Flashcards in exam 3 study guide Deck (33):
what anesthetizes small area of two teeth, deposited at the apex of the tooth?
Supra-periosteal, recommended when needed in localized area commonly referred to as infiltration
what's the best practices for increasing patients comfort for maxillary injections?
needle should not be moved within the tissue nor should the patients upper lip be shaken as previously discussed, topical anesthesia is used and local is deposited slowly, slightly jiggle lip and don't hit bone
which order is maxillary injection done?
back to front- PSA, MSA, ASA
how should the syringe be held?
keep to occlusal plane and 45 degree to not hit the bone especially in PSA
what practices to avoid when administering anesthetic?
not using enough, giving too much, administering a greater area than needed
what to do if needle accidentally contacts bone?
withdraw the needle, change needle, and reinsert to to decrease any further trauma
what is the supraperiosteal injection most common in?
primary molars than permanent due to decrease in bone
which of the following is the best practice for MSA?
long axis to the tooth, bevel to bone, needle placed above apex
when administering PSA, what other nerve could be numbed?
what anesthesizes a larger area?
when giving MSA, where is it in the dental arch?
half way around the mouth
when doing SRP on mandibular molars, what block would be done?
what is the most commonly used injection?
after giving IA, which injection would numb the incisors?
what is the hardest injection?
what injection is most likely to cause lingual shock due to needle close to lingual nerve?
why would a patient not get numb enough?
because it was deposited inferior to the apex and in children, dense bone covers where apex should be
what reduces discomfort on palatal injections?
where is anatomy most varied?
when administering IA, what other nerve could be numbed?
where is the pterygomandibular fold?
extends behind most distal molar and retromolar pad, runs horizontally to the posterior border of the mandible and then turns superior to the junction of hard and soft palate, separating the buccal mucosa from pharynx
this anesthetizes the mental nerve and thus the association facial periodontium, and gingiva of the mandibular anterior teeth and premolars to the midline
this anesthetizes incisive nerve and thus mandibular anterior teeth and premolars as well as association with facial periodontium and gingiva to the midline
where does PDL injection enter?
most common reaction to anesthesia?
what is not recommened for children?
what is located more inferior in children than adults?
when do most adverse reaction to drugs occur?
within five to ten minutes of injection
what does LAST manifest as?
excitation followed depression of the CNS system and to lesser exten of CVS
local anesthetic systemic toxicity
this is factored into MRD?
what should be avoided with children?
trigger words like shot, needle, hurt, pain or bee sting
