title: The frequency and distribution of idiopathic osteosclerosis of the jaw.
abstract: OBJECTIVE
  To determine the prevalence of idiopathic osteosclerosis (IO) in the jaw by radiographic evaluation and to investigate the relationship between the findings in relation to age, gender, and localization.
  
  
  METHODS
  The study included 2,211 panoramic radiographs obtained from the patients (915 men and 1,296 women) whose ages ranged from 10-77 and who visited the Department of Oral Diagnosis and Radiology in the Faculty of Dentistry, Erciyes University between 2008 and 2009.
  
  
  RESULTS
  Of 2,211 patients, 135 patients (6.1%) had IO. The prevalence obtained in our study was in the range reported in the literature. IO was detected more often in mandible rather than the maxilla. In addition, mandibular molar localization was the most common localization, and most of the lesions were associated with root apices.
  
  
  CONCLUSIONS
  In view of the findings, IO can be defined as developmental variations of normal bony architecture, which are unrelated to local stimuli. The lesions can arise at any age, any location with no sex predilection, and IO usually requires no treatment other than diagnosis. Because all these lesions were located in the jaw and could only is detected in panoramic evaluations, this indicates the importance of careful diagnostic evaluation of radiographies in dental examinations.
