title: [Value of Gallium-67 scanning in differentiation of malignant and benign tumor in oral and maxillofacial area].
abstract: OBJECTIVE
  To evaluate Gallium-67 scanning in differentiation of malignant and benign tumor in oral and maxillofacial region.
  
  
  METHODS
  41 patients with tumors in the oral and maxillofacial region were undergone Gallium-67 scanning. The results were correlated with the final pathologic diagnosis.
  
  
  RESULTS
  Twenty out of 21 patients who had malignant tumors showed positive Gallium-67 scanning images (95.23%); three of 20 patients who had benign tumors also demonstrated positive results (15.00%). There was a significant difference between these two groups (P < 0.001).
  
  
  CONCLUSIONS
  Gallium-67 scanning is a useful adjunct tool for differentiation of malignant and benign tumors in oral and maxillofacial region.
