title: Clinical-statistic survey regarding odontogenic keratocysts in a sample of population in Eastern Sicily.
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.
