Correct answer: D — Hamp classification (Grade I, II, III)
The Hamp classification (Grade I, II, III, with optional Grade 0) is the internationally recognised and UK-adopted standard for grading furcation involvement based on the horizontal extent of periodontal breakdown in multi-rooted teeth. Distractors fail because: BPE is a screening tool for bleeding and pocket depth, not furcation-specific; TNM is an oncology staging system; Angle classification addresses dental malocclusion; Ramfjord index is an alternative measurement using a different (2 mm) threshold, not the primary classification system for horizontal extent. UK SDCEP guidance explicitly uses Hamp Grade I/II/III terminology in clinical recommendations for management. This is an Easy-level recall item testing core periodontal knowledge.
