The operculum is a soft tissue covering the crown of a partially erupted tooth. This area is difficult to access, and hence the normal oral hygiene methods remain ineffective, leading to inflammation of the soft tissue. This inflammation of the soft tissue surrounding the crown of a partially erupted tooth is called pericoronitis. It is known to appear when the third molars start to erupt, and are most commonly seen with the partially erupted/impacted mandibular third molars. Pericoronitis is treated by extraction of the third molar or by performing operculectomy. Operculectomy is a procedure which is done by excising the excessive soft tissue covering the third molar. It is indicated when there is availability of space for eruption of third molar, presence and proper alignment of antagonist tooth and impacted third molar in the arch.
