A diastema (pl.: diastemata, from Greek διάστημα, 'space') 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. More colloquially, the condition may be referred to as gap teeth or tooth gap.
In children, tongue thrusting is common due to immature oral behavior, narrow dental arch, prolonged upper respiratory tract infections, spaces between the teeth (diastema), muscle weakness, malocclusion, abnormal sucking habits, and open mouth posture due to structural abnormalities of genetic origin.
Precanine teeth are often replaced by a large diastema in therapsids. [5] [10] Kenomagnathus had both precanine teeth and a diastema, which fills the gap between basal synapsids and therapsids to some extent. It reflects what would have been an ongoing transition, which other stem-mammals with diastemata would also have gone through.
General patterns of dental morphological evolution throughout human evolution include a reduction in facial prognathism, the presence of a Y5 cusp pattern, the formation of a parabolic palate and the loss of the diastema. Human teeth are made of dentin and are covered by enamel in the areas that are exposed. [2]
Diastema – Space between upper front two teeth; Fenestration of buccal bone [13] Compression of periodontal ligament near posterior teeth; Extrusion of posterior teeth; Increased lingual bone thickness, decreased buccal bone thickness [13] One of the limits of expansion is the zygomatic buttress. It is known that this anatomical bony complex ...
Murids have sciurognathous jaws (an ancestral character in rodents) and a diastema is present. [4] Murids lack canines and premolars. Generally, three molars (though sometimes only one or two) are found, and the nature of the molars varies by genus and feeding habit.
Radial hypoplasia-triphalangeal thumbs-hypospadias-maxillary diastema syndrome Schmitt Gillenwater Kelly syndrome has an autosomal dominant pattern of inheritance . Schmitt Gillenwater Kelly syndrome is a rare autosomal dominant [ 1 ] congenital disorder consisting of radial hypoplasia , triphalangeal thumbs , hypospadias , and maxillary diastema .
The lower incisors, of which there were three on each side, [4] are procumbent (protruding), spatulate, and were separated from the cheek teeth by a long diastema. [29] The first upper molar is very enlarged, the second is one-fifth longer, and the third is only slightly larger.
