In flight barodontalgia and the differential diagnosis of odontogenic pain: a case report

Introduction: The barodontalgia is an acute condition due to the air pressure difference that affects the health and the well being of pilots during flight. Military pilots are more susceptible to pressure differences due to quick maneuvering, the extreme situations in flight, or due the lack of pressure into aircraft cabin. Such occurrence can lead to dizziness and premature end of the flight. Its origin may be in the tooth, related to some pre-existing condition or not, and also in other structures of the face, especially in the maxillary sinus. Of the cases reported, 70% came from pulpitis related to deep restorations, and most cases (81%) appeared in the aircraft taking off. Aim: To report a clinical case of a T-29 Brazilian Air Force pilot, who came to Santos-Dumont Air Force Dental Clinic, immediately after landing. The patient interview pointed out barodontalgia as a cause of his acute toothache. After the diagnosis of necrotic pulp, the tooth was endodontically treated in single session by using the Protaper Universal rotary system, and filling with Hybrid Tagger thermoplasticized technique. In the query of reevaluation, the patient reported no further episodes of dental pain in flight. Conclusion: It is evident the relevance of knowledge of this condition by military and civilian dentists, to conduct proper diagnosis and treatment of airmen.
