#Sudden relief of severe pain associated with a dentoalveolar abscess can be explained by which of the following?
A. Neutralizing effect of tissue enzymes
B. Walling-off of the infection by the body
C. Rupture of the abscess from the periosteum into the soft tissue

The correct answer is C. Rupture of the abscess from the periosteum into the soft tissue.

Dentoalveolar abscesses are an accumulation of pus within the teeth, gums,
and supporting alveolar bone.

The accumulation of pus within the
dentoalveolar abscess creates hydrostatic
pressure, resulting in the sensation of a
severe pain.

Dentoalveolar abscesses are treated
through root canal treatment and possibly
incision and drainage depending upon case
severity.

Drainage of the lesion releases the pressure
caused by the suppuration and results in a
sudden relief of pain is experienced by the
patient.

The major symptom of dentoalveolar
abscess is a severe, intense, and throbbing
pain which worsens with the passage of
time.

Dentoalveolar abscesses can be partially
diagnosed by noting the presence of a
periapical radiolucency.
