1. to avoid parallax error 2. to easily distinguish between shallow and deep pockets
to avoid confusion
The 4 and 6 markings on the William's probe were left out to avoid confusion. Without these two numbers, it is easier to determine the size of a pocket given that the numbers are extremely tiny.

A "perio probe" or "Periodontal Probe" to be exact, is a long thin ( blunt at the end) metallic instrument used by dentists, hygienists and orthodontists to explore inside the mouth. primarily used to check below the gum-line without damaging the gums.
Gingivitis is distinguished from periodontal disease (periodontitis) by the lack of periodontal attachment loss (PAL). PAL is determined by measuring the depth of the space between the tooth and gum (sulcus) with a dental probe, and by measuring the distance from the depth of the sulcus to the cemento-enamel junction, the point dividing the clinical crown from the root of the tooth. A probe depth of 3mm or less is typically considered to be normal. The deeper the depth, the more advanced the periodontitis. Gingivitis is simply inflamed gums with no loss of periodontal attachment. Once there is measurable loss of attachment, it is called periodontitis.
I think you are referring to the measurements on the 'periodontal Probe'...basically a milimeter ruler that the dentist uses to measure the 'pocket depth' of the gingival sulcas. you want 3 mm or lower.
"Because you already lost bone due to destructive bacteria. Scaling slows the progression of further damage." New AnswerI partly disagree with the answer above. Actually, probe depths should "decrease" when you go from a state of periodontitis to a stable periodontal condition (stable = no inflammation or infection). However, the periodontal destruction that has occured (know as CAL - Clinical Attachment Loss) does not change once the disease is arrested. You may get some clinical attachment "gain," but it is usually minimal without surgery. Your dental hygienist or periodontist will note the changes in perio probe depths before and after debridement of the endotoxins and calculus. You should see 1-3mm reduction after treatment. If the measurements don't decrease, then it may be an indicator that the pocket is not healing, or it was not inflammed previously. If it bleeds or is not light pink in color, then it is still inflammed and needs more attention. Periodontal Educator, Private College (BWD)
Firing order is 1-2-3-4-5-6. You migth be able to check cylinder numbers by looking at the distributor markings.
Probe,probe se 2.0 / probe gt 2.5
Space probe is a station.
I would think a Probe owners club is for owners of Ford Probe cars.
