- Six observers with different amount of experience in the field of Oral and Maxillofacial Radiology interpreted the radiographs of 13 cases of ameloblastoma and 8 cases of odontogenic keratocyct which were confirmed histopathologically and showed pseudo-multilocular appearance and scalloped border radiographically. The authors examined the accuracy of radiologic diagnoses, interobserver agrement and intraobserver agreement. The obtained results were as follows; 1. The accuracy of radiologic diagnosis ranged from 0.48 to 0.81. The average value was 0.61. 2. The accuracy of radiologic diagnosis for ameloblastoma(0.55) was lower than that for odontogenic keratocyst(0.70) (P<0.05). 3. The overall agreement among the 6 observers was 14.3％ at the first interpretation and 19.0％ at the second interpretation. 4. The intraobserver agreement of each observer expressed in kappa index ranged from -0.14 to 0.64. The overall intraobserver agreement was 0.29. 5. The intraobserver agreement of each observer for ameloblastoma and odontogenic keratocyst ranged from -0.07 to 0.65 and from -0.25 to 1.00, respectively. The overall intraobserver agreement for ameloblatoma and odontogenic keratocyst were 0.27 and 0.26, respectively. 6. The diagnostic accuracy highly correlated to the intraobserver agreement(r=0.6370).
