No grade Grade C Grade B Grade A Clinicians should initially assume Grade B Key Points: 4 / 20 Which type of bone loss is predominantly seen in Stage I and II? Both equally Neither Vertical Horizontal Stages I and II show mostly horizontal bone loss 5 / 20 What HbA1c level in diabetic patients indicates Grade B? ≥7.0% <6.5% No diabetes <7.0% HbA1c <7.0% in patients with diabetes indicates Grade B -Diabetes has an impact on grading depending on the level of HbA1c. 6 / 20 At what location is RBL measured? Random site Most affected site Least affected site Average of all sites RBL is measured at site of greatest loss 7 / 20 How many teeth lost due to periodontitis indicates Stage IV? ≥5 teeth ≥3 teeth ≥4 teeth ≥6 teeth Stage IV shows ≥5 teeth lost due to periodontitis 8 / 20 What characterizes Grade A case phenotype? Heavy biofilm, low destruction Minimal biofilm Exceeds biofilm expectations Matches biofilm deposits Heavy biofilm deposits with low levels of destruction 9 / 20 What is the indirect evidence of Grade A progression (% bone loss/age)? 0.25 to 1.0 None <0.25 >1.0 Grade A indirect evidence is <0.25 bone loss/age ratio 10 / 20 Which stage first considers tooth loss as a staging criterion? Stage II Stage IV Stage III Stage I Tooth loss first appears as a criterion in Stage III 11 / 20 Which stage first presents with furcation involvement? Stage IV Stage I Stage II Stage III Furcation Class II or III first appears in Stage III complexity 12 / 20 What case phenotype indicates Grade B? Destruction commensurate with biofilm Heavy biofilm, low destruction Minimal biofilm Destruction exceeds biofilm expectations Destruction commensurate with biofilm deposits 13 / 20 What is direct evidence of Grade A progression? <2mm over 5 years ≥2mm over 5 years No loss over 5 years 1mm over 5 years Grade A shows slow rate with no loss over 5 years 14 / 20 How is “localized” periodontitis defined? <40% teeth <10% teeth <30% teeth <20% teeth Classification defines localized as <30% of teeth involved 15 / 20 Stage II RBL is described as what percentage? 33-50% >50% <15% 15-33% Stage II shows coronal third RBL 15-33% 16 / 20 What HbA1c level in diabetic patients indicates Grade C? >7.0% >6.0% >6.5% >8.0% HbA1c ≥7.0% in patients with diabetes indicates Grade C 17 / 20 Patient has probing depths ≤4mm, horizontal bone loss <15%, non-smoker, normal glucose. What stage and grade? Stage I, Grade A Stage I, Grade B Stage II, Grade A Stage II, Grade B PD and bone loss indicate Stage I, risk factors indicate Grade A 18 / 20 How many opposing pairs of teeth indicate potential masticatory dysfunction in Stage IV? <10 pairs <9 pairs <12 pairs <8 pairs <10 opposing pairs (20 teeth) indicates masticatory dysfunction 19 / 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 20 / 20 What’s the minimum criteria needed to shift to Stage IV? Furcation involvement RBL below middle third of the root ≥5 teeth lost Vertical bone loss ≥5 teeth lost automatically moves to Stage IV 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
