Wissenswertes über "Gingiva index"
The Gingiva Index (GI) is an established dental procedure for assessing the degree of inflammation of the gums (gingiva).
The Gingiva Index was introduced in 1963 by Löe and Silness and is used for the objective assessment of gingivitisi.e. inflammation of the gums, by assessing clinical characteristics such as redness, swelling, bleeding and surface structure. The Gingiva Index is used in daily practice and in clinical studies to document the health of the gums and measure the success of treatment.
The assessment is performed visually and by probing four surfaces of each tooth (mesial, distal, vestibular, oral) and is graded according to a numerical system from 0 to 3:
- 0 = healthy gums (pale pink, firm, no bleeding)
- 1 = mild inflammation(redness, slight oedema, no bleeding on probing)
- 2 = moderate inflammation (redness, swelling, bleeding on probing)
- 3 = severe inflammation(marked redness, oedema, spontaneous bleeding, possibly ulceration)
- Assessment of gingivitis based on visible characteristics
- Scale from 0 (healthy) to 3 (severe inflammation)
- detection on four tooth surfaces per tooth
- Application in clinical diagnostics and studies
- Supports the assessment and prevention of periodontal diseases
