During a Basic Periodontal Examination of an adult patient, the WHO probe's black band enters the periodontal pocket at the deepest site in one sextant but remains partially visible. Bleeding on probing and subgingival calculus are also present, with no furcation involvement. Which BPE code should be recorded for this sextant?

Correct answer: B — 3

The correct answer is B, code 3. A partially visible black band on the WHO BPE probe indicates a probing depth of at least 4 mm but not sufficient to obscure the band completely. Each sextant receives its highest applicable code, so the pocket finding takes precedence over bleeding and calculus. Code 4 would require the black band to be no longer visible, indicating a probing depth of at least 6 mm. Code 2 applies when calculus or another plaque-retentive factor is present but the band remains completely visible. Code 1 represents bleeding with the band completely visible and without calculus, while code 0 requires no significant pocketing, bleeding or calculus. No asterisk is added because there is no furcation involvement.
