Differential diagnosis in endodontic failure

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.
