1. Toothache experienced at lowered atmospheric pressures, as in aircraft flight or in a decompression chamber, caused by the expansion of air in the maxillary sinuses.
2. Dental pain caused by either increased or reduced atmospheric pressure; also aero-odontalgia.

The science of the effect of either increased or reduced atmospheric pressure on the teeth.

1. That branch of dentistry which is concerned with effects on the teeth of those who are flying at high altitudes.
2. A branch of dentistry concerned with the prevention and treatment of aerodontalgia.

The study of the effects of high-altitude flying on the teeth.

Another term for aerodontalgia.

Aerodontalgia or toothaches associated with the reduction in atmospheric pressure in high-altitude flying.

The difference in pressure exacerbates existing pulpitis, particularly in connection with caries and restorations.

Having differentiated or unequal teeth; heterodont.

A congenital absence of the teeth other than by extraction or impaction.

This nomenclature, meaning “toothless lizard” is no longer recognized by scientists because they found that it described an animal that was previously given another name which is Euoplocephalus aucutosquameus. Named by Charles Hazelus Sternberg (1850-1943) in 1929.

Toothache associated with the reduction in atmospheric pressure in high-altitude flying. Also: aerodontalgia.

Having bad or malformed teeth.

“Carcharodon (or shark-toothed) lizard” from Late Cretaceous period and found in what is now known as the Sahara Desert (southeastern Morocco in 1995). This lizard was named for the Greek (karkharodon, “jagged toothed”) Carcharodon, the great white shark. Named by German paleontologist Ernst Stromer von Reichenbach in 1931.
