Probing depth ≤4mm + vertical bone loss Probing depth ≥6mm + Class II furcation Probing depth ≥6mm + mobility 1 Probing depth ≤5mm + horizontal bone loss Stage III includes probing depths ≥6mm and Class II furcations 6 / 20 Which grade should clinicians initially assume? Grade A Grade C No grade Grade B Clinicians should initially assume Grade B Key Points: 7 / 20 At what location is RBL measured? Random site Least affected site Average of all sites Most affected site RBL is measured at site of greatest loss 8 / 20 When is extent considered “localized”? <20% teeth <30% teeth <40% teeth <10% teeth Localized is defined as <30% of teeth involved 9 / 20 What is the CAL measurement range for Stage I periodontitis? <1mm ≥5mm 1-2mm 3-4mm Stage I shows interdental CAL of 1-2mm as the earliest detectable stage CAL progression through stages: 10 / 20 What degree of mobility indicates Stage IV complexity? ≥3 Any mobility ≥1 ≥2 Tooth mobility degree ≥2 is a Stage IV complexity factor 11 / 20 Grade C smoking modifier is defined as? Non-smoker ≥10 cigarettes/day <10 cigarettes/day Any smoking ≥10 cigarettes/day modifies to Grade C 12 / 20 If a patient has lost 6 teeth due to periodontitis but has Stage II CAL/RBL, what stage would they be? Stage IV Stage II Stage I Stage III Tooth loss can modify stage definition – ≥5 teeth lost moves to Stage IV regardless of other factors 13 / 20 In Stage I periodontitis, what is the interdental CAL measurement? 1-2 mm ≥5 mm >6 mm 3-4 mm Stage I shows earliest CAL with interdental CAL of 1-2mm as specified in classification 14 / 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 15 / 20 What diabetes status indicates Grade A? Any diabetes HbA1c ≥7.0% HbA1c <7.0% Normoglycemic/no diabetes Normoglycemic/no diagnosis of diabetes indicates Grade A 16 / 20 In Stage II periodontitis, what is the CAL range? 3-4mm ≥5mm 1-2mm <1mm Stage II is characterized by 3-4mm interdental CAL 17 / 20 Stage II RBL is described as what percentage? 15-33% >50% <15% 33-50% Stage II shows coronal third RBL 15-33% 18 / 20 What characterizes bone loss pattern in Stage I and II? Both Horizontal Vertical Neither Stages I and II show mostly horizontal bone loss patterns 19 / 20 What’s the minimum criteria needed to shift to Stage IV? Vertical bone loss ≥5 teeth lost RBL below middle third of the root Furcation involvement ≥5 teeth lost automatically moves to Stage IV 20 / 20 How many teeth lost due to periodontitis indicates Stage IV? ≥4 teeth ≥5 teeth ≥3 teeth ≥6 teeth Stage IV shows ≥5 teeth lost 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
