Squamous cell carcinoma
- The most common oral malignant tumor.
- The jaws are affected by peripheral infiltration when the tumor is located in the gingiva, the alveolar mucosa, the floor of the mouth and the hard palate.
- The radiographic findings depend on the degree of infiltration. Computed tomography is necessary to accurately determine bone destruction.
- Radiograhically an ill defined, osteolytic radiolucency, is observed which initiates as peripheral bone erosion.
- The adjacent teeth are loosened (floating teeth) and the root is laterally resorbed giving the characteristic picture of 'nail end effect'.
