Due to the progress of medicine, more and more people are extending their lives thanks to transplants, surgeries, medicines, etc. This creates more and more patients at risk who need to be treated in dentistry in conditions of maximum safety. Similarly, there are people who, for physical or psychological reasons, are unable to show themselves very collaborative during dental treatments. It is to this type of patients that dentistry tries to offer a solution through general anaesthesia, thus resolving dental problems that could otherwise not be treated.

General anaesthesia is obtained with a controlled loss of consciousness, accompanied by partial or complete loss of defensive reflexes, including the ability to independently maintaining an airway and responding to verbal commands. In dentistry this technique must be performed by an anaesthesiologist, in an operating room and in the company of the dentist.
