Thermally induced pulpalgia, or tooth pain from heat, can occur in endodontically treated teeth. Treating previously unfilled canals resolved the pain in these two cases.

Area of Science:

  • Dentistry
  • Endodontics
  • Dental Pain Management

Background:

  • Endodontic treatment aims to remove infected pulp and prevent future infection.
  • Occasionally, endodontically treated teeth can develop persistent or new symptoms.
  • Thermally induced pulpalgia presents a diagnostic challenge in previously treated teeth.

Observation:

  • Two patients presented with severe tooth pain specifically triggered by heat.
  • Both teeth had a history of root canal therapy.
  • Reproducing the chief complaint was crucial for diagnosis.

Findings:

  • An unfilled canal was identified in each case.
  • Subsequent treatment of the missed canal led to complete resolution of symptoms.
  • This suggests incomplete root canal treatment as a cause of thermal pain.

Implications:

  • Missed canals in endodontically treated teeth can harbor pathology leading to pain.
  • Thorough endodontic evaluation and retreatment may be necessary for persistent pain.
  • Understanding the etiology of thermally induced pulpalgia is vital for successful treatment outcomes.
