Which local anesthetic is commonly preferred for shorter dental procedures?

Lidocaine is commonly preferred for shorter dental procedures due to its rapid onset of action and moderate duration of effect. It typically provides adequate anesthesia for approximately one to two hours, making it ideal for procedures such as simple extractions or restorative work.

One of the primary reasons for choosing lidocaine in this context is its favorable pharmacokinetic profile. It acts quickly, allowing dental professionals to begin treatment without a significant wait time for the anesthetic to take effect. Additionally, its duration is well-suited for brief procedures, ensuring that patients remain comfortable throughout the treatment without extended numbness afterward.

In contrast, bupivacaine, while providing longer-lasting anesthesia, is generally reserved for more extensive or painful procedures due to its longer duration of action, which can extend to several hours. Prilocaine, although it also has a shorter duration, is often selected for specific cases and is known for its use in particular techniques like the Viaflo technique for infiltration anesthesia. Mepivacaine has a slightly shorter duration than bupivacaine but can also provide effective anesthesia. However, its preference for shorter procedures is not as established as that of lidocaine.

Thus, the characteristics of lidocaine make it the standard choice for brief
