Foundations
The primary etiologic factor in periodontal disease
Plaque biofilm
Staging is based primarily on severity and.....
complexity of management
Grading estimates the
Rate of disease progression
Normal probing depth in health
1-3 mm
Loss of attachment measured from this landmark
CEJ
Bone loss to the coronal 1/3 of the root
Stage I or II
Smoking more than 10 cigarettes a day results in
Grade C
Clinical attachment loss is calculated using
Inflammation limited to gingiva without attachment loss
Gingivitis
Bone loss extending to the middle third of the root
Stage III
Uncontrolled diabetes automatically increases
Grade
Bone loss that follows the contour of the CEJ's
Horizontal bone loss
Furcation involvement automatically places the patient at least in
Stage III, Furcation=complexity
Bone loss relative to age is used to determine
Grade
The defining feature that separates gingivitis from periodontist
Clinical attachment loss
Stage IV periodontist is defined by
Masticatory dysfunction and/or tooth loss due to periodontist
Grade B is characterized by
Moderate rate of progression
