Follicular Odontogenic Keratocyst Mimicking Dentigerous Cyst-report of Two Cases

Odontogenic keratocyst (OKC) is one of the most aggressive odontogenic cysts owing to its relatively high recurrence rate and its tendency to invade adjacent tissue. Radiographically odontogenic keratocyst can be of different types – follicular, envelopmental, replacemental, extraneous and collateral.The biological behaviour, prognosis, recurrence and therapeutic approaches vary in different studies. Further research is necessary in order to establish relationship between markers of proliferation and aggressiveness with regard to the radiographic varieties in OKC. The present article reports 2 cases of follicular odontogenic keratocyst that was submitted to our department with the provisional diagnosis of dentigerous cyst. AOSR 2011;1(2):100-103.
