Abstract

Introduction: In the maxillofacial region, cysts and tumors relatively have high prevalence and during a current study of radiography, the dentists may incidentally encounter them. According to the wide usage of the conventional panoramic radiography in routine study of dentoalveolar structure and the availability and cheapness of this technique, it seems necessary to determine the accuracy of conventional radiography in diagnosis of benign and malignant lesions. Materials & Methods: In this descriptive study, all the cases with intraosseous lesions of maxillofacial region over a six-year period (2002-2008) from the archives of the radiography, surgery and oral health departments at Mashhad school of dentistry were collected. Then radiographic images were studied by one maxillofacial radiologist as an observer and according to the radiographic features, the state of being malignant or benign and then the type of lesions were diagnosed. Finally the findings of radiographic and histopathologic studies were compared using McNemar test. Results: From 136 intraosseous lesions, 116 lesions were benign and 20 lesions were malignant. From 20 malignant lesions, in 19 cases the radiographic and histopathologic diagnosis was the same and from the 116 benign lesions, 107 cases were diagnosed benign in radiography. A significant relationship was also detected among radiographic and histopathologic features (P=0.021). Conclusion: In this study diagnosis of conventional radiographies, in 92 of cases, with histopathologic results (benignity or malignancy of lesions) was adapted.
