What is the function of a syringe in dentistry?

1. To extract teeth

2. To deliver local anesthesia

3. To clean cavities

4. To apply fluoride treatment

The correct answer is: To deliver local anesthesia

The function of a syringe in dentistry is primarily to deliver local anesthesia. In many dental procedures, it is crucial to numb a specific area to ensure the patient feels minimal discomfort. The syringe, equipped with a needle and filled with anesthetic solution, allows the dentist to administer precise amounts of anesthetic medication into the tissues surrounding the area being treated. This controlled delivery helps to manage pain effectively during procedures such as fillings, extractions, or any other invasive treatments. While extracting teeth or performing cavity cleanings may involve other tools and techniques, the syringe's primary role is in the administration of anesthesia. Similarly, fluoride treatments are usually applied using trays or varnishes rather than syringes. Therefore, the syringe is distinctly associated with the delivery of local anesthesia, making it an essential tool in ensuring patient comfort during dental procedures.
