Several oro-facial physiologic and pathologic phenomena affect individuals during flight or self-contained underwater breathing apparatus (SCUBA) diving. Physicians and dentists who treat aircrews and divers are occasionally challenged by those manifestations, though their uncommon appearance. This article reviews the two main barometric-related phenomena in the oral cavity: dental barotrauma and barodontalgia. Dental barotrauma includes all barometric-related dental mechanical phenomena. Tooth fracture or failure of dental restoration usually appears in a tooth with a leaking restoration or secondary caries lesion. In addition, changes in barometric pressure can cause a reduction in the retention of dental restoration and appliance. Barodontalgia is the oral pain which evoked during changes of the atmospheric pressure. This manifestation can be classified as a direct or non-direct pain. In most cases, the direct pain is caused by deterioration of pre-existed oral disease, whereas the source of the nondirect pain is an extra-oral facial barotrauma. These two barometric-related manifestations can cause a decrease in life quality and jeopardize the safety of flight or diving.
