Cluster headache is a neurovascular disorder characterized by attacks of severe and strictly unilateral pain presenting in and around the orbit and temporal area. Attacks occur in series lasting for weeks or months separated by remission periods. An individual attack lasts 15-180 min with a frequency of once every other day to as often as 8 times per day. Ipsilateral radiation of the headache to orofacial regions, including the teeth, is not unusual. The area of involvement may obscure the diagnosis and lead to irreversible and unnecessary dental treatment. A case in which cluster attacks occurred immediately after a dental procedure is described. (J Oral Sci 53, 125-127, 2011)
