ORTEGA, Ana Isabel. Squamous Odontogenic Tumour: Clinical, radiographic and histological aspects - Review of  the literature. Acta odontol. venez [online]. 2002, vol.40, n.3, pp.310-314. ISSN 0001-6365.

Squamous odontogenic tumour is a rare benign neoplasia that is probably originated from the cell rests of Malassez, in the periodontal ligament. Asymptomatic, in the majority of the cases, it can be associated with dental mobility and sensibility to percussion and palpation. It appears in equal frequency in maxilla and mandible. Radiographically, the most common image is a triangular or circular radiolucent area associated with the roots of involved teeth, being possible to present a multilocular image. The diferencial diagnosis can be a periodontal disease or injuries more aggressive like ameloblastoma and squamous cell carcinoma. Although to be a rare disease, the dentist must consider the TOE in the diagnostic hypotheses, to  establish a definitive diagnosis as soon as possible, and perform more conservatives intervetions, that will improve the patient’s prognostic. In order  to contribute to the best understanding of this entity and to alert the clinicians, in special the radiologists, of the existence of the TOE, this paper makes some considerations about the benign nature of this injury, its biological behavior and its histologics, clinical and radiographics aspects.
