Advancements in Local Anaesthesia- A Review
Keywords:: Dental anesthesia, local anesthesia delivery device, computer controlled anesthesia, vibratory stimulation
Intra oral local anesthesia is perceived as a painful and an anxiety causing dental procedure. Most of the
researches are focused on improvement in the area of anesthetic agents, delivery devices and technique
involved. Newer technologies have been developed to reduce the pain of injection and adverse effects.
These include buffering the local anesthetic, warming the local anesthetic, applying topical anesthesia
before injection, reducing speed of injection using finer needles with electric delivery devices. Sterile
local anesthesia should be used and effort should be made to reduce the speed of injection. This article will
discuss in detail about the various advanced techniques of local anesthesia.
