ABSTRACT
The periodontal status of a patient can be visualised on a chart built up from information taken from all the diseased areas. This involves recording all the dental anomalies and the depth of any pockets around each tooth, and transferring this information onto the chart. The extent of the periodontal destruction can then be assessed for future treatment planning. Pocket depths and areas of recession are measured using a standard measuring probe. Together with radiographic (X-ray) evidence a complex map relating to the periodontal status of the patient can be constructed. (See Figure 14 on page 31.)
A periodontal charting system called CPITN (Community Periodontal Index of Treatment Needs), has been developed for use when carrying out epidemiological surveys. It is quick to undertake and therefore large populations can be assessed. Information is obtained which provides some idea of the patients periodontal status at the time of examination.
