Asymptomatic Apical Periodontitis
Inflammation and destruction of apical periodontium of pulpal origin that presents with no clinical symptoms but shows radiographic evidence of periapical bone loss.
Full Definition
Asymptomatic apical periodontitis (AAP) represents a low-grade chronic inflammatory response at the root apex, typically manifesting as a radiolucency on periapical or CBCT imaging in the complete absence of symptoms. It commonly develops from pulp necrosis or as a sequela of failed root canal treatment. Because it is painless, it is often detected incidentally during routine radiographic examination. Editors working on clinical audit reports or case series must distinguish it carefully from symptomatic apical periodontitis and from periapical granuloma, which is a histological—not a clinical—diagnosis. The full qualifier 'asymptomatic' is mandatory for diagnostic precision.
Usage
Usage note: The qualifier 'asymptomatic' must not be dropped. Distinguish from the histopathological diagnosis 'periapical granuloma', which requires tissue analysis.
