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
1-3mm
Gingivitis cause bone loss
False-Gingivitis is reversible
Loss of attachment measured from this landmark
CEJ
Bone loss to the coronal third of the root
Stage I or II
Smoking more 10 or cigarettes per day results in
Grade C
Clinical attachment loss is calculated using
Stage is determined be smoking status
Smoking affects Grade, NOT Stage
Inflammation limited to gingiva without attachment loss
Gingivits
Bone loss extending to the middle third of the root
Stage III
Uncontrolled diabetes automatically increases
Grade
Bleeding on probing indicates
Inflammation
Probing depth equals attachment loss
False
Bone loss that follows the contour of the CEJ
Horizontal Bone Loss
Furcation involvement automatically places the patient at least in
Stage III (furcation=complexity)
Bone loss relative to age is used to determined
Grade
Tooth mobility alone does NOT determine
Stage
Mobility automatically equals Stage IV
False
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
Radiographic bone loss alone cannot diagnose
Periodontitis
A patient can have severe bone loss but a low grade (Grade A)
True-Grade is about speed, not amount
