What causes periapical pathology?
In contrast, the primary cause of periapical lesions is endodontic infection. PAMPs-triggered immune response induces proinflammatory cytokines and subsequent periapical pathosis, including chronic inflammation and bone destruction. The primary cause of periapical lesions does not overlap with metabolic disorders.

The index is based on a study by Brynolf [6] which correlated histological and radiographic findings.
Where is periapical?
A periapical (per-e-AP-ih-kul) abscess occurs at the tip of the root. A periodontal (per-e-o-DON-tul) abscess occurs in the gums at the side of a tooth root.
