Best local anesthetic choice for routine pediatric dental procedures?

  1. Articaine 4% with vasoconstrictor
  2. Amide with vasoconstrictor (lidocaine 2% + epi 1:100,000)
  3. Amide without vasoconstrictor
  4. Bupivacaine 0.5% with vasoconstrictor
Show answer and explanation

Correct answer: B. Amide with vasoconstrictor (lidocaine 2% + epi 1:100,000)

Lidocaine 2% with epi 1:100,000 = gold standard in pediatric dentistry. Vasoconstrictor reduces systemic absorption (lowers toxicity), prolongs anesthesia, reduces bleeding. Bupivacaine avoided in children (long duration → lip/cheek biting risk).
