Which device is used to provide local anesthesia during dental procedures?

The anesthetic syringe is specifically designed for the purpose of delivering local anesthesia during dental procedures. This device allows the dental professional to accurately administer anesthetic agents directly into the tissue, providing numbness to the area being treated. By using a syringe, the practitioner can effectively control the dosage and placement of the anesthesia, ensuring that the patient remains comfortable throughout the procedure.

In contrast, the other devices mentioned serve different functions. A dental drill is used for cutting or removing hard tissues such as enamel or dentin but does not provide anesthesia. A scalpel is a surgical tool designed for incisions in soft tissue and is not related to anesthetic delivery. An excavator is used to remove carious material from a tooth but is not equipped to administer anesthesia. Thus, the anesthetic syringe is integral to achieving the goal of pain management in dental care, making it the correct answer.
