Indices

Indices turn findings into scores you can track. The O'Leary Plaque Control Record aims for 10% or less, OHI-S combines debris and calculus scores on six index surfaces, the Gingival Index grades inflammation from 0 to 3, and DMFT counts lifetime caries experience. Plaque and gingival indices are reversible, while DMF and attachment measures are irreversible.

  1. Plaque Control Record (O'Leary): percentage of surfaces with plaque, 4 surfaces per tooth; a goal of 10% or less.T2
  2. Patient Hygiene Performance (Podshadley and Haley): same 6 index teeth as OHI-S, each surface divided into 5 areas, score 0-5 per tooth.T2
  3. OHI-S index teeth: facial of #3, #8, #14, #24 and lingual of #19 and #30.T2
  4. Debris and calculus indices each score 0-3; OHI-S totals 0-6; 0-1.2 good, 1.3-3.0 fair, 3.1-6.0 poor.T2
  5. Gingival Index (Loe and Silness) averages 0-3: 0.1-1.0 mild, 1.1-2.0 moderate, 2.1-3.0 severe gingivitis.T2
  6. Eastman Interdental Bleeding Index uses a wooden interdental cleaner inserted 4 times; bleeding within 15 s counts.T2
  7. Dean's Fluorosis Index: normal, questionable, very mild, mild, moderate, severe; each person is scored by the two most affected teeth, and the community index is a weighted average of those scores.S34
  8. DMFT: decayed, missing and filled permanent teeth; DMFS counts surfaces. Lowercase dmft/deft are for primary teeth (e = indicated for extraction).T2
  9. Root Caries Index (Katz): root lesions divided by teeth with recession, times 100.T2
  10. An index should be valid, reliable, clear, simple, quantifiable, sensitive and acceptable.T2
  11. Gingival indices and plaque indices are reversible; DMF and CAL-based measures are irreversible.T2
