The 'interdental plate' refers to the bone-filled mesial-distal region between the teeth.^[1] The word "''interdental''" is a combination of "''inter''" + "''dental''" (meaning "''between the teeth''") originiated in approximately 1870.^[2] In paleobiology, the presence or absence of the interdental plate can determine the place of an animal in the evolutionary scale and paleontologists use the interdental plate when trying to classify a new specimen. Thecodont reptiles and theropod dinosaur fossils have an interdental plate, whereas acrodont reptiles such as ''Sphenodontia'' do not.^[3] Its presence in ''Archaeopteryx'', an extinct avian, resulted the proposal of the dinosaur-bird connection.
The term can also be used to refer to a manufactured object designed to be placed or worn between the teeth. An example would be a dental prosthetic designed to prevent contact between the teeth while the wearer is sleeping.^[4] relates to an apparatus designed to measure the pressure exerted by the tongue as a means of diagnosing ailments related to swallowing.^[5]
