This selection of local anaesthetics includes a bottle of two percent Xylocaine (lignocaine hydrochloride) solution, with box produced by Astra-Hewlett Ltd of Watford and a box of two percent Xylocaine and adrenaline local anaesthetic injection cartridges by Astra Chemicals of Watford. 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 Today it is rarely used, having been superseded by more powerful anaesthetics, particularly lignocaine hydrochloride.
