Bluish swelling that occurs on the soft tissue over an erupting tooth
An eruption cyst, or eruption hematoma, is a bluish
swelling that occurs on the soft tissue over an erupting
tooth. It is usually found in children. The fluid in the
cyst is sometimes clear creating a pale-coloured cyst although often they are blue. An eruption cyst (eruption
hematoma) is a developmental soft-tissue cyst of
odontogenic origin that forms over an erupting
tooth. most commonly seen anterior to first molar
Clinical features
common in children while rare in other ages and found in both dentition
forms superficially in the
gingiva overlying the involved erupting tooth as soft, rounded and bluish swelling.
The fibrous capsule shows inflammatory cells possibly as a result of trauma.
The epithelial lining of the cyst is separated from the
alveolar mucosa by a thin layer of fibrous tissue with the epithelial tags of
cysticepithelium facing those of the alveolar mucosa.
The cystic cavity may contain blood in addition to the yellowish
protein fluid as a result of trauma.
Management
The cyst roof may be drained with its fluid to allow the tooth to erupt although most of them burst spontaneously.[1]
