Evaluation of Tenascin Expression in Ameloblastoma, Odontogenic Keratocyst, and Dentigerous Cyst by Immunohistochemistry.

Background: The aim of this study was to evaluate the expression pattern of tenascin in ameloblastoma, odontogenic keratocyst, and dentigerous cyst.

Materials And Methods: The expression of tenascin was evaluated in microscopic slides of 42 paraffin blocks including 12 ameloblastomas, 15 odontogenic keratocysts, and 15 dentigerous cysts by immunohistochemistry. The expression of tenascin was examined in stroma, epithelium-connective tissue interface, and epithelium of the lesions by two pathologists semiquantitatively.
