A box of 'Pensacaine' lignocaine hydrochloride local anaesthetic injection cartridges, manufactured by S S White Ltd, England. The use of local anaesthetics in dentistry effectively dates back to the discovery of Novocaine early in the 20th century. Today it is rarely used, having been superseded by more powerful anaesthetics, particularly lignocaine hydrochloride. Lignocaine is a local anaesthetic commonly used in dentistry and often combined with 2% adrenaline to prolong the anaesthetic effect reducing the blood flow.
