Plaque Control Record

- The Plaque Control Record -
(O' Leary T, Drake R, Naylor, 1972)


Guest editor: Kaban Moslehzadeh

The Plaque Control Record was developed to give the therapist, hygienist, or dental educator a simple method of recording the presence of the plaque on individual tooth surfaces. These surfaces are:

  • Mesial
  • Distal
  • Buccal
  • Lingual
  • At the control appointment a suitable disclosing solution such as Bismarck Brown, Diaplac or similar is painted on all exposed tooth surfaces. After the patient has rinsed, the operator (using an explorer or a tip of a probe) examines each stained surface for soft accumulations at the dentogingival junction. When found, they are recorded by making a dash/red colour in the appropriate spaces on the record form. Those surfaces, which do not have soft accumulations at the dentogingival junction, are not recorded.

    After all teeth are examined and scored, the index is calculated by dividing the number of plaque containing surfaces by the total number of available surfaces.



    CALCULATION EXAMPLE:

    Assume a patient with the following plaque accumulation:

  •   Upper jaw: 34 plaque containing surfaces
  •   Lower jaw: 36 plaque containing surfaces


    The total available surfaces for upper and lower jaw were, in this example, 52 and 48 receptively.

    Plaque Index = (The number of plaque containing surfaces) / (The total number of available surfaces)
    (34 + 36) / (52 + 48) = 70 / 100 = 0.70

    Meaning the plaque index for this patient is 70% at initial control appointment.
