Metrical differential diagnosis based on location (Part 2). Differential diagnosis among various benign tumors.
An attempt was made to quantify the location of various oral lesions using panoramic radiographs of benign tumors (20 ameloblastomas, 5 myxomas, 26 odontomas, 10 cementomas and 4 osteomas). The metrical data (integers) were obtained from a conversion table and the abscissa values (to the first decimal place) were obtained from the centroid of each of the tumors. Differential diagnosis among these lesions revealed that in the mandible, it is possible to differentiate between ameloblastomas and odontomas or osteomas. Thus, the present findings demonstrate that data on lesion location can be changed into metrical data for differential diagnosis of benign tumors.
