Could you explain how each local anesthetic solution is used in Dentistry?

I am a new dental assistant and if a dentist, hygienist or assistant could explain the different local anesthetics used and when used when numbing someone, that would be wonderful! Also, what gauge of needles are used for injections? Thank you.

ask the people you work for!
Reply:DUDE, you're looking for a dentist on yahoo answers?


Any dentist you find here is either not a good one (they're here instead of with patients), or is most likely nuts. You'll get people who are dentists, sure.. only problem is, only in their own minds!
Reply:They block both the initiation and conduction of nerve impulses by decreasing ionic flux through the neuronal membrane.





Basically, they shut down the pump in the nerve ending that stimulates the sensation and transmission of pain.
Reply:Sounds more like you are trying to practice dentistry without a license. If you are really a dental assistant, you won't need to do any of these things, nor would you need to know this information. If you really think you need it, ask the people you work for.
Reply:There are a variety of anesthetics, and every office you work for will have their own favorites. Generally, you avoid vasoconstrictors for patients with a cardiac history or hypertension.


Dentists have different ideas about needle guage too--they told us you needed a 25 ga. needle to aspirate, but that's just not true. I use 27 and 30 ga. needles--but you'll use what the dentist you work for likes.

all doctors use different supplies... three doctors at our clinic and two use 30 gauge short, and one uses 27 gauge long..


and also 30 gauge x-short when using a ligmaject
