Dental Instruments – Syringes
Dental syringes are used to administer local anesthetic in dentistry. They are designed to deliver precise and controlled amounts of anesthetic to the targeted area.
There are two main types of dental syringes: aspirating and non-aspirating. Aspirating syringes have a feature that allows the dental professional to check whether the needle tip is in a blood vessel before injecting the anesthetic solution. This is important to avoid injecting the anesthetic into a blood vessel, which can cause complications. Non-aspirating syringes do not have this feature.
Dental syringes typically have a barrel made of plastic or metal, and a plunger that is used to push the anesthetic solution through the needle. The needle is made of stainless steel and is available in different lengths and gauges to suit different types of injections and patients.
To use a dental syringe, the dental professional first selects the appropriate needle and loads the syringe with the anesthetic solution. They then identify the target injection site and use the syringe to deliver the anesthetic to the area.
Proper cleaning and sterilization of dental syringes are important to prevent contamination and ensure patient safety. Dental professionals should follow proper infection control protocols and replace syringes and needles that become worn or damaged.
