Minimal biofilm Exceeds biofilm expectations Matches biofilm deposits Heavy biofilm, low destruction Heavy biofilm deposits with low levels of destruction 3 / 20 Stage III and IV share which CAL measurement? ≥5mm 3-4mm 1-2mm <1mm Both Stage III and IV show CAL ≥5mm 4 / 20 Grade C smoking modifier is defined as? Any smoking <10 cigarettes/day ≥10 cigarettes/day Non-smoker ≥10 cigarettes/day modifies to Grade C 5 / 20 In absence of CAL measurements, what primary criteria is used? Probing depth Bone loss Bleeding Mobility Radiographic bone loss is used when CAL unavailable 6 / 20 What smoking history indicates Grade B? Non-smoker Any smoking <10 cigarettes/day ≥10 cigarettes/day <10 cigarettes/day modifies to Grade B 7 / 20 In Stage I and II, how many teeth are lost due to periodontitis? 3-4 teeth 1-2 teeth No tooth loss >4 teeth Stages I and II show no tooth loss due to periodontitis 8 / 20 What defines “bite collapse” in Stage IV? All of above <20 teeth <15 teeth <10 opposing pairs <20 remaining teeth (10 opposing pairs) indicates bite collapse 9 / 20 What is maximum probing depth in Stage I? ≤5 mm ≤3 mm ≤4 mm ≤6 mm Stage I complexity shows maximum probing depth ≤4 mm 10 / 20 What smoking status indicates Grade A? ≥10 cigarettes/day Non-smoker <10 cigarettes/day Any smoking Non-smoker status indicates Grade A 11 / 20 Which stage first considers tooth loss as a staging criterion? Stage IV Stage II Stage I Stage III Tooth loss first appears as a criterion in Stage III 12 / 20 At what location is RBL measured? Least affected site Most affected site Average of all sites Random site RBL is measured at site of greatest loss 13 / 20 Which stage first presents with furcation involvement? Stage III Stage II Stage IV Stage I Furcation Class II or III first appears in Stage III complexity 14 / 20 Which type of bone loss is predominantly seen in Stage I and II? Neither Horizontal Both equally Vertical Stages I and II show mostly horizontal bone loss 15 / 20 Patient with HbA1c 7.2% who never smoked would be modified to what grade? Grade A Grade C Can't determine Grade B HbA1c ≥7.0% modifies to Grade C, even without smoking 16 / 20 What characterizes Grade C case phenotype? Minimal biofilm deposits with minimal destruction Heavy biofilm with a low level of destruction Destruction exceeds expectations, given biofilm deposits Periodontal destruction matches biofilm deposits The level of destruction exceeds expectations given the biofilm deposits. 17 / 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 III Stage I Stage II Tooth loss can modify stage definition – ≥5 teeth lost moves to Stage IV regardless of other factors 18 / 20 When CAL is not available, what should be used for staging? Probing depth Bleeding on probing Mobility RBL Classification states RBL should be used if CAL unavailable 19 / 20 For extent description, what are the three possible patterns? Mild/Mod/Severe None of above Localized/Generalized/Molar-Incisor Early/Late/Advanced Extent described as localized, generalized, or molar/incisor pattern 20 / 20 When is extent considered “localized”? <10% teeth <20% teeth <40% teeth <30% teeth Localized is defined as <30% of teeth involved 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
