Odontogenic keratocyst has been reported by many authors as a specific entity of odontogenic cysts since first described by Philipsen.<BR>Histopathologically, keratinization of the epithelial lining and formation of micro cyst; clinically, higher incidence of recurrence are characterized. Three hundred and sixty odontogenic cysts operated in the Department of Oral Surgery from 1966 to 1984 were studied. A representative histopathologic section from each cyst was screened, using the criteria for odontogenic keratocysts as stated by Pindborg.<BR>Of the 360 cases, 24 fullfilled the histologic criteria for odontogenic keratocysts, for a 6.7 per cent incidence. Of the twenty-four patients, one was diagnosed as basal-cell nervous syndrome, and had five cysts. Of the 24 patients, six had cyst recurrence for a rate of 32 per cent. One patient each had recurrence after one year five months, after three years, after three years four months, after three years five months, after four years six months and one four years ten months after the primary operation. Recently, some investigators have pointed out that odontogenic keratocyst may be benign cystic epithelial neoplasia. In our study, this opinion has been taken into account in view of the higher incidence of recurrence, but no histologically precise feature was obtained.
