title: Barodontalgia among flyers: a review of seven cases.
abstract: Once referred to as "flyer's toothache," barodontalgia is defined as tooth pain occurring with changes in ambient pressure. It usually occurs in people who fly or dive. It can develop in conjunction with sinusitis, and in teeth experiencing pulpitis after restorative treatment, new and recurrent caries, intra-treatment endodontic symptoms, dental and periodontal cysts, or abscesses. Although the causal process of barodontalgia is not well understood, it may be related to pulpal hyperemia, or to gases that are trapped in the teeth following incomplete root canal treatment. Patients who are frequently exposed to changes in ambient pressure should be encouraged to follow good oral health practices, attend regularly-scheduled dental recall examinations and accept the timely completion of restorative treatment to minimize the possibility of developing barodontalgia. By employing a classification system to document cases of barodontalgia, dentists will be better prepared to provide appropriate and successful treatment. Seven case reports of barodontalgia are presented and compared to previously documented cases. The author also reviews the reasons why military flyers are more likely to develop barodontalgia than others, although the passengers and crews of commercial airliners may also suffer from this condition.
