Which ester local anesthetic is mainly used in dentistry today?

Lidocaine
Bupivacaine
Articaine
Mepivacaine

The correct answer is: Articaine

Articaine is the main ester local anesthetic used in dentistry today. Lidocaine, bupivacaine, and mepivacaine are all amide local anesthetics, which are similar in structure and function but are metabolized differently in the body. Articaine has a faster onset and shorter duration of action compared to other ester local anesthetics, making it a popular choice for dental procedures. While lidocaine is one of the most commonly used local anesthetics in dentistry, it is actually an amide, not an ester. Likewise, bupivacaine and mepivacaine are also amides and are not the primary choice for dental anesthesia.
