Barodontalgia, barometric pressure-induced dental pain, may jeopardize diving/flight safety. The aim of this systematic review was to investigate the rate of barodontalgia among military and civilian divers and aircrews based on previous reports. We analyzed the data of 4894 aircrew/divers reported in the literature. Barodontalgia rates (flight vs. diving, military vs. civilian, pressurized vs. non-pressurized aircrafts) were analyzed. The Chi-squared test was used to compare between groups. Of the 4894 individuals, 402 (8.2%) suffered from barodontalgia. Divers (9.8%) were more vulnerable than aircrews (5.8%). Barodontalgia experience rate was 5.4% and 6.5% in military and civilian aircrews, respectively, and 7.3% and 12.8% in military and civilian scuba divers, respectively. Barodontalgia was more common among aircrews of pressurized than non-pressurized aircrafts (7.3% vs. 3.2%, respectively). The greater amplitude of barometric pressure changes explains the higher rate of barodontalgia in divers than aircrew. The higher rate during pressurized flights is possibly because intracabin pressure in the pressurized cabin is still routinely higher than in nonpressurized aircrafts. Improved oral care and mandatory annual dental checkups may be the reason for the significantly lower rate of barodontalgia experienced among military aircrews and divers compared to their civilian counterparts. These results emphasize the essential role of atmospheric pressure change in the generation of pain during flight or diving and the importance of proper dental care.
气压性牙痛，即由气压变化引起的牙痛，可能会危及潜水/飞行安全。本系统评价的目的是根据既往报告调查军事和民用潜水员及机组人员中气压性牙痛的发生率。我们分析了文献中报道的4894名机组人员/潜水员的数据。分析了气压性牙痛发生率（飞行与潜水、军事与民用、增压飞机与非增压飞机）。采用卡方检验进行组间比较。在这4894名个体中，402人（8.2%）患有气压性牙痛。潜水员（9.8%）比机组人员（5.8%）更容易患病。军事和民用机组人员的气压性牙痛发生率分别为5.4%和6.5%，军事和民用水肺潜水员的发生率分别为7.3%和12.8%。增压飞机的机组人员中气压性牙痛比非增压飞机更为常见（分别为7.3%和3.2%）。气压变化幅度更大解释了潜水员中气压性牙痛发生率高于机组人员的原因。增压飞行期间发生率较高可能是因为增压舱内的舱内压力通常仍高于非增压飞机。与民用同行相比，军事机组人员和潜水员中气压性牙痛发生率显著较低的原因可能是口腔护理的改善和每年强制进行牙科检查。这些结果强调了大气压力变化在飞行或潜水期间疼痛产生中的重要作用以及适当口腔护理的重要性。
