Study Notes
Periodontitis Grading
- Grading assesses the rate of progression and risk of future disease in periodontitis.
- Classification includes slow, moderate, or rapid progression.
- Direct evidence of progression is determined by radiographic bone loss (RBL) over a 5-year period.
- A: No RBL
- B: RBL < 2mm
- C: RBL > 2mm
- Indirect evidence involves a biofilm destruction ratio using a % BL equation.
- A: % BL < 0.25 (heavy biofilm, low destruction)
- B: % BL 0.25 - 1 (destruction commensurate with biofilm)
- C: % BL > 1 (destruction exceeds biofilm)
Risk Factors
- Risk factors in periodontitis grading include smoking and diabetes status.
- A: Non-smoker, non-diabetic
- B: Less than 10 cigarettes/day; A1c < 7
- C: 10 or more cigarettes/day; A1c ≥ 7
RBL Equation
- Radiographic bone loss is calculated using the formula: % bone loss / age of patient.
AAP Periodontal Classification
- Categories from 0-4 mm probing depth indicate gingivitis.
Gingivitis Definitions
- Probing depth: 0-1 mm
- Clinical attachment loss: None detected
- Radiographic bone loss: None detected
- Tooth mobility and furcation involvement: None detected
Periodontitis Staging
- Stages of periodontitis are categorized by severity:
- Slight - Stage I
- Moderate - Stage II
- Severe - Stage III
- Severe + - Stage IV
Treatment Capacities
- General dentists can treat gingivitis, Stage I, and Stage II periodontitis.
- Stage III and IV require treatment by a periodontist.
Periodontitis Definitions
- Probing depth at various stages:
- Stage I: 4-5mm
- Stage II: 5-6mm
- Stage III and IV: > 6mm
- Clinical attachment loss stages:
- Stage I: 1-2mm
- Stage II: 3-4mm
- Stage III and IV: ≥ 5mm
- Radiographic bone loss:
- Stage I: < 15% horizontal bone loss
- Stage II: 15-33% horizontal bone loss
- Stage III and IV: > 33% vertical bone loss
- Mobility/tooth loss classifications:
- Stage I: Class I mobility
- Stage II: Class II mobility
- Stage III: Class III mobility in 30% of teeth
Extent of Disease
- Localized extent: < 30% of teeth affected.
- Generalized extent requires a condition affecting at least:
- 10 teeth (for 32 teeth)
- 8 teeth (for 28 teeth)
Grading of Periodontitis Progression
- Grading is determined by evidence of radiographic bone loss and associated risk factors.
- Assessment includes history of radiographs over 5 years and calculating bone loss in relation to patient age.
Host Factors
- Host factors encompass medical history and lifestyle conditions that can influence the progression or management of periodontal disease.
