Pericoronitis
Pronunciation: peh-ree-kor-oh-NY-tis
Inflammation of the soft tissue surrounding the crown of a partially erupted tooth, most frequently a mandibular third molar.
Full Definition
Pericoronitis occurs when the operculum — the flap of gingival tissue overlying a partially erupted tooth — becomes inflamed due to bacterial accumulation in the underlying space. It is most common around mandibular third molars and can present as either acute (trismus, purulent exudate, systemic signs) or chronic (low-grade recurring discomfort). Editors should note that the term is one word and not hyphenated. It must not be confused with pericoronal abscess, which implies a more advanced, localised pus-filled lesion. The condition is relevant to dental hygiene documentation because hygienists may be among the first to identify it during routine assessment.
Usage
Usage note: Spell as one word: 'pericoronitis', not 'peri-coronitis'. Specify acute or chronic form where clinically documented.
