Heavy biofilm, low destruction Minimal biofilm Matches biofilm deposits Exceeds biofilm expectations Heavy biofilm deposits with low levels of destruction 4 / 20 Which combination indicates Stage III complexity? Probing depth ≤5mm + horizontal bone loss Probing depth ≤4mm + vertical bone loss Probing depth ≥6mm + mobility 1 Probing depth ≥6mm + Class II furcation Stage III includes probing depths ≥6mm and Class II furcations 5 / 20 What is considered bite collapse in Stage IV? <20 teeth <15 teeth <22 teeth <18 teeth <20 remaining teeth (10 opposing pairs) indicates bite collapse in Stage IV 6 / 20 What defines “bite collapse” in Stage IV? <20 teeth <10 opposing pairs All of above <15 teeth <20 remaining teeth (10 opposing pairs) indicates bite collapse 7 / 20 How many teeth lost due to periodontitis indicates Stage IV? ≥3 teeth ≥4 teeth ≥6 teeth ≥5 teeth Stage IV shows ≥5 teeth lost due to periodontitis 8 / 20 Which is NOT a complexity factor in Stage IV? Bite collapse Masticatory dysfunction Secondary occlusal trauma Horizontal bone loss Horizontal bone loss is not a specific Stage IV complexity factor 9 / 20 Patient with HbA1c 7.2% who never smoked would be modified to what grade? Grade B Can't determine Grade C Grade A HbA1c ≥7.0% modifies to Grade C, even without smoking 10 / 20 What bone loss/age % indicates Grade B? >1.0 <0.25 0.25 to 1.0 2 Grade B shows moderate rate with bone loss/age ratio 0.25 to 1.0 11 / 20 What case phenotype indicates Grade B? Heavy biofilm, low destruction Destruction exceeds biofilm expectations Destruction commensurate with biofilm Minimal biofilm Destruction commensurate with biofilm deposits 12 / 20 What is the CAL measurement range for Stage I periodontitis? ≥5mm 3-4mm <1mm 1-2mm Stage I shows interdental CAL of 1-2mm as the earliest detectable stage CAL progression through stages: 13 / 20 Stage III and IV share which CAL measurement? ≥5mm 3-4mm 1-2mm <1mm Both Stage III and IV show CAL ≥5mm 14 / 20 Which Stage first presents with vertical bone loss ≥3mm? Stage III Stage I Stage IV Stage II Vertical bone loss ≥3mm first appears in Stage III complexity factors 15 / 20 Grade C smoking modifier is defined as? ≥10 cigarettes/day Any smoking Non-smoker <10 cigarettes/day ≥10 cigarettes/day modifies to Grade C 16 / 20 What is direct evidence of Grade A progression? <2mm over 5 years No loss over 5 years ≥2mm over 5 years 1mm over 5 years Grade A shows slow rate with no loss over 5 years 17 / 20 Which HbA1c value modifies to Grade C? <7.0% <6.5% ≥7.0% No diabetes HbA1c ≥7.0% in patients with diabetes modifies to Grade C 18 / 20 When do vertical bone defects ≥3mm first appear as a complexity factor? Stage IV Stage II Stage III Stage I Vertical bone loss ≥3mm first appears in Stage III 19 / 20 What % bone loss/age ratio indicates Grade B? <0.25 0.25-1.0 >1.0 >2.0 Grade B shows moderate progression with bone loss/age ratio of 0.25-1.0 20 / 20 What is maximum probing depth in Stage I? ≤6 mm ≤4 mm ≤5 mm ≤3 mm Stage I complexity shows maximum probing depth ≤4 mm 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
