbing of the canals.
Dry the chamber and canals and seal in formo-cresol, modified
formo-cresol or other antiseptics. Repeat the treatment
frequently, sometimes daily, until the pus flow stops; then
seal in a mild, antiseptic, anodyne treatment for a week or
ten days; then, if the case is healed, as evidenced by stoppage
of discharge, disappearance of all odor, tenderness and other
symptoms, the canals may be filled. Over-treatment, or too
frequent treatment will sometimes result in the prolonged
continuance of a serumal discharge, which is not pus. In
