Stage I Stage IV Stage II Stage III Furcation Class II or III first appears in Stage III complexity 2 / 20 How many opposing pairs of teeth indicate potential masticatory dysfunction in Stage IV? <12 pairs <8 pairs <9 pairs <10 pairs <10 opposing pairs (20 teeth) indicates masticatory dysfunction 3 / 20 What diabetes status indicates Grade A? HbA1c ≥7.0% Normoglycemic/no diabetes Any diabetes HbA1c <7.0% Normoglycemic/no diagnosis of diabetes indicates Grade A 4 / 20 What degree of mobility indicates Stage IV complexity? ≥2 ≥3 ≥1 Any mobility Tooth mobility degree ≥2 is a Stage IV complexity factor 5 / 20 How many teeth lost due to periodontitis indicates Stage III? ≤5 teeth ≤3 teeth ≤4 teeth ≤2 teeth Stage III is characterized by ≤4 teeth lost due to periodontitis 6 / 20 How many teeth lost due to periodontitis indicates Stage IV? ≥4 teeth ≥3 teeth ≥6 teeth ≥5 teeth Stage IV shows ≥5 teeth lost due to periodontitis 7 / 20 In assessing tooth loss for staging, what type of tooth loss is counted? All missing teeth Only anterior teeth Only periodontitis-related loss Only posterior teeth Only teeth lost due to periodontitis are considered in staging 8 / 20 What HbA1c level in diabetic patients indicates Grade B? No diabetes <7.0% <6.5% ≥7.0% HbA1c <7.0% in patients with diabetes indicates Grade B -Diabetes has an impact on grading depending on the level of HbA1c. 9 / 20 Stage II maximum probing depth is? ≤7 mm ≤6 mm ≤5 mm ≤4 mm Stage II complexity shows maximum probing depth ≤5 mm 10 / 20 What defines “bite collapse” in Stage IV? <20 teeth <10 opposing pairs <15 teeth All of above <20 remaining teeth (10 opposing pairs) indicates bite collapse 11 / 20 For extent description, what are the three possible patterns? Early/Late/Advanced None of above Localized/Generalized/Molar-Incisor Mild/Mod/Severe Extent described as localized, generalized, or molar/incisor pattern 12 / 20 In Stage II, what is the maximum probing depth? ≤5 mm ≤4 mm ≤6 mm ≤7 mm Stage II complexity shows maximum probing depth ≤5 mm 13 / 20 Grade C direct progression is indicated by what bone loss over 5 years? <2mm ≥3mm ≥2mm >4mm Grade C shows rapid rate with ≥2mm loss over 5 years 14 / 20 In absence of CAL measurements, what primary criteria is used? Probing depth Bleeding Mobility Bone loss Radiographic bone loss is used when CAL unavailable 15 / 20 What is the CAL measurement range for Stage I periodontitis? 1-2mm <1mm ≥5mm 3-4mm Stage I shows interdental CAL of 1-2mm as the earliest detectable stage CAL progression through stages: 16 / 20 What characterizes bone loss pattern in Stage I and II? Neither Both Vertical Horizontal Stages I and II show mostly horizontal bone loss patterns 17 / 20 Which Stage first presents with vertical bone loss ≥3mm? Stage IV Stage I Stage II Stage III Vertical bone loss ≥3mm first appears in Stage III complexity factors 18 / 20 Stage III and IV share which CAL measurement? ≥5mm <1mm 1-2mm 3-4mm Both Stage III and IV show CAL ≥5mm 19 / 20 Stage IV tooth loss is defined as? ≥5 teeth ≥4 teeth ≥3 teeth ≥6 teeth Stage IV shows ≥5 teeth lost due to periodontitis 20 / 20 What case phenotype indicates Grade B? Destruction exceeds biofilm expectations Heavy biofilm, low destruction Destruction commensurate with biofilm Minimal biofilm Destruction commensurate with biofilm deposits 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
