Maximum dose of local anesthetics in dentistry

The U.S. Food and Drug Administration (FDA) has reviewed and established new dosage guidelines for local anesthetics in dentistry. There are several changes compared to previous guidelines.

One significant difference is that for adults, the maximum dose of articaine is now determined strictly by the patient's weight.
