Summary
Elevated subgingival temperature, especially above 35.5°C, indicates a higher risk for periodontal attachment loss. This finding is crucial for identifying individuals at greater risk of progressive periodontal disease.
Area of Science:
- Periodontology
- Biomedical Engineering
- Clinical Diagnostics
Background:
- Periodontal attachment loss is a key indicator of periodontal disease progression.
- Subgingival temperature has been explored as a potential diagnostic marker.
Purpose of the Study:
- To investigate subgingival temperature as a risk indicator for periodontal attachment loss.
- To assess the relationship between elevated subgingival temperature and the progression of periodontal disease.
Main Methods:
- Measured clinical parameters and subgingival temperature in 29 subjects at 6 sites per tooth.
- Used a periodontal temperature probe (Periotemp) and computed temperature differences between subgingival and sublingual sites.
- Analyzed 49 subject visits with baseline temperature and subsequent attachment level measurements.
Main Results:
- Attachment level loss >2.5 mm occurred in 16 of 49 subject visits.
- Elevated mean subgingival temperature (>35.5°C) significantly increased the odds of new attachment loss (OR 14.5 for ≥1 site, OR 64.0 for ≥2 sites).
- Discriminant analysis predicted disease activity with 82% overall agreement using clinical signs and temperature.
Conclusions:
- High mean subgingival temperature is a significant risk indicator for periodontal attachment loss.
- Subjects with high temperatures and widespread periodontal destruction face the greatest risk.
- Subgingival temperature measurement offers a valuable tool for predicting periodontal disease progression.
