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.

 
Predisposing factors that can lead to syncope include fright, pain, emotional stress, anxiety, hunger, sudden postural changes, and exhaustion. Identifying these predisposing conditions and treating them can often prevent an episode of syncope.
