Abstract
BACKGROUND: The aim of this study is to point out the frequency, histologically documented, of the odontogenic keratocysts in Eastern Sicily, through the study of a sample of 220 cystic neoformations. Of these, those presenting histopathological peculiarities of odontogenic keratocysts have been examined. METHODS: Fifteen keratocysts were histologically classified. The following characteristics were examined: histological character, age and sex, location of the lesion, association to unerupted teeth. RESULTS: Of the 220 cystic neoformations observed, at the histological examination, 15 were odontogenic keratocysts. The 53% were found in males, against the 47% in females. In the 67% of the cases the lesion involved lower-jaw, against the 33% of the jaw-bone. The greatest frequency was found in the angle of the mandible, followed by the frontal region of the jaw-bone, by the premolar/molar region of the mandible, by the lower frontal region and by the premolar/molar region of the jaw-bone. None odontogenic keratocysts relapsed following surgical operations. Patients are kept under observation and, to this point, elements of release have not emerged. CONCLUSIONS: The epidemiologic data found, are in line with those of the literature. We confirm the necessity of a precocious diagnosis for programming a correct surgical treatment and for reducing the risk of relapse and of ameloblastomatouses transformation.
