After Actisite tetracycline fiber is packed into a periodontal pocket, which statement is true?

When considering the placement of Actisite tetracycline fibers in a periodontal pocket, it's essential to understand the mechanism and effect of this treatment. Actisite contains tetracycline, an antibiotic that is effective in reducing the bacterial load in the periodontal pocket and thus helps in managing periodontal disease.

The first statement likely acknowledges the effectiveness of tetracycline fibers in controlling periodontal bacteria and promoting healing within the pocket. This is true because the localized delivery of the antibiotic reduces the risk of systemic side effects while targeting the specific site of infection.

The second statement might provide some information about the fiber's properties or its retention time in the pocket. If this statement incorrectly suggests that the fibers do not provide prolonged antibacterial action or that they are not retained effectively, then that would make it false.

Since the first statement is accurate regarding the therapeutic effects of Actisite, and the second statement is inaccurate regarding either the action or retention of the fibers, the conclusion that the first statement is true while the second is false is indeed appropriate. This reasoning reflects the clinical understanding of how localized antibiotic therapies function in periodontal treatment.
