Diastema. an excessive interval or space between teeth in mammals, usually caused by reduction of part of the teeth. In most herbivorous animals the cuspids and sometimes the incisors are reduced. Similar diastemata occur in the upper and lower jaws of rodents, horses, kangaroos, and other animals. In ruminants, diastema occurs only in the lower jaw. In carnivores it takes place without reduction of teeth.
