Average of all sites Most affected site Random site Least affected site RBL is measured at site of greatest loss 2 / 20 Which is NOT a complexity factor in Stage IV? Bite collapse Horizontal bone loss Masticatory dysfunction Secondary occlusal trauma Horizontal bone loss is not a specific Stage IV complexity factor 3 / 20 How is “localized” periodontitis defined? <30% teeth <20% teeth <40% teeth <10% teeth Classification defines localized as <30% of teeth involved 4 / 20 What defines “bite collapse” in Stage IV? <10 opposing pairs All of above <20 teeth <15 teeth <20 remaining teeth (10 opposing pairs) indicates bite collapse 5 / 20 Which HbA1c value modifies to Grade C? <6.5% No diabetes ≥7.0% <7.0% HbA1c ≥7.0% in patients with diabetes modifies to Grade C 6 / 20 What degree of mobility indicates Stage IV complexity? Any mobility ≥3 ≥2 ≥1 Tooth mobility degree ≥2 is a Stage IV complexity factor 7 / 20 For extent description, what are the three possible patterns? Mild/Mod/Severe None of above Early/Late/Advanced Localized/Generalized/Molar-Incisor Extent described as localized, generalized, or molar/incisor pattern 8 / 20 How many teeth lost due to periodontitis indicates Stage IV? ≥5 teeth ≥4 teeth ≥6 teeth ≥3 teeth Stage IV shows ≥5 teeth lost due to periodontitis 9 / 20 Stage III and IV share which CAL measurement? 1-2mm ≥5mm <1mm 3-4mm Both Stage III and IV show CAL ≥5mm 10 / 20 What bone loss/age % indicates Grade B? >1.0 0.25 to 1.0 <0.25 2 Grade B shows moderate rate with bone loss/age ratio 0.25 to 1.0 11 / 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 I, Grade B Stage II, Grade B PD and bone loss indicate Stage I, risk factors indicate Grade A 12 / 20 What is the radiographic bone loss (RBL) percentage in Stage I? >50% 15-33% 33-50% <15% Stage I shows coronal third RBL <15% RBL is assessed at the site of greatest loss, due to periodontal disease. The following formulas are used to calculate RBL: BL: % of bone loss=(CEJ-Alveolar Crest)÷(CEJ-Apex) x 100 RBL = % of bone loss/Age = BL÷ Patient’s Age [CE Course: The A, B, Cs, and I, II, and IIIs of Periodontitis Staging and Grading By: Fran Soderling, RDH, MA and Jila Torabi, RDH, MPH] 13 / 20 What HbA1c level in diabetic patients indicates Grade C? >6.0% >8.0% >7.0% >6.5% HbA1c ≥7.0% in patients with diabetes indicates Grade C 14 / 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 15 / 20 What diabetes status indicates Grade A? HbA1c <7.0% Any diabetes HbA1c ≥7.0% Normoglycemic/no diabetes Normoglycemic/no diagnosis of diabetes indicates Grade A 16 / 20 What is maximum probing depth in Stage I? ≤5 mm ≤6 mm ≤4 mm ≤3 mm Stage I complexity shows maximum probing depth ≤4 mm 17 / 20 What characterizes Grade A case phenotype? Exceeds biofilm expectations Heavy biofilm, low destruction Matches biofilm deposits Minimal biofilm Heavy biofilm deposits with low levels of destruction 18 / 20 How many teeth lost due to periodontitis indicates Stage III? ≤2 teeth ≤5 teeth ≤3 teeth ≤4 teeth Stage III is characterized by ≤4 teeth lost due to periodontitis 19 / 20 Stage II maximum probing depth is? ≤7 mm ≤4 mm ≤6 mm ≤5 mm Stage II complexity shows maximum probing depth ≤5 mm 20 / 20 Stage II RBL is described as what percentage? >50% 33-50% <15% 15-33% Stage II shows coronal third RBL 15-33% 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
