Subgingival temperature measurements accurately assess periodontal inflammation. Actual subgingival temperature and temperature differential offer unique insights and may reduce clinical trial sample sizes and duration.

Area of Science:

  • Periodontology
  • Biomedical Engineering
  • Clinical Trials

Background:

  • Elevated temperature is a key sign of inflammation.
  • Subgingival temperature assessments offer reliable, quantitative data on periodontal inflammatory status.
  • Three forms exist: actual subgingival temperature, temperature differential, and an indicator light, posing interpretation challenges.

Purpose of the Study:

  • To determine if three subgingival temperature assessments differentiate between periodontal health and disease.
  • To identify whether these assessments are dependent or independent clinical variables.
  • To explore their potential for improving clinical trial efficiency.

Main Methods:

  • Comparison of three subgingival temperature assessment methods (actual temperature, temperature differential, indicator light) against clinical definitions of periodontal health and disease.

  • Correlation analysis with bleeding on probing.
  • Scatter-plot matrices and common factor analysis to assess variable independence.

    • Main Results:

    • All three methods successfully differentiated between periodontal health and disease (p<0.02).
    • All assessments showed significant, modest correlation with bleeding on probing (p<0.03, r>0.49).
    • Actual subgingival temperature and temperature differential were identified as independent variables.

    Conclusions:

    • Subgingival temperature and temperature differential provide unique, valuable information on periodontal inflammation.
    • The temperature differential shows potential to reduce sample size and trial duration in gingival inflammation studies.
    • Objective, quantitative temperature data can enhance the efficiency of periodontal clinical trials.
