Not using CBCT when 2D imaging is insufficient for the question
What it is
Sticking with periapical/bitewing (2D) radiographs even when they cannot answer the clinical question, leading to missed anatomy, missed pathology, or wrong treatment planning — despite clear indications where limited field-of-view (FOV) CBCT is recommended/considered. AAE/AAOMR position statements are clear: CBCT is not routine, but it should be used when the diagnostic need cannot be met by lower-dose 2D radiography and when benefits outweigh risks.
Why it happens
• Fear of radiation / cost → clinician avoids CBCT even when justified (ALARA/justification misunderstood) • Underestimating 2D limitations (superimposition; lesions/structures hidden; single projection ambiguity) • No "case selection" rule in the workflow (so CBCT is never triggered when 2D is inconclusive) • Overconfidence in 2D for complex endodontic questions (MB2, resorption type/extent, surgical planning, VRF suspicion)
