Local anesthesia is any technique to render a specific area insensitive to pain without loss of consciousness. This technique was first performed in the oral cavity in 1884 using cocaine. However, a number of adverse effects were observed with its clinical use.
Over the years, local anesthetics were developed to reach a high level of efficacy and safety. Techniques of administration had been improved to achieve profound anesthesia based on the understanding of the sensory innervation to the maxilla and mandible.
