Destruction exceeds biofilm expectations Heavy biofilm, low destruction Destruction commensurate with biofilm Minimal biofilm Destruction commensurate with biofilm deposits 3 / 20 What degree of mobility indicates Stage IV complexity? ≥1 ≥2 ≥3 Any mobility Tooth mobility degree ≥2 is a Stage IV complexity factor 4 / 20 What is considered bite collapse in Stage IV? <15 teeth <22 teeth <18 teeth <20 teeth <20 remaining teeth (10 opposing pairs) indicates bite collapse in Stage IV 5 / 20 Which Stage first presents with vertical bone loss ≥3mm? Stage I Stage III Stage IV Stage II Vertical bone loss ≥3mm first appears in Stage III complexity factors 6 / 20 What is the radiographic bone loss (RBL) percentage in Stage I? >50% <15% 33-50% 15-33% 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] 7 / 20 Which grade should clinicians initially assume? Grade C No grade Grade B Grade A Clinicians should initially assume Grade B Key Points: 8 / 20 Stage III and IV share which CAL measurement? 1-2mm <1mm ≥5mm 3-4mm Both Stage III and IV show CAL ≥5mm 9 / 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 B Stage II, Grade A Stage I, Grade B PD and bone loss indicate Stage I, risk factors indicate Grade A 10 / 20 What’s the minimum criteria needed to shift to Stage IV? Vertical bone loss Furcation involvement ≥5 teeth lost RBL below middle third of the root ≥5 teeth lost automatically moves to Stage IV 11 / 20 At what location is RBL measured? Average of all sites Least affected site Most affected site Random site RBL is measured at site of greatest loss 12 / 20 Which type of bone loss is predominantly seen in Stage I and II? Horizontal Both equally Vertical Neither Stages I and II show mostly horizontal bone loss 13 / 20 What bone loss/age % indicates Grade B? >1.0 0.25 to 1.0 2 <0.25 Grade B shows moderate rate with bone loss/age ratio 0.25 to 1.0 14 / 20 What is maximum probing depth in Stage I? ≤6 mm ≤5 mm ≤3 mm ≤4 mm Stage I complexity shows maximum probing depth ≤4 mm 15 / 20 Grade C smoking modifier is defined as? ≥10 cigarettes/day Non-smoker Any smoking <10 cigarettes/day ≥10 cigarettes/day modifies to Grade C 16 / 20 In Stage II periodontitis, what is the CAL range? <1mm ≥5mm 3-4mm 1-2mm Stage II is characterized by 3-4mm interdental CAL 17 / 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. 18 / 20 Which stage first presents with furcation involvement? Stage III Stage I Stage IV Stage II Furcation Class II or III first appears in Stage III complexity 19 / 20 For extent description, what are the three possible patterns? Early/Late/Advanced Localized/Generalized/Molar-Incisor None of above Mild/Mod/Severe Extent described as localized, generalized, or molar/incisor pattern 20 / 20 What smoking status indicates Grade A? Any smoking ≥10 cigarettes/day <10 cigarettes/day Non-smoker Non-smoker status indicates Grade A 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
