Pericoronitis
Pronunciation: peh-ree-kor-oh-NY-tis
Inflammation of the soft tissue surrounding the crown of a partially erupted tooth, most often a mandibular third molar.
Full Definition
Pericoronitis is a localized inflammatory condition affecting the operculum—the flap of gingival tissue overlying a partially erupted tooth. It is most frequently associated with mandibular third molars and can present in acute or chronic forms. Acute pericoronitis may involve pain, swelling, trismus, and purulent discharge, while the chronic form is characterized by mild recurring discomfort. In clinical documentation, editors must preserve the distinction between 'pericoronitis' (soft tissue inflammation) and 'pericoronal abscess' (suppurative infection). The term is spelled with 'peri-' (around) and 'corona' (crown) and should not be hyphenated.
Usage
Usage note: Do not hyphenate. Distinguish from 'pericoronal abscess,' which denotes a discrete collection of pus rather than general inflammation.
