Missing a vertical root fracture diagnosis
What it is
Failing to recognize a vertical root fracture — most often in an endodontically treated tooth — and instead diagnosing/treating it as: • persistent apical periodontitis (failed RCT) • a primary periodontal lesion • or a generic "endo-perio" problem AAE notes VRFs are a major diagnostic challenge and often present with characteristic patterns rather than a clearly visible fracture line on routine radiographs.
Why it happens
• Fracture line is rarely directly visible on 2D radiographs; the clue is usually the pattern of bone loss/PDL widening, not the line itself • Signs mimic endo-perio disease (sinus tract, swelling, deep pocket, isolated bone loss) • Over-reliance on "J-shaped/halo" radiolucency: it can occur in VRF, but it is not diagnostic by itself — so clinicians can both overcall and undercall VRF • No systematic probing: the key clue — deep, narrow, isolated probing defect — gets missed if probing is incomplete or superficial
