    probe all 4 areas of tooth and wait 30 seconds btw areas
  18. what is the coding for the SBI?
    • 0-5 for each of the 4 areas
    • total scores and divide by 4
    • total scores for each tooth and divide by number of teeth
  19. what index is the presence or absence of gingival inflammation by bleeding from the INTERPROXIMAL SULCI?
    gingvial bleeding index GBI
  20. where is the GBI measured?
    two interprox sulci per tooth
