Three types of syringes commonly used by dentisit

1.Common disposable syringes

The color of the needle represents different diameters, that is, different thicknesses. The orange one commonly used in the oral cavity is relatively thin, and the diameter of the needle is about 0.5mm.

This kind of syringe is often used to extract lidocaine for nerve block anesthesia. This anesthesia method can be used during tooth extraction and root canal treatment.

Although the needle is very thin, I personally still think it is thick. It is generally only used to extract saline, sodium hypochlorite, hydrogen peroxide, etc. for root canal irrigation. It is also used when anesthetizing impacted wisdom teeth.

2.Metal syringe equipped with special needles

This kind of injection is the metal syringe mentioned in the question.

The reason why it is designed in this shape is that the metal barrel is equivalent to a gun, and the bullet (anesthetic: Bilanma or Skanduni) has a special shape.

During anesthesia, instead of drawing the anesthetic from an ampoule like a disposable syringe, the entire anesthetic is put into the syringe like a bullet.

Used with a special needle, the usual dose of blue blue is 1.7ml, and the disposable syringe commonly used in the oral cavity is 5ml.

The special needles equipped with metal syringe generally have a diameter of 0.25-0.3mm, which is much smaller than ordinary disposable syringe.

Therefore, in addition to looking tougher in material, metal syringe are much more comfortable to use than disposable syringe.

The anesthesia effect of blueline and scanduni used with metal syringe is better than lidocaine in dental treatment.

Therefore, in oral treatment (especially root canal treatment and simple tooth extraction), the anesthetic effect produced by using a

metal syringe is better than using an ordinary disposable syringe.
