title: Calcifying odontogenic cyst: radiologic findings in 11 cases.
abstract: OBJECTIVE
  This retrospective study examines the relationship between histopathologically diagnosed cases of in calcifying odontogenic cysts (COCs) on the adjacent dentition.
  
  
  METHODS
  The records including diagnostic radiograph images of 11 patients treated for COCs from 1991 to 2004 were analyzed and correlations made between radiologic and histopathologic features. Special attention was applied to the associations between COCs and adjacent teeth.
  
  
  RESULTS
  Radiologic and histopathologic features of the 11 lesions were variable, with some lesions being more solid and others more cystic. Calcifications varied from small flecks to solid calcified areas of frank odontoma. In 7 cases, the COC was associated with an impacted tooth and 5 of these cases involved COC-enveloping teeth. All cases excepting one in an edentulous jaw segment showed positional changes of adjacent teeth, including impaction.
  
  
  CONCLUSIONS
  The radiographical features of COCs are varied but there is a high frequency of changes in adjacent teeth, including dental impaction. The presence of impaction or displacement of teeth for COCs occurring in the posterior segments of the jaw, and absence of this finding for anteriorly placed lesions may be indicative of the timing of COC development.
