title: Importance of differential diagnosis in endodontic-periodontal lesions: case reports.
abstract: Two case reports are presented in which the radiographic characteristics induced initially incorrect diagnoses. Only after combined clinical and radiographic examinations were the appropriate diagnoses achieved. This article demonstrates the need for close cooperation between periodontists and endodontists to diagnose periradicular lesions accurately.
