Periodontal disease is broken up into four separate stages: gingivitis, slight periodontal disease, moderate periodontal disease, and advanced periodontal disease. Gingivitis. Gingivitis is the only stage of periodontal disease that is reversible as it has not yet had time to attack the bones.
The same is true for periodontitis. Step 1: “Initial Case Overview to Assess the Disease” – then using the findings from this assessment you determine the ‘stage’ of disease. Step 2: “Establish Stage” – divided into two sections “mild to moderate” and “moderate to severe”.
Advanced Periodontal Disease is characterized by more advanced bone loss around the teeth. There is 50% bone loss or more. Pockets typically measure 7-9mm or more, and there may or may not be tissue loss (recession of the gums) and mobility.
