Any diabetes HbA1c ≥7.0% HbA1c <7.0% Normoglycemic/no diabetes Normoglycemic/no diagnosis of diabetes indicates Grade A 4 / 20 What bone loss/age % indicates Grade B? 0.25 to 1.0 <0.25 >1.0 2 Grade B shows moderate rate with bone loss/age ratio 0.25 to 1.0 5 / 20 In Stage II, what is the maximum probing depth? ≤6 mm ≤5 mm ≤7 mm ≤4 mm Stage II complexity shows maximum probing depth ≤5 mm 6 / 20 What indicates Grade C progression based on radiographic bone loss over 5 years? <2 mm ≥2 mm No loss <1 mm Grade C shows rapid progression with ≥2mm bone loss over 5 years 7 / 20 In Stage I and II, how many teeth are lost due to periodontitis? >4 teeth No tooth loss 3-4 teeth 1-2 teeth Stages I and II show no tooth loss due to periodontitis 8 / 20 When do vertical bone defects ≥3mm first appear as a complexity factor? Stage II Stage III Stage I Stage IV Vertical bone loss ≥3mm first appears in Stage III 9 / 20 Which is NOT a complexity factor in Stage IV? Secondary occlusal trauma Masticatory dysfunction Horizontal bone loss Bite collapse Horizontal bone loss is not a specific Stage IV complexity factor 10 / 20 If a patient has lost 6 teeth due to periodontitis but has Stage II CAL/RBL, what stage would they be? Stage II Stage III Stage IV Stage I Tooth loss can modify stage definition – ≥5 teeth lost moves to Stage IV regardless of other factors 11 / 20 What characterizes bone loss pattern in Stage I and II? Neither Both Horizontal Vertical Stages I and II show mostly horizontal bone loss patterns 12 / 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 A Stage II, Grade B Stage I, Grade B PD and bone loss indicate Stage I, risk factors indicate Grade A 13 / 20 In assessing tooth loss for staging, what type of tooth loss is counted? Only periodontitis-related loss All missing teeth Only posterior teeth Only anterior teeth Only teeth lost due to periodontitis are considered in staging 14 / 20 Stage II maximum probing depth is? ≤5 mm ≤7 mm ≤4 mm ≤6 mm Stage II complexity shows maximum probing depth ≤5 mm 15 / 20 In Stage II periodontitis, what is the CAL range? 1-2mm 3-4mm <1mm ≥5mm Stage II is characterized by 3-4mm interdental CAL 16 / 20 Which combination indicates Stage III complexity? Probing depth ≤5mm + horizontal bone loss Probing depth ≥6mm + Class II furcation Probing depth ≥6mm + mobility 1 Probing depth ≤4mm + vertical bone loss Stage III includes probing depths ≥6mm and Class II furcations 17 / 20 Which type of bone loss is predominantly seen in Stage I and II? Horizontal Vertical Both equally Neither Stages I and II show mostly horizontal bone loss 18 / 20 When CAL is not available, what should be used for staging? Probing depth RBL Bleeding on probing Mobility Classification states RBL should be used if CAL unavailable 19 / 20 Patient with HbA1c 7.2% who never smoked would be modified to what grade? Grade A Can't determine Grade B Grade C HbA1c ≥7.0% modifies to Grade C, even without smoking 20 / 20 What is the CAL measurement range for Stage I periodontitis? <1mm ≥5mm 3-4mm 1-2mm Stage I shows interdental CAL of 1-2mm as the earliest detectable stage CAL progression through stages: 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
