Abstract:

Objectives: The most common pathologic processes of jaws with inflammatory origin from necrotic dental pulp are periapical lesions. Periradicular granuloma and radicular cyst are the most important lesions, which can be seen in the teeth with necrotic pulp or improper root canal therapy Various clinical methods have been used in attempts to differentiate a periradicular granuloma from a periradicular cyst. The only accurate way to distinguish these two entitles is by histologic examination. This study presents a clinical case of an extensive periapical lesion of endodontic origin, suggestive of peripheral radicular cyst of tooth #46.
Methods: The endodontic treatment was performed on tooth #46, the dressing with calcium hydroxide paste was renewed on a two-week basis for 2 months, followed by endodontic obturation of the root canal system.
Results: After one year of conventional endodontic treatment the patient is without any signs of recurrence
