Syncope is most often caused by some form of psychogenic (psychological) or nonpsychogenic (physical) stress. Psychogenic factors (e.g., fear, pain, emotional upset, and anxiety) are the most common causes of syncope in the dental office. Common psychogenic stressors in the dental office include fear of dental treatment, sudden pain, or a poor prognosis. Nonpsychogenic factors that may contribute to syncope include hunger, poor health, and remaining in an upright position for a long period.
