Stage I Stage IV Stage II Stage III Vertical bone loss ≥3mm first appears in Stage III complexity factors 9 / 20 Patient has probing depths ≤4mm, horizontal bone loss <15%, non-smoker, normal glucose. What stage and grade? Stage II, Grade B Stage II, Grade A Stage I, Grade A Stage I, Grade B PD and bone loss indicate Stage I, risk factors indicate Grade A 10 / 20 What defines “bite collapse” in Stage IV? <15 teeth <20 teeth All of above <10 opposing pairs <20 remaining teeth (10 opposing pairs) indicates bite collapse 11 / 20 Patient with HbA1c 7.2% who never smoked would be modified to what grade? Can't determine Grade C Grade A Grade B HbA1c ≥7.0% modifies to Grade C, even without smoking 12 / 20 What smoking status indicates Grade A? ≥10 cigarettes/day Non-smoker <10 cigarettes/day Any smoking Non-smoker status indicates Grade A 13 / 20 What % bone loss/age ratio indicates Grade B? >1.0 >2.0 <0.25 0.25-1.0 Grade B shows moderate progression with bone loss/age ratio of 0.25-1.0 14 / 20 Stage III and IV share which CAL measurement? ≥5mm 3-4mm <1mm 1-2mm Both Stage III and IV show CAL ≥5mm 15 / 20 If a patient has lost 6 teeth due to periodontitis but has Stage II CAL/RBL, what stage would they be? Stage II Stage III Stage I Stage IV Tooth loss can modify stage definition – ≥5 teeth lost moves to Stage IV regardless of other factors 16 / 20 What characterizes Grade C case phenotype? Minimal biofilm deposits with minimal destruction Periodontal destruction matches biofilm deposits Destruction exceeds expectations, given biofilm deposits Heavy biofilm with a low level of destruction The level of destruction exceeds expectations given the biofilm deposits. 17 / 20 Which is NOT a complexity factor in Stage IV? Masticatory dysfunction Horizontal bone loss Secondary occlusal trauma Bite collapse Horizontal bone loss is not a specific Stage IV complexity factor 18 / 20 What is maximum probing depth in Stage I? ≤3 mm ≤4 mm ≤6 mm ≤5 mm Stage I complexity shows maximum probing depth ≤4 mm 19 / 20 What HbA1c level in diabetic patients indicates Grade C? >8.0% >6.0% >6.5% >7.0% HbA1c ≥7.0% in patients with diabetes indicates Grade C 20 / 20 In absence of CAL measurements, what primary criteria is used? Mobility Bleeding Probing depth Bone loss Radiographic bone loss is used when CAL unavailable 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
