Average of all sites Most affected site Random site Least affected site RBL is measured at site of greatest loss 3 / 20 Which stage first considers tooth loss as a staging criterion? Stage IV Stage III Stage II Stage I Tooth loss first appears as a criterion in Stage III 4 / 20 What % bone loss/age ratio indicates Grade B? 0.25-1.0 >2.0 >1.0 <0.25 Grade B shows moderate progression with bone loss/age ratio of 0.25-1.0 5 / 20 Which combination indicates Stage III complexity? Probing depth ≥6mm + mobility 1 Probing depth ≤5mm + horizontal bone loss Probing depth ≤4mm + vertical bone loss Probing depth ≥6mm + Class II furcation Stage III includes probing depths ≥6mm and Class II furcations 6 / 20 How many teeth lost due to periodontitis indicates Stage III? ≤2 teeth ≤4 teeth ≤5 teeth ≤3 teeth Stage III is characterized by ≤4 teeth lost due to periodontitis 7 / 20 What is maximum probing depth in Stage I? ≤3 mm ≤4 mm ≤5 mm ≤6 mm Stage I complexity shows maximum probing depth ≤4 mm 8 / 20 Grade C direct progression is indicated by what bone loss over 5 years? <2mm ≥2mm >4mm ≥3mm Grade C shows rapid rate with ≥2mm loss over 5 years 9 / 20 How many teeth lost due to periodontitis indicates Stage IV? ≥5 teeth ≥4 teeth ≥6 teeth ≥3 teeth Stage IV shows ≥5 teeth lost due to periodontitis 10 / 20 What smoking history indicates Grade B? <10 cigarettes/day Non-smoker Any smoking ≥10 cigarettes/day <10 cigarettes/day modifies to Grade B 11 / 20 What bone loss/age % indicates Grade B? 0.25 to 1.0 <0.25 >1.0 2 Grade B shows moderate rate with bone loss/age ratio 0.25 to 1.0 12 / 20 Stage II RBL is described as what percentage? 15-33% <15% >50% 33-50% Stage II shows coronal third RBL 15-33% 13 / 20 Stage II maximum probing depth is? ≤4 mm ≤5 mm ≤7 mm ≤6 mm Stage II complexity shows maximum probing depth ≤5 mm 14 / 20 What is the indirect evidence of Grade A progression (% bone loss/age)? >1.0 0.25 to 1.0 <0.25 None Grade A indirect evidence is <0.25 bone loss/age ratio 15 / 20 Which grade should clinicians initially assume? Grade B No grade Grade A Grade C Clinicians should initially assume Grade B Key Points: 16 / 20 What degree of mobility indicates Stage IV complexity? ≥1 Any mobility ≥3 ≥2 Tooth mobility degree ≥2 is a Stage IV complexity factor 17 / 20 A case with Grade C bone loss/age ratio but Grade B HbA1c and smoking is classified as? Cannot determine Grade B Grade C Grade A Highest grade modifier (C) determines final grade 18 / 20 How many opposing pairs of teeth indicate potential masticatory dysfunction in Stage IV? <8 pairs <10 pairs <12 pairs <9 pairs <10 opposing pairs (20 teeth) indicates masticatory dysfunction 19 / 20 If a patient has lost 6 teeth due to periodontitis but has Stage II CAL/RBL, what stage would they be? Stage I Stage IV Stage II Stage III Tooth loss can modify stage definition – ≥5 teeth lost moves to Stage IV regardless of other factors 20 / 20 What smoking status indicates Grade A? ≥10 cigarettes/day <10 cigarettes/day Any smoking Non-smoker Non-smoker status indicates Grade A Your score is 0% Restart quiz AAPD Staging and Grading Periodontitis AAPD Three Steps to Staging and Grading a Patient CDHA The A, B, Cs, and I, II, and IIIs of Periodontitis Staging
