Key Points: Stage IV Stage I Stage III Stage II ≥5 teeth lost and severe ridge defects indicate Stage IV 2 / 20 Which HbA1c value modifies to Grade C? <6.5% <7.0% No diabetes ≥7.0% HbA1c ≥7.0% in patients with diabetes modifies to Grade C 3 / 20 Grade C direct progression is indicated by what bone loss over 5 years? ≥3mm >4mm ≥2mm <2mm Grade C shows rapid rate with ≥2mm loss over 5 years 4 / 20 What HbA1c level in diabetic patients indicates Grade B? ≥7.0% <6.5% <7.0% No diabetes HbA1c <7.0% in patients with diabetes indicates Grade B -Diabetes has an impact on grading depending on the level of HbA1c. 5 / 20 What is direct evidence of Grade A progression? No loss over 5 years 1mm over 5 years ≥2mm over 5 years <2mm over 5 years Grade A shows slow rate with no loss over 5 years 6 / 20 Patient has probing depths ≤4mm, horizontal bone loss <15%, non-smoker, normal glucose. What stage and grade? Stage I, Grade A Stage II, Grade B Stage I, Grade B Stage II, Grade A PD and bone loss indicate Stage I, risk factors indicate Grade A 7 / 20 What case phenotype indicates Grade B? Destruction exceeds biofilm expectations Destruction commensurate with biofilm Minimal biofilm Heavy biofilm, low destruction Destruction commensurate with biofilm deposits 8 / 20 Grade C smoking modifier is defined as? Any smoking ≥10 cigarettes/day <10 cigarettes/day Non-smoker ≥10 cigarettes/day modifies to Grade C 9 / 20 What characterizes Grade C case phenotype? Heavy biofilm with a low level of destruction Destruction exceeds expectations, given biofilm deposits Periodontal destruction matches biofilm deposits Minimal biofilm deposits with minimal destruction The level of destruction exceeds expectations given the biofilm deposits. 10 / 20 For extent description, what are the three possible patterns? Mild/Mod/Severe Early/Late/Advanced Localized/Generalized/Molar-Incisor None of above Extent described as localized, generalized, or molar/incisor pattern 11 / 20 What diabetes status indicates Grade A? Normoglycemic/no diabetes Any diabetes HbA1c <7.0% HbA1c ≥7.0% Normoglycemic/no diagnosis of diabetes indicates Grade A 12 / 20 How is “localized” periodontitis defined? <30% teeth <40% teeth <20% teeth <10% teeth Classification defines localized as <30% of teeth involved 13 / 20 Which Stage first presents with vertical bone loss ≥3mm? Stage II Stage IV Stage I Stage III Vertical bone loss ≥3mm first appears in Stage III complexity factors 14 / 20 When CAL is not available, what should be used for staging? RBL Bleeding on probing Mobility Probing depth Classification states RBL should be used if CAL unavailable 15 / 20 What bone loss/age % indicates Grade B? 0.25 to 1.0 <0.25 2 >1.0 Grade B shows moderate rate with bone loss/age ratio 0.25 to 1.0 16 / 20 At what location is RBL measured? Average of all sites Most affected site Least affected site Random site RBL is measured at site of greatest loss 17 / 20 Which type of bone loss is predominantly seen in Stage I and II? Neither Both equally Vertical Horizontal Stages I and II show mostly horizontal bone loss 18 / 20 Stage III and IV share which CAL measurement? <1mm ≥5mm 1-2mm 3-4mm Both Stage III and IV show CAL ≥5mm 19 / 20 What characterizes Grade A case phenotype? Exceeds biofilm expectations Minimal biofilm Heavy biofilm, low destruction Matches biofilm deposits Heavy biofilm deposits with low levels of destruction 20 / 20 In Stage I and II, how many teeth are lost due to periodontitis? 3-4 teeth 1-2 teeth No tooth loss >4 teeth Stages I and II show no tooth loss due to periodontitis 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
