اسلاید 3: INTRODUCTIONRadiolucent shadows cast partially over the periapical regions of the tooth in practically all oral radiographic survey of dentulous patients.The radiolucent shadows are:Anatomic pathologic

اسلاید 4: ANATOMIC RADIOLUCENCIES Unilocular: mental foramen Multilocular: maxillary sinus ,bone marrow spacesPATHOLOGIC RADIOLUCENCIES(Pulp and Periapical Radiolucencies): Inflammation in pulp;pulp necrosisperiapical granuloma, periapical abscess,periapical cyst, actinomycosis,sinus mucosal hyperplasia,Osteomyelitis.

اسلاید 5: BENIGN; traumatic bone cyst nasopalatine duct cyst adenomatoid odontogenic tumor periapical cemento osseous dysplasia vascular malformations like central haemangioma ossyfying fibroma

اسلاید 6: BENIGN AGGRESSIVE: odontogenic keratocyst central gaint cell granuloma odontogenic myxoma calcifying epithelial odontogenic tumor ameloblastoma MALIGNANT: metastatic

اسلاید 7: TRUE PERIAPICAL RADIOLUCENCIES; represent lesions that truly contacting apex of the tooth, their shadow cannot be changed by taking additional radiographs at different angles FALSE PERIAPICAL RADIOLUCENCIES; produced by anatomic cavities or lytic lesions that do not contacting apex of tooth;shadows may shifted by taking additional radiographs at different angle
