Pathologic fractures of the mandible following invasive oral carcinomas.

Invasive and metastatic oral carcinomas can and often do result in pathologic fractures of the facial bones. Three cases of invasive oral carcinomas resulting in fractures of the mandible have been reported. It was only after multiple-view radiographs that pathologic fractures could be identified. It is mandatory that dental practitioners avail themselves of the radiographic views which assist in establishing a diagnosis. In addition, the role of the dental profession in diagnosing primary and secondary oral carcinomas cannot be overemphasized.
