這題就是考官把課本的一句話拿出來跟你說BOP就是indicator課本說有BOP = good indicator of progressive attachment loss你會問: (B)選項呢!!(B) 探測囊袋深度增加（PPD）　　This is important when evaluating differences in probing depth before and after treatment, because the reduction in probe penetration may be a result of reduced inlammatory response rather than a gain in attachment.→ 不好意思，PPD減少可能是發炎反應減少的結果，而非Attachment增加　　Probing depth may change from time to time, even in patients with untreated periodontal disease, as a result of changes in the position of the gingival margin. Therefore it may be unrelated to the existing attachment of the tooth.→ 不好意思，PPD可能跟attachment沒關係
