Q

what does infiltration anaesthesia act on?

A

nerve endings

Q

what does infiltration require in order to work?

A

has to diffuse through the bone to root apex

Q

what tooth is difficult to anaesthetise using infiltration?

A

upper 1st molar as thicker bone due to buttress system

Q

steps for maxillary infiltration

A

dry site

topical anaesthesia gel on cotton wool, 3-5 mins

retract tissue, taught

insert needle, bevel facing bone, syringe at 45 degrees to bone

insert till touch bone, withdraw 1mm

aspirate

1ml solution per minute

Q

regional (block) anaesthesia acts on what?

A

nerve trunk

Q

regional block anaesthesia is used to block what nerves in the maxilla?

A

incisive branch of nasopalatine nerve

greater palatine nerve

Q

where should you aim for a regional block of incisive branch of nasopalatine nerve?

A

between central anteriors in line with canines

Q

where should you aim for a regional block of greater palatine nerve?

A

between the 7 and 8 about 1cm away from gingival margins

Q

what is aspiration?

A

technique to reduce the risk of IV injection by creating negative pressure at the tip fo the needle so you pull up a sample of the injection site -> if blood then likely its in a vessel

Q

what size needle should you use?

A

short
25mm
30gauge
