Minimal biofilm Heavy biofilm, low destruction Destruction commensurate with biofilm Destruction exceeds biofilm expectations Destruction commensurate with biofilm deposits 4 / 20 In absence of CAL measurements, what primary criteria is used? Bleeding Probing depth Mobility Bone loss Radiographic bone loss is used when CAL unavailable 5 / 20 What smoking history indicates Grade B? <10 cigarettes/day Non-smoker ≥10 cigarettes/day Any smoking <10 cigarettes/day modifies to Grade B 6 / 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 7 / 20 What smoking status indicates Grade A? ≥10 cigarettes/day <10 cigarettes/day Any smoking Non-smoker Non-smoker status indicates Grade A 8 / 20 What is considered bite collapse in Stage IV? <15 teeth <18 teeth <20 teeth <22 teeth <20 remaining teeth (10 opposing pairs) indicates bite collapse in Stage IV 9 / 20 For extent description, what are the three possible patterns? Localized/Generalized/Molar-Incisor Early/Late/Advanced Mild/Mod/Severe None of above Extent described as localized, generalized, or molar/incisor pattern 10 / 20 What HbA1c level in diabetic patients indicates Grade B? ≥7.0% No diabetes <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 Which type of bone loss is predominantly seen in Stage I and II? Vertical Neither Both equally Horizontal Stages I and II show mostly horizontal bone loss 12 / 20 Patient with HbA1c 7.2% who never smoked would be modified to what grade? Grade C Grade B Grade A Can't determine HbA1c ≥7.0% modifies to Grade C, even without smoking 13 / 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] 14 / 20 What degree of mobility indicates Stage IV complexity? ≥3 ≥1 Any mobility ≥2 Tooth mobility degree ≥2 is a Stage IV complexity factor 15 / 20 Grade C smoking modifier is defined as? <10 cigarettes/day Any smoking ≥10 cigarettes/day Non-smoker ≥10 cigarettes/day modifies to Grade C 16 / 20 Stage III and IV share which CAL measurement? ≥5mm <1mm 3-4mm 1-2mm Both Stage III and IV show CAL ≥5mm 17 / 20 When CAL is not available, what should be used for staging? Probing depth Bleeding on probing RBL Mobility Classification states RBL should be used if CAL unavailable 18 / 20 What defines “bite collapse” in Stage IV? <20 teeth <15 teeth All of above <10 opposing pairs <20 remaining teeth (10 opposing pairs) indicates bite collapse 19 / 20 What characterizes bone loss pattern in Stage I and II? Both Neither Vertical Horizontal Stages I and II show mostly horizontal bone loss patterns 20 / 20 What characterizes Grade A case phenotype? Heavy biofilm, low destruction Matches biofilm deposits Minimal biofilm Exceeds biofilm expectations Heavy biofilm deposits with low levels of destruction 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
