In most reported series, including those of Trodahl (1972) and Nilsen and Magnussen (1979), as well as individual case reports that we reviewed, ameloblastic fibromas were g associated with an impacted or unerupted tooth or teeth. The involved teeth usually are displaced. Although the displaced l teeth appear within the lesion, they are usually at the edge a of it, just inside the radiolucent area. When the tooth is exam- ined closely, there is no evidence of the lesion originating from or attaching at the cervical portion of the tooth, as would be seen in a dentigerous cyst. A right -angle view, r such as an occlusal radiograph, would show that there is no I hydraulic effect in the expanded cortex, as might be seen in a dentigerous cyst. Further, dentigerous cysts and amelo- blastomas have a great tendency to resorb the roots of erupted teeth in the region of the lesion. We found no men- tion of root resorption in association with ameloblastic fibroma. Although solitary lesions not associated with impacted or unerupted teeth do occur, their radiologic features have not been well described.
