Task: Answer Verification
Input (English): Question: Does cyclooxygenase-2 induction after oral surgery entirely account for analgesia after selective blockade of cyclooxygenase 2 in the preoperative period?
Answer: This study indicates that preoperative administration of a selective cyclooxygenase-2 inhibitor ensures effective control of postoperative pain. It is suggested that the selective blockade of inducible cyclooxygenase 2 at the surgical site does not entirely account for the analgesic action occurring in the postoperative period.
Output (English): no
