Which of the following is a common type of local anesthetic used in dentistry?

Lidocaine is widely recognized as a common and effective local anesthetic used in dentistry due to its rapid onset of action and relatively long duration of anesthesia. It provides profound and reliable local anesthesia, making it ideal for various dental procedures, such as fillings, extractions, and periodontics. The ease of use and favorable safety profile contribute to its popularity; it can be administered via injection or through topical forms, allowing for flexibility depending on the dental procedure and patient needs.

While other anesthetics listed, such as Procaine, Benzocaine, and Mepivacaine, are also used in dentistry, Lidocaine is the most prominently utilized due to its effectiveness and versatility in clinical practice. Procaine is less commonly used today primarily because it has a slower onset and shorter duration compared to Lidocaine. Benzocaine is primarily a topical anesthetic and not typically used for injections in dental procedures. Mepivacaine is also a local anesthetic used in dentistry, but it is not as frequently utilized as Lidocaine. Therefore, Lidocaine stands out as the go-to option for local anesthesia in dental settings.
