Mandibular adenomatoid odontogenic tumor: Radiographic and pathologic correlation

It presents as a symptom-free lesion and is frequently discovered during routine radiographic examination.

Variable amounts of calcified materials were found in most AOTs Clinically, these lesions cannot be differentiated from the common gingival fibrous lesion [ 34 ]. Histological typing of odontogenic tumors, jaw cysts, and allied lesions. Effiom OA, Odukoya O. Epithelial-mesenchymal signaling during tooth development. Stern, Oral and Maxillofacial Pathology: Treatment can involve enucleation.


Most lesions are pericoronal, juxta coronal, and divergence of roots and displacement of teeth often occurs without root resorption. Summary and Conclusion Even though enucleation and curettage for AOT is the most common treatment modality, accurate histological diagnosis is mandatory to avoid unnecessary mutilating surgery.
