最早在第二次世界大战时有航空牙痛(Aerodontalgia)一词,最近认为用气压性牙痛(Barodontalgia)更为恰当。1944年美国海军对920个作过汞合金修复者作了研究,当模拟30,000呎高度时,无一疼痛。在另一研究中,故意封闭气体于修复物与牙髓壁之间,发现气体膨胀与牙痛无关。从而认为高空中的牙痛,主要和龋与牙髓的接近程度有关,而高度的变化比高度 Earlier in World War II, there was the term Aerodontalgia, which has recently been considered to be more appropriate with Barodontalgia.
