Vasodepressor syncope, commonly known as fainting, is a frequent occurrence during stressful situations, which include the delivery of dental care. This condition is usually benign; however, if left untreated, it can be fatal. The common faint is caused by a transitory and sudden loss of consciousness following a period of cerebral ischemia. Patients usually fall to the floor or are placed in a supine position, which results in restoration of blood flow and return to consciousness. If the flow patterns to the brain are not restored, however, life-threatening cardiovascular and pulmonary effects can occur.

Dental Procedure, Needle Phobia and Fainting
Some people faint at the sight of needles. This may be common if you have what is called a blood-injury-injection phobia, where you get very anxious by seeing blood or an injury or by receiving an injection.
According to some sources, many people (70-80%) who have a blood-injury-injection phobia faint. But other studies have failed to find such a high incidence of fainting. For example, in one study by DeJongh and his colleages (1998), none of the people with blood-injury-injection phobia fainted during dental treatment. So it is unclear exactly how common fainting is.
