    Area of Science:

    • Dentistry
    • Endodontics
    • Medical Education

    Background:

    • Verbal mediators and mnemonics are effective memory aids in various fields.
    • Differential diagnosis of endodontic failures requires a systematic approach.

    Purpose of the Study:

    • To introduce a mnemonic device, POOR PAST, for recalling differential diagnoses of endodontic failures.
    • To simplify the diagnostic process for endodontic treatment.

    Main Methods:

    • The POOR PAST mnemonic lists potential causes: Perforation, Obturation, Overfill, Root canal missed, Periodontal disease, Another tooth, Split, Trauma.
    • Utilizing targeted questions, clinical examination, and diagnostic tests (pulp tests, radiographs, probing).
    • Evaluating factors like access preparations, occlusion, and etiologic factors.

    Main Results:

    • The mnemonic provides a comprehensive list, simplifying the recall of diagnostic possibilities.
    • Systematic questioning and specific tests help narrow down the differential diagnoses.
    • The mnemonic aids in identifying cases requiring further consultation or surgical intervention.

    Conclusions:

    • The POOR PAST mnemonic is a valuable tool for dentists in diagnosing endodontic failures.
    • Effective differential diagnosis leads to more accurate treatment planning and improved patient outcomes.
    • When all mnemonic possibilities are ruled out, it indicates complex cases requiring advanced care.
