|III (Moderate Chronic Periodontitis)✝||5-6||Yes||33||I and II||1 and 2||3-4||Yes (localized or generalized)*|
|IV (Severe Chronic Periodontitis)✝||≥ 6||Yes||> 33||I, II, or III||1, 2, 3, or 4||≥ 5||Yes (localized or generalized)*|

The above classifications are from the American Dental Association/American Academy of Periodontology 1999. The below guidelines have been recently developed to improve the determination of classifications of periodontal disease. A new set of guidelines is scheduled to be released in 2017.
|Slight (Mild)||Moderate||Severe (Advanced)|
|Probing depths||> 3 & < 5mm||≥ 5 & < 7mm||≥ 7mm|
|Bleeding on probing||Yes||Yes||Yes|
|Radiographic bone loss||Up to 15% of root length or ≥ 2mm & ≤ 3mm||16% to 30% or > 3mm & ≤ 5mm||> 30% or > 5mm|
|Clinical attachment loss||1 to 2mm||3 to 4mm||≥ 5mm|
Upon performing the periodontal screening on Emmett, Jessica found that his periodontal pocket depths had increased from 2-3 mm to greater than 5 mm in most areas. Jessica completes her scaling and polishing of Emmett’s teeth and updates a plan for his oral health instructions that she will deliver to him after Dr. Jay does her clinical examination.
Dr. Jay to Mr. Davis: "Emmett, I can see from the data Jessica collected, that your periodontal pockets have increased significantly, and in looking at your radiographs, you have some bone loss. This is the reason that some of your teeth are loose and your gums are bleeding and tender. Unfortunately, your condition has progressed from gingivitis to periodontal disease (periodontitis). Have you experienced any bad breath?"
Mr. Davis to Dr. Jay: "Well, yes I have. I just thought it might be something I was eating."
Dr. Jay to Mr. Davis: "Actually, bad breath can also be a sign of periodontal disease."
