The evaluation of the periotron.

J J Garnick, R Pearson, D Harrell

    Journal of Periodontology
    |August 1, 1979
    PubMed
    Summary

    The Periotron device shows promise for detecting gingival inflammation in periodontal pockets. Its fluid volume measurements correlate with inflammation severity, but individual variations require calibration for accurate clinical use.

    Area of Science:

    • Periodontology
    • Biomedical Engineering

    Background:

    • Gingival inflammation is a key indicator of periodontal disease.
    • Accurate measurement of gingival crevicular fluid (GCF) is crucial for assessing periodontal health.
    • Existing methods for GCF assessment may have limitations in clinical settings.

    Purpose of the Study:

    • To evaluate the potential of the Periotron device for assessing gingival inflammation.
    • To determine the correlation between Periotron readings and established measures of gingival inflammation.
    • To identify factors influencing the accuracy of Periotron measurements.

    Main Methods:

    • Preliminary investigations using the Periotron device.
    • Comparison of Periotron data with known fluid volumes.
    • Correlation analysis with Gingival Index (GI) scores.
    • Assessment of Periotron variability and influence of fluid dissipation constants.

    Main Results:

    • The Periotron demonstrated potential utility in assessing gingival inflammation in periodontal pockets.
    • Successive recordings showed variability between 5-11%.
    • Periotron data exhibited a high correlation with increased fluid volumes and GI scores.
    • Measurements were influenced by the dissipation constant of gingival fluid.

    Conclusions:

    • The Periotron may be a useful tool for the clinical assessment of gingival inflammation.
    • Individual variations in the dissipation constant of gingival fluid necessitate evaluation for accurate clinical and research application.
    • Further studies are warranted to validate the Periotron's efficacy.
