Advancements In Local Anaesthesia- A Review

Abstract

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^[1]. Sterile local anesthesia should be used and effort should be made to reduce the speed of injection^[2]. This article will discuss in detail about the various advanced techniques of local anesthesia.
