Frequency of Barodontalgia Among Military or Civilian Pilots and Aircrew Members
2013
Dental pain triggered by a change in barometric pressure is called
barodontalgia. It can be severe enough to cause in-flight incapacitation. The incidence of in-flight
barodontalgiais varied in the literature and most of the current epidemiological data on
barodontalgiahas been compiled from military
aircrew. The aim of this study was to evaluate the frequency of
barodontalgiain French military and civilian
aircrew. A cross-sectional study was conducted in 2010. The pilots and crewmembers attending 10 medical units of the French Air Force and Navy, and 5 dedicated to civilian pilots and
aircrewwere given a standardized and anonymous questionnaire to complete regarding demographic and professional characteristics as well as their
barodontalgia. Out of the 1475 questionnaires distributed, 1184 responded, and 6.6% of these participants reported at least one event of
barodontalgiaduring their career; 43 from the air force and 31 from a civilian service. Median pain intensity during
barodontalgiawas evaluated at 5.5 out of 10. Pain appeared most commonly during descent (47.3%) and was more frequent below 8000 m. In 10 cases the
pilots reportedthat
barodontalgiacould have compromised flight security. Despite the improvement of aeronautical equipment and the quality of
dental care,
barodontalgiaswere still present in 2010 in the French military and in civilian
aircrews. The authors recommend that prevention programs be established in order to minimize the frequency of
barodontalgiasand their potential repercussions on flight safety.
