    Study Notes

    Periodontal Health

    • Periodontal health can be evaluated through four aspects: bone loss, mobility, loss of attachment, and periodontal indices.
    • Periodontal indices are used to quantify and gather information about periodontal disease.

    Russell's Periodontal Index (RPI)

    • RPI is a popular index used to quantify periodontal disease.
    • It assigns a numeric score to each tooth, ranging from 0 (no inflammation or disease) to 8 (advanced destruction with loss of masticatory function).
    • The scores are averaged to obtain a Periodontal Index score.

    Gingival Index of Loe and Silness

    • This index is commonly used to evaluate gingival health.
    • It focuses on the loss of attachment as the sole indicator of periodontal health and disease.
    • The cervico-enamel junction (CEJ) is used as a reference point, and a special periodontal probe is used to take two measurements: the distance from CEJ to the free gingival margin (FGM) and from FGM to the base of the pocket.

    NIDR Gingival Index

    • This index is used to measure gingival bleeding.
    • The primary difference between GI and NIDR GI lies in the method of scoring.

    Properties of an Index

    • Validity: an index accurately reflects the extent or degree of a disease or condition.
    • Reliability: an index gives the same results with limited degrees of tolerance each time it is applied.

    Importance of an Index

    • An index is used to compare the oral health status of a population following intervention and treatment.

    Criteria for Selecting an Index

    • The index should address the specific information of interest.
    • The index should be suitable for the population.
    • The index should provide valid estimates of disease in the population.

    Reasons for Developing New Indices

    • To compare the oral health status of a population following intervention or treatment.
    • To accommodate population shifts and changes in disease experience.

    Dental Indices

    Caries Indices

    • DMF (Decay, Missing and Filled Index): provides a broad overview of caries activity in a population.
    • UTN (Unmet Restorative Needs): analyzes the needs of the population.
    • RCI (Root Caries Index): assesses the extent of root caries experience within the context of individual risk.

    Plaque and Oral Hygiene Indices

    • PHP (Personal Hygiene Performance Index): measures oral hygiene, plaque, and calculus, and can be used to document and motivate changes in oral health habits.
    • OHI-S (Oral Hygiene Index Simplified): a popular index for clinical epidemiologic research, quantifying plaque and calculus in two components: Debris Index and Calculus Index.

    Indices of Periodontal Health

    • Ways of looking at periodontal health include gingival health, mobility, loss of attachment, and periodontal indices.
