Pressure

A ____________ syringe is primarily used for PDL injections of single mandibular teeth where tissue resistance is pronounced

Achieves the negative pressure necessary for an aspiration without a harpoon

Withdraw the needle completely, change the direction of the needle, penetrate, and readvanch to the target location.

After arriving at the deposition site, you decide to redirect your needle to achieve effective anesthesia. Which of the following is an appropriate action?

Using fingers to recap the needle when he needle has not entered the patient's mouth

All are the acceptable way to recap a needle EXCEPT one.

Buffered anesthetic

All the following cause a burning sensation when the anesthetic is injected into just tissue EXCEPT one.

Using a 25-gauge needle

All the ways that increase the risk of needle breakage EXCEPT one.

Recap the needle with the one-hand scoop method, discard it and replace it with a new, sterilized needle. Proceed in administering the local anesthesia

As you are about to administer an injection, your needle tip inadvertently touches the patients's disposable bib (clean but not sterile). What should you do?

Cartridge-penetrating end

Expensive

Disadvantages for the wand?

The diameter of the needle

Gauge

Pressure anesthesia

Gauze 2x2 squares are a helpful supplement to the anesthetic armamentarium. Which of the following is NOT a function of a gauze 2x2?

Excessive pull during aspiration and failure to properly engage the harpoon during setup

Harpoon disengagement may occur due to which operator error?

Recapping using the scoop method and disposal in an approved sharps container

How should a clinician properly dispose of anesthetic needles?

Remove the syringe from the patient's mouth, remove the needle, and reengage the harpoon into the rubber stopper

If the harpoon disengages during an aspiration, the clinician should?

Used for topical anesthetic of soft tissue, delivers via pressure, no needle, and in costly

Jet injector syringe

Greater accuracy and increased injection success

Larger needles have what advantages over the smaller gauge needles?

The hallow portion of the needle

Lumen

The size tubular (channel) of the needle is related to the gauge

Lumen

Made of plastic or metal and provides a means to attach the needle to the syringe

The hub and syringe adaptor

Treaded needle attachment

Needle adaptor (hub)

Protects the needle that is inserted in the tissue, as well as the cartridge-penetrating end of the needle

Needle sheilds

Used for PDL or intraligamentry injections

Pressure type syringe

Negative pressure

Pulling back on the thumb ring provides _______ and produces an aspiration

25 gauge

Recommended for highly vascular areas and risks of positive aspiration

Inspection and replacement of the finger ring Lubrication of the piston Inspection and replacement of a dull or bent harpoon

Routine maintenance of a reusable syringe includes?

Harpoon

The ___________ is a sharp tip attached to the internal end of the piston that embeds into the cartridge's rubber stopper

Breech loading allows or side loading of cartridge through window

Syringe barrel

The syringe must be disposable

The ADA has set forth criteria for the acceptance of local anesthetic syringes. Which of the following is NOT consistent with the ADA's standards?

ASMA

The Wand (CCLAD) is best used for this block

The angled surface of the needle tip that is directed into the tissue to provide a cutting surface that offers little resistance to mucosa as the needle penetrated and withdraws from the tissue

The bevel

Be turned toward the bone

The bevel of the needle should

Anesthetic drug inside the cartridge

The color-coded band on the anesthetic cartridges identifies what?

Reusable breech-loading metallic cartridge-type aspirating syringe
