Question

Quizplus · Accepted Answer

3% mepivacaine plain is a better drug choice than 2% lidocaine when vasoconstrictor is contraindicated because it is a weak vasodilator, not because it has higher drug content. It provides 20 to 40 minutes pulpal anesthesia compared to 2% lidocaine which provides 5 to 10 minutes of pulpal anesthesia without a vasoconstrictor.
