In the Sulcus Bleeding Index, SBI score 1 corresponds to which finding?

• A. Spontaneous bleeding
• B. Change in color
• C. Obvious swelling
• D. Apparent healthy gingiva; BOP

Answer: (D)

Bleeding on probing with otherwise healthy-appearing gingiva indicates a mild inflammatory response detected by the Sulcus Bleeding Index. This index uses the tissue’s bleeding reaction to gentle probing to gauge gingival inflammation. When the gingiva looks normal but bleeds at the sulcus, it signals early gingivitis that hasn’t yet produced color change or swelling. The other signs—spontaneous bleeding, color change, or obvious swelling—reflect more advanced or different aspects of inflammation and would not correspond to this minimal bleeding pattern.
