Objective: To study the expression of matrix metalloproteinase(MMP) and tissue inhibitor of metalloproteinase (TIMP) in ameloblastoma (AB) and to determine the relationship between biological behavior of AB and clinical pathology.
Methods: The specimens of 43 cases of AB, 10 cases of odontogenic keratocyst (OKC), 8 cases of normal oral mucosa were examined by streptavidin-biotin method.
Results: In 8 cases of normal oral epithelial, MMP-2 was negative or weak positive.
