Elevated temperature in periodontal pockets can indicate gum disease. A specialized probe found diseased teeth were significantly hotter than healthy ones, suggesting temperature is a diagnostic tool for periodontal inflammation.

Area of Science:

  • Periodontology
  • Biomedical Engineering
  • Diagnostic Medicine

Background:

  • Inflammation, a hallmark of periodontal disease, is often associated with elevated local tissue temperatures.
  • Assessing local temperature variations could offer a novel diagnostic approach for periodontal health.
  • Existing diagnostic tools for periodontal disease may not fully capture inflammatory activity.

Purpose of the Study:

  • To evaluate the potential of localized temperature measurement as a diagnostic indicator for periodontal disease.
  • To develop and validate a specialized temperature probe for periodontal site assessment.
  • To compare periodontal site temperatures between healthy subjects and those with advanced adult periodontitis.

Main Methods:

  • A novel, high-accuracy temperature probe with rapid response and good thermal isolation was designed.

  • Site temperatures were measured and normalized against sublingual temperature to account for core body variations.
  • A cross-sectional study compared pocket temperatures in 14 periodontitis patients and 11 healthy controls.

    • Main Results:

    • Mean site temperature in subjects with periodontitis was 0.65°C higher than in healthy subjects.
    • A posterior-to-anterior temperature gradient was observed, with posterior sites being warmer.
    • Diseased teeth exhibited significantly higher temperatures than anatomically equivalent healthy teeth (p < 0.01).

    Conclusions:

    • Localized site temperature is a sensitive indicator of inflammatory activity in periodontal disease.
    • The developed temperature probe effectively detected significant disease-related temperature elevations.
    • Temperature measurement shows promise as a supplementary diagnostic tool for periodontal disease assessment.
