What is the maximum recommended dose of 4% articaine with 1:100,000 epinephrine?

  1. 0.2 mg/kg
  2. 7 mg/kg (max 500 mg)
  3. 4.4 mg/kg (max 7 mg/kg)
  4. 0.04 mg/kg
Show answer and explanation

Correct answer: C. 4.4 mg/kg (max 7 mg/kg)

  • A. 0.2 mg/kg is not the standard articaine dosing figure.
  • B. 7 mg/kg is the absolute upper limit, not the standard recommended dose. The standard is 4.4 mg/kg.
  • C. Correct. The recommended maximum dose of articaine is 4.4 mg/kg, with an absolute maximum of 7 mg/kg or 500 mg in adults. Articaine 4% = 40 mg/mL. Always calculate based on patient weight.
  • D. 0.04 mg/kg is far below any therapeutic or toxic level for articaine and is not a correct dosing figure.
