Odontogenic tumors comprise a range of disorders of growth since benign and malignant tissue by dental malformations. Many markers of cellular differentiation during odontogenesis are abnormally expressed in benign odontogenic tumors, including matrix metalloproteinases and their inhibitors. This book may help you on the laboratory pathological diagnosis in benign odontogenic tumors, as Ameloblastoma and Calcifying Cystic Odontogenic Tumor through the expression of matrix metalloproteinases (MMPs), RECK , EMMPRIN/CD147 and their inhibitors (TIMPs).
