ABSTRACT The squamous odontogenic tumor (SOT) is a rare, benign, locally infiltrative neoplasm of the jaws that appears to originate from the rests of Malassez, gingival surface epithelium or from remnants of the dental lamina. SOT was first described by Pullon et al. (1975). Since then there has been paucity in the number of reported cases, especially in the Indian subcontinent. The tumor is often asymptomatic, although it can present with symptoms of pain and tooth mobility. The characteristic radiographic appearance is that of a triangular-shaped unilocular radiolucency associated with the roots of erupted, vital teeth and has a predilection for the anterior maxilla and the posterior mandible. Histologically, the tumor is characterized by the formation of variably sized nests and cords of uniform, benign-appearing, squamous epithelium with occasional vacuolization and keratinization. We report a case of SOT occurring in a 58-year-old male in the anterior mandible with unusual localization and appearance.

    ABSTRACT: The purpose of this review was to describe the function of epithelial rests of Malassez (ERMs) in a variety of physiologic and pathologic conditions. The authors performed a PubMed search on the term "epithelial rests" alone or in combination with "Malassez." Relevant articles were categorized into primary subtopics and related to current and historic literature. The review was divided into 7 subtopics. Those sections discuss possible roles for ERM in a variety of physiologic and pathologic processes. ERMs have a fundamental role in root development, protect against root resorption, and are involved in reparative and regenerative functions of the pulp and periodontal tissues including apexogenesis and periodontal healing. They also appear to be involved in pathologic processes such as the development of oral cysts and tumors.

    ABSTRACT: Squamous odontogenic tumor is a rare benign neoplasm and may affect multiple sites in the mouth. SOT was first described by Pullon et al. (1975). Since then, there have been less than 50 reported cases. The tumor is often asymptomatic, although it can present with symptoms of pain and tooth mobility. We report a case of SOT occurring in a 26-year-old female in the anterior mandible with unusual localization and appearance.
