Week 5 Flashcards
What does a PSR code of ‘0’ indicate?
Healthy
WHO: half of 1st is 2mm., touch black is 3.5 mm, half black is 4.5mm, full black is 5.5mm
What does a PSR code of ‘2’ indicate, and what treatment is typically involved?
Calculus, Clean, correct, OHI (oral hygiene instructions)
What does a PSR code of ‘4’ indicate, and what further assessment and treatment are required?
Pocket ≥ 5.5 mm, Periochart + Quad Tx
When the WHO probe has gone way past the black line, indicating a pocket depth deeper than 5.5mm…
WHO: half of 1st is 2mm., touch black is 3.5 mm, half black is 4.5mm, full black is 5.5mm
What does the asterisk (*) symbol indicate in a PSR score?
Clinical abnormality: furcation involvement, tooth mobility, mucogingival problems, recessions ≥ 3.5 mm, etc.
When is it mandatory to record a full mouth chart in relation to PSR codes?
If there is a code 4 in any sextant
Describe Stage I periodontitis.
is often the initial transition from gingivitis to periodontitis, showing early signs of attachment loss
Describe the main characteristic of Stage II periodontitis.
3-4 mm clinical attachment loss (CAL)
In periodontitis staging, what is used to determine the initial stage if CAL is not available?
Radiographic bone loss (RBL)
How is the extent of periodontitis described?
Localized (<30% of teeth involved), Generalized, or Molar/Incisor pattern
What are the grades of periodontitis, and what do they indicate?
A, B, and C, indicating the rate of progression of the disease
What is the primary assumption for grading periodontitis, and what factors can influence this?
Grade B (moderate progression) is the initial assumption, and clinicians can adjust based on risk assessments, including modifiable factors like diabetes and smoking, biofilm levels, and evidence of progression.
Describe Grade C periodontitis.
Fast progression (>2mm over 5 years), damage beyond biofilm expectation (and/or early onset disease), >10 smokes a day or HbA1c >7% in patients with diabetes
