dental anaesthesia

maxillary teeth

maxillary infiltration

  • 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.
