Findings

No curated finding names periapical periodontitis yet. Everything below is reference data from Mondo, HPO and GenCC, not evidence about what affects it.

Definition

Inflammation of the periapical tissue. It includes general, unspecified, or acute nonsuppurative inflammation. Chronic nonsuppurative inflammation is periapical granuloma. Suppurative inflammation is periapical abscess.
