  1. Oral Health Training & Calibration Programme Gingival Index

  2. Calibration Challenge • Probing by the first examiner increases likelihood of bleeding found by next examiner • Therefore the training will focus on the technique rather than actual score

  3. Principles • Sensing force - 20 grams • test this by placing the probe tip under the thumb nail and press until blanching occurs

  4. Gingival index: Index teeth • No substitutes except deciduous teeth for permanent (55 52 64 75 72 84) • Permanent teeth take precedence

  5. Gingival indexGingival Examination • Evaluate tissue changes in terms of: • Color coral pink vs. deep red • Consistency firm, resilient vs. edematous/fibrotic • Contour knife-edge margins vs. rolled margins Scalloped papilla vs. bulbous/thickened papilla

  6. Gingival index • No substitutes allowed • The index assesses the severity and prevalence of gingivitis by examining only the qualitative changes • Use the probe as a sensor (do not probe the pocket/sulcus depth) • Assess the mesial, distal, facial and lingual • Consider sensing all teeth in an arch then recording the score allows time for bleeding to occur

  7. Gingival Index – On All Ages • Dry lightly with cotton rolls • Use Williams probe • 20g pressure (blanch nail bed) • Do not probe around implants • Angle of probe tip to follow anatomical configuration of tooth – follow the long axis of the tooth

  8. Gingival Index (Loe & Silness 1963) • 0. Absence of inflammation • 1. Mild inflammation; slight change in colour and little change in texture. No bleeding on probing • 2. Moderate inflammation; moderate glazing, redness, oedema and hypertrophy; bleeding on sensing • 3. Severe inflammation; marked redness and oedema; tendency to spontaneous bleeding; ulceration • 4. Permanent and primary tooth missing

  9. Stages of Inflammation 0. Absence of inflammation 1. Mild inflammation; slight change in colour and little change in texture

  10. Stages of Inflammation 2. Moderate inflammation; moderate glazing, redness, oedema and hypertrophy; bleeding on pressure 3. Severe inflammation; marked redness and hypertrophy; tendency to spontaneous bleeding; ulceration
