Periodontal abscess—a localized, purulent infection involving a greater dimension of the gum tissue, extending apically and adjacent to a periodontal pocket. [ 3 ] Pericoronal abscess —a localized, purulent infection within the gum tissue surrounding the crown of a partially or fully erupted tooth. [ 3 ]
External drainage may begin as a boil which bursts allowing pus drainage from the abscess, intraorally (usually through the gum) or extraorally. Chronic drainage will allow an epithelial lining to form in this communication to form a pus draining canal . [3] Sometimes this type of drainage will immediately relieve some of the painful symptoms ...
Incision and drainage (I&D), also known as clinical lancing, are minor surgical procedures to release pus or pressure built up under the skin, such as from an abscess, boil, or infected paranasal sinus.
Generally, the abscess can be eradicated through surgical drainage alone; however this is sometimes inadequate. Therefore, systemic antibiotic treatment may be required, but only if there is evidence of spreading infection. [9] As the bacteria involved are known, antibiotic therapy selection can be specific, based on published susceptibilities. [9]
Periapical periodontitis may develop into a periapical abscess, where a collection of pus forms at the end of the root, the consequence of spread of infection from the tooth pulp (odontogenic infection), or into a periapical cyst, where an epithelial lined, fluid-filled structure forms.
Abscess five days after incision and drainage Abscess following curettage. The abscess should be inspected to identify if foreign objects are a cause, which may require their removal. If foreign objects are not the cause, incising and draining the abscess is standard treatment. [4] [32]
A general principle concerning dental abscesses is ubi pus, ibi evacua ("where there is pus, drain it"), which applies to any case where there is a collection of pus in the tissues (such as a periodontal abscess, pericoronal abscess, or apical abscess). The pus within the abscess is under pressure, and the surrounding tissues are deformed and ...
Tooth #5, the upper right second premolar, after extraction. The two single-headed arrows point to the CEJ, which is the line separating the crown (in this case, heavily decayed) and the roots. The double headed arrow (bottom right) shows the extent of the abscess that surrounds the apex of the palatal root.
