Online published on 22 March, 2016. Abstract The odontogenic cyst is derived from rest of dental lamina which shows a different growth mechanism and biological behaviour from the more common dentigerous and radicular cyst. The pathogenesis of syndrome associated and sporadic keratocystic odontogenic tumour (KCOT) involve a ‘two hit mechanism ’with allelic loss, which shows that the odontogenic cyst is not a cyst but a tumour.
