Probing depth Bone loss Bleeding Mobility Radiographic bone loss is used when CAL unavailable 2 / 20 In Stage I and II, how many teeth are lost due to periodontitis? No tooth loss >4 teeth 3-4 teeth 1-2 teeth Stages I and II show no tooth loss due to periodontitis 3 / 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 4 / 20 What diabetes status indicates Grade A? Any diabetes HbA1c ≥7.0% Normoglycemic/no diabetes HbA1c <7.0% Normoglycemic/no diagnosis of diabetes indicates Grade A 5 / 20 For extent description, what are the three possible patterns? Early/Late/Advanced Mild/Mod/Severe Localized/Generalized/Molar-Incisor None of above Extent described as localized, generalized, or molar/incisor pattern 6 / 20 What smoking status indicates Grade A? Any smoking <10 cigarettes/day Non-smoker ≥10 cigarettes/day Non-smoker status indicates Grade A 7 / 20 If a patient smokes 12 cigarettes/day but has HbA1c of 6.5%, what’s the worst grade modifier? Can't determine Grade C Grade B Grade A Smoking ≥10 cigarettes/day indicates Grade C, regardless of HbA1c 8 / 20 How many teeth lost due to periodontitis indicates Stage IV? ≥6 teeth ≥3 teeth ≥5 teeth ≥4 teeth Stage IV shows ≥5 teeth lost due to periodontitis 9 / 20 What HbA1c level in diabetic patients indicates Grade C? >8.0% >7.0% >6.5% >6.0% HbA1c ≥7.0% in patients with diabetes indicates Grade C 10 / 20 What HbA1c level in diabetic patients indicates Grade B? No diabetes <7.0% ≥7.0% <6.5% HbA1c <7.0% in patients with diabetes indicates Grade B -Diabetes has an impact on grading depending on the level of HbA1c. 11 / 20 What is the indirect evidence of Grade A progression (% bone loss/age)? 0.25 to 1.0 >1.0 None <0.25 Grade A indirect evidence is <0.25 bone loss/age ratio 12 / 20 How many teeth lost due to periodontitis indicates Stage III? ≤4 teeth ≤5 teeth ≤2 teeth ≤3 teeth Stage III is characterized by ≤4 teeth lost due to periodontitis 13 / 20 Which combination indicates Stage III complexity? Probing depth ≤4mm + vertical bone loss Probing depth ≥6mm + Class II furcation Probing depth ≤5mm + horizontal bone loss Probing depth ≥6mm + mobility 1 Stage III includes probing depths ≥6mm and Class II furcations 14 / 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 15 / 20 When CAL is not available, what should be used for staging? Bleeding on probing RBL Mobility Probing depth Classification states RBL should be used if CAL unavailable 16 / 20 Patient with HbA1c 7.2% who never smoked would be modified to what grade? Grade C Can't determine Grade B Grade A HbA1c ≥7.0% modifies to Grade C, even without smoking 17 / 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 18 / 20 Stage III and IV share which CAL measurement? ≥5mm 1-2mm 3-4mm <1mm Both Stage III and IV show CAL ≥5mm 19 / 20 Which grade should clinicians initially assume? No grade Grade A Grade C Grade B Clinicians should initially assume Grade B Key Points: 20 / 20 At what location is RBL measured? Least affected site Most affected site Average of all sites Random site RBL is measured at site of greatest loss 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
