Periapical radiograph showing peri-radicular radiolucency and bone loss caused by an odontogenic infection under the roots of two anterior teeth in a 30-year-old patient An odontogenic infection is an infection that originates within a tooth or in the closely surrounding tissues. [ 1 ]
A dental abscess is a localized collection of pus associated with a tooth. The most common type of dental abscess is a periapical abscess, and the second most common is a periodontal abscess. In a periapical abscess, usually the origin is a bacterial infection that has accumulated in the soft, often dead, pulp of the tooth.
A cutaneous sinus of dental origin is where a dental infection drains onto the surface of the skin of the face or neck. This is uncommon as usually dental infections drain into the mouth, typically forming a parulis ("gumboil").
Dental conditions such as gum disease, periapical abscesses, or tooth decay can lead to odontogenic sinusitis. Similarly, dental procedures such as tooth extractions, implant placement, or root canal treatments, particularly if they involve the posterior maxillary teeth, can also cause this condition.

Intraoral dental sinus (also termed a parulis and commonly, a gumboil) is an oral lesion characterized by a soft erythematous papule (red spot) that develops on the alveolar process in association with a non-vital tooth and accompanying dental abscess. [1] A parulis is made up of inflamed granulation tissue.
A phoenix abscess is an acute exacerbation of a chronic periapical lesion. It is a dental abscess that can occur immediately following root canal treatment. Another cause is due to untreated necrotic pulp (chronic apical periodontitis). [1] It is also the result of inadequate debridement during the endodontic procedure.
An abscess is a localized collection of pus which forms during an acute infection. The important difference between a periapical abscess and abscesses of the periodontium are that the latter do not arise from pulp necrosis. [12] Abscesses of the periodontium are categorized as gingival abscess, periodontal abscess and pericoronal abscess.
