What is an Odontogenic Keratocyst (OKC)?
The odontogenic keratocyst (OKC) is the most important of
the tooth-derived cysts.
This cyst may have any clinical appearance; it is a great
mimic and the diagnosis is made after microscopic analysis.
This is the third most common tooth-derived cyst.
These cysts also are found as part of the Basal Cell Nevus
Syndrome, also known as Gorlin syndrome.
What are the causes of Odontogenic Keratocysts?
Their cause is controversial.
One theory is that the cyst develops instead of a tooth.
Presumably, the cells that would form the tooth undergo
cystic degeneration without ever completing tooth formation
and develop into the OKC.

The OKC has a number of 'compartments' and has
connecting smaller cysts that extend into the surrounding
bone. Because of this, there is frequent tendency for the
condition to recur, particularly if the original surgical
treatment did not result in complete removal of the cyst.
Removal of the cyst with removal of surrounding bone and /
or cryosurgery (intense cold is applied to the cyst and bone)
are the most common forms of treatment.
Long-term follow-up with monitoring by X-ray is important,
as if these cysts are left untreated, they can become quite
large and locally destructive.
