PERIODONTAL 
              DISEASE DIAGNOSIS
            Periodontal disease is 
              diagnosed by your dentist or dental hygienist during a periodontal 
              examination. This type of exam should always be part of your regular 
              dental check-up.
            A periodontal probe (small 
              dental instrument) is gently used to measure the sulcus (pocket 
              or space) between the tooth and the gums. The depth of a healthy 
              sulcus measures three millimeters or less and does not bleed. The 
              periodontal probe helps indicate if pockets are deeper than three 
              millimeters. As periodontal disease progresses, the pockets usually 
              get deeper.
            Your dentist or hygienist 
              will use pocket depths, amount of bleeding, inflammation, tooth 
              mobility, etc., to make a diagnosis that will fall into a category 
              below:
            Gingivitis
            Gingivitis is the first 
              stage of periodontal disease. Plaque and its toxin by-products irritate 
              the gums, making them tender, inflamed, and likely to bleed.
            Periodontitis
            Plaque hardens into calculus 
              (tartar). As calculus and plaque continue to build up, the gums 
              begin to recede from the teeth. Deeper pockets form between the 
              gums and teeth and become filled with bacteria and pus. The gums 
              become very irritated, inflamed, and bleed easily.Slight to moderate 
              bone loss may be present.
            Advanced Periodontitis
            The teeth lose more support 
              as the gums, bone, and periodontal ligament continue to be destroyed. 
              Unless treated, the affected teeth will become very loose and may 
              be lost. Generalized moderate to severe bone loss may be present.
