How is the Gingival Bleeding Index Scored?

How is the Gingival Bleeding Index Scored?

• A. 0-5 scale
• B. 0 = absence; 1 = presence (bleeding sites/ total sites times 100)
• C. 0-100 scale based on bleeding duration
• D. 0-2 scale by pocket depth

Answer: (B)

The Gingival Bleeding Index gauges gingival inflammation by checking bleeding on probing across multiple sites. For each site, you record 0 if there is no bleeding and 1 if bleeding occurs. After assessing all sites, you calculate the index by dividing the number of bleeding sites by the total number of sites and multiplying by 100, giving a percentage. This matches the description of scoring as 0 for absence and 1 for presence, with the overall score expressed as a percentage of sites that bled. The other formats—a 0-5 scale, a duration-based 0-100 scale, or a scale tied to pocket depth—do not reflect how this index is calculated.
