Which systemic condition, when present during periodontal evaluation, is classified as a Grade C modifier in the 2017 classification regardless of bone loss pattern?
Answer: HIV/AIDS with CD4 count below 200 cells/mm³
HIV/AIDS with CD4 <200 cells/mm³ is an established Grade C modifier due to severely compromised immunity leading to rapid periodontal destruction.
A periodontal evaluation reveals a 6 mm pocket at tooth #3 with Class III furcation involvement, probing depths of 7–8 mm at multiple sites, and masticatory dysfunction. Under the 2017 AAP classification, what is the minimum Stage for this patient?
Answer: Stage IV
Masticatory dysfunction and Class III furcation on a tooth with severe pocket depths and bite collapse are complexity factors that define Stage IV periodontitis.
During evaluation of a peri-implant site, which probing finding is most indicative of active peri-implantitis rather than peri-implant mucositis?
Answer: Suppuration with probing depth of 7 mm and radiographic bone loss
Peri-implantitis is diagnosed by bleeding/suppuration on probing combined with radiographic bone loss beyond initial remodeling, distinguishing it from mucositis.
What does a periodontal risk assessment (PRA) according to the Vector model by Lang and Tonetti primarily calculate?
Answer: The individual patient's risk level for disease progression based on six parameters
The PRA Vector model assesses six risk indicators (BOP, residual pockets, tooth loss, bone loss/age, systemic factors, environmental factors) to classify patients as low, moderate, or high risk.
When evaluating a patient with generalized Stage III Grade C periodontitis who smokes 20 cigarettes/day, which adjunctive finding would most likely change the treatment plan compared to a non-smoker?
Answer: Reduced bleeding on probing despite active disease
Smoking suppresses gingival vascularity and immune response, masking bleeding on probing and underrepresenting disease severity during evaluation.
During treatment planning after a comprehensive periodontal evaluation, which scenario would most justify assigning a 'questionable' prognosis to a tooth?
Answer: Class II furcation on a maxillary molar with 50% bone loss
Class II furcation involvement combined with 50% bone loss significantly limits maintenance access and long-term survival, justifying a questionable prognosis.
A patient's chart from 3 years ago shows probing depths of 4–5 mm; current evaluation shows 7–8 mm depths. Annual bone loss rate calculated from radiographs is 3 mm over 3 years. Which Grade does this rate most support?
Answer: Grade C (rapid progression)
Bone loss >1 mm per year (in this case ~1 mm/year) meets the threshold for Grade C (rapid progression), defined as ≥2 mm bone loss per year or loss >1 mm/year in some interpretations.
