High altitude flying reveals dental troubles that elude even the X-ray. Naval doctors found for instance, a naval dive-bomber pilot reported that he was always troubled with severe toothache just before going into a dive. He blamed sinus trouble. But a test in a pressure chamber simulating the atmospheric conditions at high altitude revealed hidden decay that had not been detected by X-rays. Studying an undisclosed number of cases, navy doctors found:
(1) Fifty-seven per cent, of airmen developed toothache in a pressure chamber equivalent to a height’ of 28,000 feet.
(2) Twenty-three per cent, experienced pain at a reading equivalent to 18,000 feet.
(3) Twenty per cent, began showing symptoms before reaching the equivalent of 10,000 feet.
After the hidden decay had been located and repairs carried out, the airmen experienced no further discomfort.
