You have probably heard your dentist calling out numbers during your dental checkup and wondered what those numbers mean. Those numbers are part of a periodontal screening and recording (PSR). A PSR is a diagnostic rapid screening for periodontal disease. The dentist will use an instrument called a periodontal probe to examine the gum tissue around each tooth to ensure that there are no deep pockets or bleeding.
There are generally six numbers recorded for a PSR, as the mouth is divided into sextants. A zero represents no bleeding, no calculus, and probing depths less than 3.5mm. A one represents bleeding, but no calculus, and probing depths less than 3.5mm. Two signifies that there is bleeding and/or calculus, and probing depths less than 3.5mm. A record of three or four suggests that there are deep periodontal pockets greater than 3.5mm. The worst/deepest pocket in the sextant is recorded.
A complete periodontal examination is warranted when a score of three or more is recorded in two or more sextants. A complete periodontal examination is an in-depth evaluation of the bone and gums around your teeth which include a series of X-rays, a full “charting” of certain parameters and observations of your individual periodontal status in order to formulate a treatment plan to best serve your individual needs.
