Attitudes of a group of Brazilian orthodontists towards the diagnosis and management of primary headache (migraine): an electronic-based survey

OBJECTIVES: The aim of this study was to investigate the knowledge and attitudes of orthodontists in the diagnosis and management of migraine without aura. MATERIAL AND METHODS: Participants were dentists, recruited among members of the Brazilian Association of Orthodontics and Facial Orthopedics (ABOR). An e-mail was sent to all ABOR members, with a link to a website, especially prepared for this research. Dentists were presented to a report of a fictional patient fulfilling diagnostic criteria for a primary headache disorder, known as migraine without aura. Participants were asked to describe how they would relieve the patient's pain. Professional procedures were classified as "adequate" or "inadequate" according to the answers given. RESULTS: 161 valid answers were received (18.8% response rate). Of them, 36% of the actions were considered to be "adequate" procedures, while 64% were "inadequate". The results yielded 12 main procedures, based on common characteristics. Eighty-two orthodontists suggested orthodontic treatment with or without orthognathic surgery, and some suggested using stabilization appliances prior to the orthodontic treatment. CONCLUSIONS: The majority of participants proposed inadequate therapies, and 51% suggested orthodontic correction of occlusion, including orthognathic surgery. Educational activities on migraine should also target orthodontists.
