What is "diastema"

Diastema \Di`a*ste"ma\, n. [L. See Diastem.] (Anat.) A vacant space, or gap, esp. between teeth in a jaw.

n. 1 A gap or space between two adjacent teeth, especially the upper front incisors (in humans). In other species, a diastema refers to a gap between teeth of different types, e.g. incisors and molars, which is a feature of some rodents and ungulates. 2 In pathology, a diastema may refer to any abnormal space, fissure, or cleft in an organ or part of the body. 3 In cell biology, the diastema is the modified protoplasm at the equator of a cell, existing before mitotic division.

A diastema (plural diastemata) is a space or gap between two teeth. Many species of mammals have diastemata as a normal feature, most commonly between the incisors and molars. Diastemata are common for children and can exist in adult teeth as well. Diastemata are primarily caused by imbalance in the relationship between the jaw and the size of teeth. If the labial frenulum (lip tissue) pulls, it can also push the teeth apart and cause a diastema between the center of the two front teeth.

A diastema is a gap between two adjacent teeth.
