    Area of Science:

    • Biomedical Engineering
    • Dental Research
    • Imaging Analysis

    Background:

    • Accurate quantification of dental plaque is crucial for assessing oral hygiene and treatment efficacy.
    • Existing methods for plaque measurement can be subjective and time-consuming.
    • A need exists for objective, reproducible, and efficient plaque evaluation techniques.

    Purpose of the Study:

    • To develop and validate a planimetric, automatic method for evaluating dental plaque extension and volume.
    • To assess the reproducibility, discriminatory power, and time efficiency of the developed method.
    • To utilize the method for measuring in vivo plaque adhesion.

    Main Methods:

    • Acquisition of color macrophotographs of stained dental plaque.
    • Analysis of plaque images using a digitizer to input Cartesian coordinate data.
    • Calculation of plaque extension and volume using a calculator.
    • Estimation of method reproducibility, discriminatory power, and time requirements.
    • Interpretation of plaque adhesion ratios based on measurements before and after cleansing.

    Main Results:

    • The developed planimetric method demonstrated reproducibility and discriminatory power for plaque evaluation.
    • The automated approach significantly reduced the time required for plaque analysis compared to manual methods.
    • Measurements of plaque before and after cleansing provided a reliable assessment of plaque adhesion in vivo.

    Conclusions:

    • The automated planimetric method provides an objective and efficient tool for quantifying dental plaque.
    • This technique enhances the ability to assess plaque extension, volume, and adhesion.
    • The method holds potential for routine clinical and research applications in periodontology and oral hygiene studies.
