Oral Surgery


The parulis or "gum boil" appears as a soft solitary, reddish papule located facial and apical to a chronically abscessed tooth.

It occurs at the endpoint of a draining dental sinus tract.

Acute swelling and pain may result if the sinus tract is obstructed, but symptoms temporarily are relieved when pus escapes to the surface.

Treatment of a parulis in a child consists of diagnosing which tooth is abscessed with clinical examination and a periapical radiograph and extracting the tooth or performing complete pulpectomy.

The treatment of choice depends on the prognosis of successful pulpal therapy and the strategic importance of the tooth.

Regression of the parulis usually occurs shortly thereafter. If the offending tooth is left untreated, the parulis may persist for years or mature into a pink fibroma.

Eruption Cyst and Hematoma

Eruption cysts are associated with erupting primary and permanent teeth. They present as dome-shaped soft-tissue lesions overlying any erupting tooth in children.

The eruption cyst results from fluid accumulation within the follicular space of an erupting tooth.

When the fluid in the cyst is mixed with blood, the cyst is referred to as an eruption hematoma.

No treatment is needed because the tooth erupts through the lesion, which disappears spontaneously.
