An orthokeratinized odontogenic cyst (OOC)
is a rare dental cyst, which has recently been separated from
the odontogenic keratocyst (OKC) in the WHO classification.
OOC has previously been described as a variant of OKC and
there has not been any consensus so far to distinguish between
follow-up of patients with OOC and OKC despite having
different prognosis.
CASE STUDY – A 17-year-old man had symptoms from a third
molar in the lower jaw. This, as well as an incidentally discovered
cyst relating to the tooth, was removed during surgery.
Pathological examination showed OOC.
CONCLUSION – It is important to distinguish between OKC and
OOC as OOC is less locally destructive and has significantly
lower recurrence rate. At present, no distinction is generally
made between follow-up for OKC and OOC, and patients
therefore often receive the same comprehensive follow-up.
However, it would be more efficient for patients with OOC to
undergo fewer follow-ups for a shorter period.
