periapical pathology
Pronunciation: pair-ee-AP-ih-kal path-OL-oh-jee
Disease processes affecting the tissues surrounding the root apex of teeth, typically resulting from pulpal necrosis or trauma.
Full Definition
A broad category of conditions affecting the periradicular tissues, commonly encountered in oral and maxillofacial surgery. These lesions include periapical granulomas, radicular cysts, acute and chronic abscesses, and condensing osteitis. Most arise from bacterial invasion of necrotic pulp tissue, leading to inflammatory responses in the surrounding periodontal ligament and alveolar bone. Radiographic presentation varies from discrete radiolucencies to mixed radiolucent-radiopaque lesions. Surgical management may involve apicoectomy, retrograde filling, or complete tooth extraction depending on the extent of damage and treatment history.
Usage
Usage note: Umbrella term encompassing various inflammatory conditions around tooth roots.
