Odontogenic cyst

Odontogenic cysts are a group of jaw cysts that are formed from tissues involved in tooth development. They are a common form of cyst that can occur in the jaw, and they are categorized into two main types: developmental and inflammatory.

Developmental Odontogenic Cysts

Developmental odontogenic cysts are formed during the process of tooth development. They include several types of cysts such as:

• Dentigerous cyst: This is the most common type of developmental odontogenic cyst. It is associated with the crown of an unerupted or developing tooth.

• Keratocystic odontogenic tumour: Previously known as odontogenic keratocyst, this type of cyst is characterized by its aggressive behavior and high recurrence rate.

• Orthokeratinized odontogenic cyst: This is a rare type of odontogenic cyst that is less aggressive than the keratocystic odontogenic tumour.

Inflammatory Odontogenic Cysts

Inflammatory odontogenic cysts are formed as a result of inflammation. They include:

• Radicular cyst: Also known as periapical cyst, this is the most common type of inflammatory odontogenic cyst. It is usually associated with a non-vital tooth.

• Residual cyst: This type of cyst remains after the removal of the associated tooth.

Diagnosis and Treatment

The diagnosis of odontogenic cysts is usually made through a combination of clinical examination, radiographic examination, and histopathological examination. Treatment typically involves surgical removal of the cyst, although the exact approach may vary depending on the type and size of the cyst.
