A history of words

The word ''orthodontics''. In 1841, Lefoulon suggested the term ''orthodontosie,'' which the Americans simplified to ''orthodontia'' and, later, to ''orthodontics''. But the French resisted. A long struggle began between ''orthopedics'' and ''orthodontics,'' which wound up in 2007 with ''orthognathodontics.'' Have we reached a truce? 2 - The word ''malocclusion''. E. Angle decided that the word ''irregularity'' employed in the 19 th century was inappropriate. He proposed the term ''malocclusion'', which the French for a long time denigrated only to begin to employ it recently. But beneath new vocables new concepts are hidden.
