What is computerised periodontal probing?
This is a painless and minimally invasive manoeuvre performed with a periodontal probe, a standardised, millimetre-scale instrument that is inserted between the tooth and the gum until reaching the bottom of the gingival furrow.

This exam reveals the following:

  • The depth of the pocket (pockets more than 4 mm deep are considered indicative of periodontal disease).
  • The millimetric measurement of the receding gums, that is, the distance between the gingival margin and the dividing line between the enamel and the cementum of the tooth.
  • The presence of sub-gingival tartar (if this is present, ridge-like object is felt by the probe).
  • The presence of pus and bleeding, which are the main signs of infection and inflammation.
  • The involvement of any furcations in the multi-rooted teeth.

Tooth mobility

The measurements are carried out on six points per tooth, by exerting a probing force equal to 20-30 grams to ensure tissues are left undamaged.

All these measurements are then recorded on a specific graph chart of the dental arches, so that the patient can also clearly see the health conditions of their mouth.

This probing is therefore fundamental to determining the progress of the periodontal disease and differentiate patients with gingivitis from those suffering from periodontitis.

In addition to helping the patient recognise any problems in the oral cavity, it is also important that the clinician identifies outbreaks of infection which require action to be  taken during treatment in order to prevent the spreading of the infection, and to judge the degree of effectiveness of the treatment over time.
