Oral Health Training Calibration Programme Gingival Index 1

Oral Health Training & Calibration Programme Gingival Index 1

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 2

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

Gingival index: Index teeth 7 6 543 2 1 7 6 5 4 321 12 3 1 4 567 23456 7 No substitutes except deciduous teeth for permanent (55 52 64 75 72 84) Permanent teeth take precedence 4

Gingival index Gingival 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 5

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 6

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

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 8

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

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 10
