When does taurodontism occur?

Taurodontism is believed to arise from a field effect and all molars are generally involved, the first molar being least affected, and with increased severity in the second and third molars, respectively (Fig. 3).

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 taurodontism of teeth?

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. It appears most frequently as an isolated anomaly.

Which tooth is most commonly affected by taurodontism?

Although permanent molar teeth are most commonly affected, reports have indicated that taurodontism may not be limited to molars, as it also occurs in the premolar teeth. Taurodontism may complicate endodontic, orthodontic and/or prosthetic treatment planning.

Taurodontism and MCQs

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 is taurodontism anthropology?

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

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 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 is cause Hypercementosis?

Hypercementosis is excessive deposition of cementum on the tooth roots. In most cases, its cause is unknown. Occasionally, it appears on a supraerupted tooth after the loss of an opposing tooth. Another cause of hypercementosis is inflammation, usually resulting from rarefying or sclerosing osteitis.

What causes condensing osteitis?

Inflammation and infections are thought to be the primary causes of condensing osteitis, which may be associated with other dental conditions. Pulpitis is one possible condition linked to this dental disease, which destroys tissue inside your teeth.

What are ghost teeth?

Regional odontodysplasia (RO) is a rare condition that gives teeth a fuzzy appearance in x-rays. These shadowy images are why this disorder has been given the more memorable nickname, "ghost teeth." But regional odontodysplasia doesn't just impact how your teeth look.

What is the second tooth in hypodontia?

The second premolars – these are the teeth right in front of your molars. One may sometimes be removed during braces treatment, but if your child is missing this permanent tooth, chances are it's due to hypodontia.

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 causes cusp of Carabelli?

Put simply, the cusp of Carabelli is just an extra bump on one or two of your teeth. According to the Journal of Clinical and Diagnostic Research, these possibly form from overactivity of the dental lamina, one part of tooth development.

Which teeth are most affected by root Dilaceration?

Results: Root dilaceration was detected in 0.3% of teeth and 7.2% of patients. It was distributed equally between the maxilla and mandible. Mandibular second molar was the most frequent dilacerated tooth (1.6%) followed by maxillary first molar (1.3%) and mandibular first molar (0.6%).

What is the difference between dentin dysplasia and Dentinogenesis imperfecta?

A. Dentinogenesis imperfecta: The teeth are translucent and often roughened with severe amber discolouration. B. Dentine dysplasia: The primary teeth are translucent and amber in colour whereas the erupting secondary central incisors are of normal appearance.

How common is Dentinogenesis imperfecta?

It is inherited in an autosomal dominant pattern, as a result of mutations on chromosome 4q21, in the dentine sialophosphoprotein gene (DSPP). It is one of the most frequently occurring autosomal dominant features in humans. Dentinogenesis imperfecta affects an estimated 1 in 6,000-8,000 people.

What is meant by opalescent teeth?

Human tooth enamel is opalescent, which renders teeth bluish in reflected and orange in transmitted color. The aim was to review opalescent property of teeth and application and mimetic reproduction in esthetic restorations.

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 rounded teeth?

Early Symptoms of Tooth Erosion

The ridges of the enamel wear away, leaving a flatter or more rounded surface; similarly, the sharper edges of teeth like canines and incisors will also appear rounded because the enamel wears away across the parts of the tooth most commonly in contact with food.

Why are my teeth curved at the bottom?

Crooked bottom teeth can be caused by a narrow lower jaw or natural shifts in your teeth over time, among other reasons. Depending on the severity of your crooked teeth, treatment may include braces, invisible teeth aligners, a fixed retainer, or oral surgery. Transform your smile with Clear Aligners.

What does Taurodont mean?

Medical Definition of taurodont

: having the pulp cavities of the teeth very large and the roots reduced a taurodont tooth.

What is Microdontia?

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

Do humans have Taurodont teeth?

In modern societies, taurodontism has been reported to account for less than about 5% of the human population, even though a wide discrepancy in the prevalence of the trait has been observed due to ethnic variations and different criteria used to interpret this trait (Jafarzadeh et al. 2008).
