Any smoking <10 cigarettes/day ≥10 cigarettes/day Non-smoker Non-smoker status indicates Grade A 2 / 20 Which stage first considers tooth loss as a staging criterion? Stage III Stage II Stage IV Stage I Tooth loss first appears as a criterion in Stage III 3 / 20 Which type of bone loss is predominantly seen in Stage I and II? Vertical Both equally Neither Horizontal Stages I and II show mostly horizontal bone loss 4 / 20 What smoking history indicates Grade B? ≥10 cigarettes/day Non-smoker Any smoking <10 cigarettes/day <10 cigarettes/day modifies to Grade B 5 / 20 Which is NOT a complexity factor in Stage IV? Secondary occlusal trauma Masticatory dysfunction Bite collapse Horizontal bone loss Horizontal bone loss is not a specific Stage IV complexity factor 6 / 20 Which stage first presents with furcation involvement? Stage IV Stage II Stage I Stage III Furcation Class II or III first appears in Stage III complexity 7 / 20 What HbA1c level in diabetic patients indicates Grade B? No diabetes <6.5% ≥7.0% <7.0% HbA1c <7.0% in patients with diabetes indicates Grade B -Diabetes has an impact on grading depending on the level of HbA1c. 8 / 20 What case phenotype indicates Grade B? Minimal biofilm Heavy biofilm, low destruction Destruction commensurate with biofilm Destruction exceeds biofilm expectations Destruction commensurate with biofilm deposits 9 / 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. 10 / 20 How is “localized” periodontitis defined? <40% teeth <30% teeth <10% teeth <20% teeth Classification defines localized as <30% of teeth involved 11 / 20 When CAL is not available, what should be used for staging? Probing depth Mobility Bleeding on probing RBL Classification states RBL should be used if CAL unavailable 12 / 20 What is the indirect evidence of Grade A progression (% bone loss/age)? None >1.0 <0.25 0.25 to 1.0 Grade A indirect evidence is <0.25 bone loss/age ratio 13 / 20 What bone loss/age % indicates Grade B? >1.0 0.25 to 1.0 2 <0.25 Grade B shows moderate rate with bone loss/age ratio 0.25 to 1.0 14 / 20 Which Stage first presents with vertical bone loss ≥3mm? Stage III Stage IV Stage II Stage I Vertical bone loss ≥3mm first appears in Stage III complexity factors 15 / 20 What’s the minimum criteria needed to shift to Stage IV? Furcation involvement RBL below middle third of the root Vertical bone loss ≥5 teeth lost ≥5 teeth lost automatically moves to Stage IV 16 / 20 How many opposing pairs of teeth indicate potential masticatory dysfunction in Stage IV? <12 pairs <10 pairs <9 pairs <8 pairs <10 opposing pairs (20 teeth) indicates masticatory dysfunction 17 / 20 In assessing tooth loss for staging, what type of tooth loss is counted? All missing teeth Only anterior teeth Only posterior teeth Only periodontitis-related loss Only teeth lost due to periodontitis are considered in staging 18 / 20 Grade C smoking modifier is defined as? <10 cigarettes/day Any smoking ≥10 cigarettes/day Non-smoker ≥10 cigarettes/day modifies to Grade C 19 / 20 In Stage II periodontitis, what is the CAL range? 1-2mm ≥5mm <1mm 3-4mm Stage II is characterized by 3-4mm interdental CAL 20 / 20 Which HbA1c value modifies to Grade C? No diabetes <6.5% ≥7.0% <7.0% HbA1c ≥7.0% in patients with diabetes modifies to Grade C 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
