Periapical cemental dysplasia is generally regarded as a disease that develops at the apical region of vital teeth as a result of proliferation of the connective tissue of the periodontal membrane, and uncommon benign odontogenic tumors of mesenchymal origin. The new histologic classification of "Cementoma" includes periapical dysplasia, cementifying fibroma, benign cementoblastoma and giantiform cementoma (familial multiple cementoma). Periapical cemental dysplasia is rare.<BR>Moost common incidence is in middle age women, usually in the periapical regions of vital mandibular incisors. Occurence in the maxilla is very rare. The Patient complained of intermittent pain and swelling in the left buccal (maxillary sinus) region for 2 weeks, with concomitant maxillary sinusitis.<BR>We report a case of multiple periapical cemental dysplasia occurring in the maxilla and mandible. The appearance on radiography, of the premolar region and the presence of premolar lesions in the maxilla suggest diagnosis of florid osseous dysplasia (FOD).
