A periapical radiolucency around the apex on a radiograph may indicate which conditions?

• A. Abscess, granuloma, or cyst
• B. Healthy pulp
• C. Normal pulp vitality
• D. External resorption

Answer: (A)

A periapical radiolucency around the apex on a radiograph typically signals inflammatory or infectious changes in the periapical tissues due to pulpal disease. The most common possibilities are an abscess, a granuloma, or a cyst, all arising from necrotic or chronically inflamed pulp and causing bone loss at the tip of the root. An abscess is an acute or pus-filled lesion at the apex; a granuloma is a chronic inflammatory mass; a cyst is a fluid-filled sac that can form from inflammatory tissue around the root. This finding does not indicate a healthy pulp or normal vitality, which would not produce such a radiolucent lesion. External resorption is a different process that affects the root surface rather than presenting primarily as a periapical radiolucency.
