Which pair of indices includes gingival inflammation and sulcus bleeding?

• A. OHI-S and Gingival Bleeding Index
• B. Gingival Index and Sulcus Bleeding Index
• C. Gingival Index and OHI-S
• D. Plaque Index and OHI-S

Answer: (B)

Gingival inflammation is assessed by the Gingival Index, which grades the gingiva based on color, edema, and bleeding on probing. The Sulcus Bleeding Index specifically measures bleeding from the gingival sulcus after probing, reflecting bleeding tendency in the sulcus itself. Since the question asks for a pair that includes both gingival inflammation and sulcus bleeding, this combination is the best fit because it separately covers both phenomena: inflammation of the gingiva and the sulcus bleeding response. The other pairings mix in general hygiene/plaque measures or bleeding indices that don’t specifically target sulcus bleeding, so they don’t meet the requirement of addressing sulcus bleeding alongside gingival inflammation.
