Anesthesia · single question

A child bit his lip after an appointment at which an inferior alveolar nerve block was given. What modification best reduces this risk at the next visit?

1. Use an inferior alveolar block with 4% articaine
2. Use plain 3% mepivacaine, and consider infiltration rather than a block where feasible
3. Use 0.5% bupivacaine with 1:200,000 epinephrine
4. Use an inferior alveolar block with 2% lidocaine with 1:100,000 epinephrine
