maxillary infiltrations are used to anaesthetise any maxillary teeth
retract lip
inject 2ml of lignocaine with adrenaline using 25G needle at the deepest part of the sulcus directly above the tooth involved with the needle penetrating 2mm deep into the tissues
infraorbital nerve block
provides dental anaesthesia from the maxillary midline to the premolar region (teeth nos 1 to 5) and all the upper lip of that side of the face.
anterior mandibular teeth
mandibular infiltrations are suitable ONLy for anaesthetising anterior mandibular teeth between the two lower canines (33 to 43).
use technique as for maxillary infiltrations
premolar and molar mandibular teeth
these are anaesthetised by using an inferior alveolar nerve block:
penetrate the apex of the buccal pad of fat with the mouth wide open ~20-25mm until you hit bone then withdraw needle 1-2mm, test for negative aspiration to exclude that you are not in a blood vessel, then inject 2mls of lignocaine with adrenaline
this will provide anaesthesia to all lower teeth in that quadrant up to the midline including half of the lower lip, chin and tongue of that side of the face.
