What stage of development does taurodontism occur in?

In individuals with dentine dysplasia a differential diagnosis of taurodontism may arise at the early stage of dentinogenesis, since the pulp chambers may be large and resemble those which characterizes taurodontism.

When does taurodontism occur?

Taurodontism is a disorder of tooth development and occurs most commonly in permanent molar teeth. It refers to an elongation of the pulp chamber of the tooth, which can cause the tooth to lie deep in the jaw (aveolar process).

How does taurodontism occur?

The etiology of taurodontism is unclear, but it also appears in certain genetic syndromes. It is thought to be caused by the failure of Hertwig's epithelial root sheath diaphragm to invaginate at the proper horizontal level, resulting in a tooth with normal dentin, short roots, elongated body, and enlarged pulp.

What is taurodontism associated with?

Taurodontism is also associated with several developmental syndromes, including Down syndrome, Klinefelter syndrome, Mohr syndrome, Wolf-Hirschhorn syndrome, and Lowe syndrome.

What is a taurodontism?

Taurodontism is a developmental disturbance of a tooth in which body is enlarged at the expense of the roots. An enlarged pulp chamber, apical displacement of the pulpal floor and lack of constriction at the cementoenamel junction are the characteristic features.

taurodontism - developmental disturbances of teeth (part 5)

What is taurodontism anthropology?

Taurodontism is defined as the enlargement of pulp chambers with the furcation area being displaced toward the apex of the root.

Did Neanderthals have taurodontism?

Neanderthals are known to exhibit unique incisor morphology as well as enlarged pulp chambers in postcanine teeth (taurodontism). Recent studies suggest that their overall dental pattern (i.e., in morphologic trait frequencies) is also unique.

What causes dilaceration?

The possible causes for dilaceration of a permanent tooth are traumatic dental injury to the primary predecessor, idiopathic developmental disturbance, a retained or ankylosed primary tooth, and the presence of supernumerary tooth or teeth.

What causes Abfraction of the tooth structure?

Abfraction is caused by stress and pressure applied to the teeth through biting, chewing, clenching the teeth, and most commonly, teeth grinding. These forces put great stress on the teeth near the gum line, where the enamel and cementum of the teeth meet.

What is Dentinogenesis imperfecta?

Dentinogenesis imperfecta is a disorder of tooth development. This condition causes the teeth to be discolored (most often a blue-gray or yellow-brown color) and translucent.

What does the bull mean in dentistry?

An acronym for "Buccal of Upper, Lingual of Lower". A method for adjusting occlusion described by Dr. Clyde H. Schuyler where the adjustment is made to the inclined planes of the upper buccal cusps and the lower lingual cusps in order to preserve the centric stops on the cusps which are normally in occlusion.

What is Turner's hypoplasia?

Turner's Tooth, also called Enamel Hypoplasia by professionals in the field, is a condition that reduces a tooth's enamel thickness, increases tooth sensitivity, leaves the affected tooth more susceptible to decay, and results in an unsightly appearance.

What does Anodontia mean?

Anodontia is a genetic disorder defined as the absence of all teeth. It usually occurs as part of a syndrome that includes other abnormalities. Also rare but more common than anodontia are hypodontia and oligodontia. Hypodontia is genetic in origin and usually involves the absence of from 1 to 5 teeth.

What is Microdontia?

Microdontia refers to teeth that are smaller than normal, whereas macrodontia (megadontia) relates to teeth that are larger than normal.

What is dilaceration of root?

By definition, dilaceration is an abnormal angulation or bend in the root and less frequently, the crown of a tooth. Most cases are idiopathic and have no clinical feature [1]. In limited cases with recognized cause, injury was the first reason.

How do you diagnose dilaceration?

Dilaceration of a crown can be visually observed in the mouth (provided the tooth is not impacted); however, radiographic examination is required to diagnose dilaceration in the root.

What causes external root resorption?

External resorption is often caused by injuries to the mouth and teeth that cause swelling and loss of bone and tissue on and around a tooth. Such injuries may occur from prolonged use of orthodontic appliances such as braces, or from tooth grinding or tooth bleaching.

Who was Neanderthal man and what were some of his defining characteristics?

Neanderthals had a long, low skull (compared to the more globular skull of modern humans) with a characteristic prominent brow ridge above their eyes. Their face was also distinctive. The central part of the face protruded forward and was dominated by a very big, wide nose.

What was Heidelberg Man brain size?

This skull was the first fossil of a human ancestor to be discovered in Africa. It combines primitive features such as a wide face, thick arching brow ridges and a sloping forehead with a large brain capacity of 1280 cubic centimetres.

Did Neanderthals have wisdom teeth?

So let's start from the beginning: the neanderthal human being. This historic human would often use his or her wisdom teeth to chomp down on particularly tough and gritty foods that your average, modern day human would not choose to eat.

Which feature is characteristic of pulp stones?

Pulp stones are discrete calcifications found in the pulp chamber of the tooth which may undergo changes to become diffuse pulp calcifications such as dystrophic calcification. They are usually noticed by radiographic examination and appeared as round or ovoid radiopaque lesions.

What is Hypotaurodont?

Hypotaurodont shows mild enlargement of the pulp chamber at the expense of the roots. In mesotaurodont the pulp shows moderate enlargement with short roots which are still separate, while in hypertaurodont the pulp chamber reaches the apical 3rd and then may break into two or four channels.

What is Amelogenesis imperfecta?

Amelogenesis imperfecta (AI) refers to a group of rare, inherited disorders characterized by abnormal enamel formation. The term is typically restricted to those disorders of enamel development not associated with other abnormalities of the body.

When does Turner's hypoplasia occur?

Hypoplasia is the result of disruption in the process of enamel matrix formation, which in turn causes defect in quality and thickness of enamel. Four cases of Turner's hypoplastic teeth with a previous history of trauma/infection in their primary predecessors at the age of 2-3 years have been reported.
