title: [Analysis of clinical and imaging findings in cementoblastoma].
abstract: OBJECTIVE
  To assess the clinical and imaging features of cementoblastoma for diagnosis and differential diagnosis.
  
  
  METHODS
  Clinical and imaging data of 14 cases were selected for this retrospective study.
  
  
  RESULTS
  A total of 14 cases of cementoblastoma patients with ages at diagnosis ranging from 11 years to 58 years (mean age, 27.6 years; median age, 21.0 years). The tumor affected 7 patients from each gender. The mandible was the main site of occurrence. The most common complaints were swelling and pain. Radiographic results showed that cementoblastoma typically presented as a well-circumscribed and radiopaque mass confluent with the involved tooth root and surrounded by a thin and uniform radio-lucent border. Tumor parenchyma was generally mixed-density, which could be divided into two types, namely, homogeneous and heterogeneous patterns. Other significant imaging features included the periphery bone of the lesion sclerosis and cortical thickening of the lower edge of the mandible.
  
  
  CONCLUSIONS
  Obvious characteristics are found in the clinical and imaging findings of cementoblastoma. Accurate recognition of this lesion is significant in clinic to avoid misdiagnoses.
