- during a procedure
- post operatively

- abcess incision
- palate for impressions

Anaesthesia achieve by diffusion of anaesthetic solution to site of action and site of operation. e.g root apex of tooth
Effectiveness determined by the permeability of the tissues (especially bone) through which the solution has to pass
What are some Infiltraton limitations?
- Thicker Bone Zygomatic Proccess
- Divergent roots
- Very dense outer cortical bone
Lidocaine will not work on lower molars whereas Articaine should
What does Regional (block) Anaesthesia do?
What are some examples of Nerves commonly blocked?
Blocks a whole nerve trunk, often at some distance from the site of operation.
