Misreading radiographs (perceptual miss of a visible lesion)
What it is
A perceptual miss is when an abnormality is actually visible on the radiograph in retrospect, but the clinician fails to see it during interpretation (e.g., early periapical radiolucency, missed recurrent caries, missed root fracture sign, missed resorption). This is different from a "knowledge" problem (seeing it but misinterpreting it).
Why it happens
• No systematic search pattern → the eyes jump to the obvious area and skip "quiet" zones • Satisfaction of Search (SOS): once you find one issue (e.g., a large caries), you unconsciously stop looking for additional findings (e.g., secondary caries, periapical change, missed canal) • Time pressure / cognitive load (busy clinic, emergency pain) → faster scanning = more misses • Suboptimal image quality/geometry (positioning, overlap, exposure) makes subtle findings easier to miss; repeat/retake and QA matter • 2D limitations (anatomical superimposition; lesion may not be obvious depending on angulation) → "normal-looking" film can still hide disease
