WAND is technological equipment which is used to inject controlled amount of local anaesthesia. It is computer controlled and the device regulates the flow of the anaesthesia in the injection. This can reduce pain and anxiety in patients. It is an advanced dental machine which has made the delivery of local anaesthesia simpler and more precise. Most patients report pain caused from injection when administering local anaesthesia. This pain is essentially caused by the quick in flow of the anaesthetic. WAND slows down the flow of numbing agent and hence solves the problem.
