In OKC which is more aggressive and has more recurrence potential
Orthokeratinized
Parakeratinized
Non keratinized
60% OKCs have Primordial origin (Dental lamina/cell rests of Serees). these are called primordial origin OKCs. They are Parakeratinized with thin friable lining and daughter/satellite cysts in their CT wall, hence great tendency to recur (1. multiplicative nature of primordial cells, thin lining that tears, 3. satellite cysts). rest of the 40% OKCs are Dentigerous origin OKCs (arise from Reduced enamel epithelium like dentigeous cysts). Since the proliferative potential of REE is lost, they dont have tendency to recur when their Orthokeratinized epithelial lining is left behind.
