Gingival bleeding in an experimental clinical trial design.

T L Watts, M A Lennon, R M Davies

    Journal of Clinical Periodontology
    |February 1, 1979
    PubMed
    Summary

    This study evaluated gingival bleeding onset as an early gingivitis indicator. A chlorhexidine mouthrinse showed statistically significant effectiveness in reducing bleeding, validating this method for screening anti-gingivitis agents.

    Area of Science:

    • Dentistry
    • Periodontology
    • Clinical Trials

    Background:

    • Gingivitis is an early stage of periodontal disease characterized by gum inflammation.
    • Early detection of gingivitis is crucial for effective intervention and prevention of progression.
    • Assessing gingival bleeding is a potential non-invasive method for monitoring gingival health.

    Purpose of the Study:

    • To evaluate the onset of gingival bleeding as a reliable indicator of early gingivitis.
    • To assess the efficacy of chlorhexidine mouthrinse in preventing gingivitis using bleeding onset as a measure.
    • To determine the utility of this method in screening potential anti-gingivitis agents.

    Main Methods:

    • An experimental, double-blind, crossover clinical trial was conducted.
    • Twenty-nine dental students participated in the study.
    • Gingival bleeding onset was assessed using three different methods after intervention with chlorhexidine mouthrinse or placebo.

    Main Results:

    • One of the assessment methods demonstrated a statistically significant difference (P = 0.02) in favor of the active chlorhexidine mouthrinse.
    • This indicates that chlorhexidine was effective in inhibiting factors leading to gingival bleeding.
    • The results suggest the sensitivity of the chosen method in detecting early signs of gingivitis.

    Conclusions:

    • The onset of gingival bleeding can serve as a valid indicator for early gingivitis detection.
    • The experimental method used is effective in screening agents for anti-gingivitis properties.
    • This approach offers a promising tool for future clinical trials evaluating periodontal disease interventions.
