title: [Idiopathic osteosclerosis in jaw bones. Clinical statistic study on a population of Sardinian origin].
abstract: BACKGROUND
  Idiopathic Osteosclerosis are localized, non-expansive and asymptomatic areas of bone radio-opacity, whose aetiology is unknown. The aim of this study was to assess its frequency, and distribution according to its location and to patients' age and gender, in a sample of patients native in Sardinia.
  
  
  METHODS
  697 consecutive clinical records of patients who underwent odontological treatment at the Department of Odontostomatologic Sciences at Cagliari University, over a 10-year period were studied. The panoramic radiographs attached to the clinical records were examined and searched for all cases that showed radio-opacity areas in maxillary bones that could be identified as idiopathic osteosclerosis (IO).
  
  
  RESULTS
  By examining orthopantomographies we have located 58 IOs. We found no significant differences between the sexes; average age was 37.8 years. The mandible has proved to be the most affected site (98.2%) in the first molar tooth region (34.5%), followed by the premolar teeth region (25.9%) and of the second molar tooth (15.5%). The lesions examined had an average diameter of 8.8 mm.
  
  
  CONCLUSIONS
  IO frequency has proved to be slightly higher than that reported in other articles, though remaining significantly lower than the values reported in Eastern populations. From the clinical point of view, IOs have been identified as sporadic radiographic findings without any real pathological relevance, except for one case in which the lesion caused nervous compression and dental retention, so that it was necessary to administer specific treatment.
