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.

What causes Turner's hypoplasia?

When Turner's hypoplasia is found on a canine or a premolar, it is most likely caused by an infection that was present when the primary tooth was still in the mouth. Most possibly, the primary tooth was heavily decayed and an area of inflamed tissues around the root apex affected the development of the permanent tooth.

What stage of development does enamel hypoplasia occur?

Enamel hypoplasia occurs when the special cells that produce dental enamel are disturbed during a particular stage of enamel formation (the matrix formation stage). A wide variety of factors can potentially cause such a disturbance, including both genetic and environmental factors.

When does linear enamel hypoplasia occur?

[18] Environmental enamel hypoplasia/hypomineralization due to systemic factors are commonly manifested in the first permanent molars and incisors. Clinical studies indicate that enamel hypoplasia involve those teeth that form within the 1^st year of birth.

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.

ENAMEL HYPOPLASIA(TURNERS TOOTH

What causes Turner tooth?

It may be caused by trauma to an associated primary tooth or due to a primary tooth with a periapical inflammatory lesion; the result is a disturbance in the enamel formation (amelogenesis) of the developing unerupted permanent tooth. The labial surface is the most likely surface affected.

What is the cause of local hypoplasia of permanent tooth?

Hypoplasia Caused by Local Infection and Trauma

Individual permanent teeth often have hypoplastic or hypocalcified areas on the crown that result from infection or trauma (Figs.

What is Turner's tooth?

An enamel defect in the permanent teeth caused by periapical inflammatory disease in the overlying primary tooth is referred to as Turner's tooth (also known as Turner's hypoplasia).

What causes enamel hypoplasia in infants?

Environmental Causes of Enamel Hypoplasia

Tooth injury. Infections. Calcium deficiency. Vitamin A, C, or D deficiency.

What is the difference between amelogenesis imperfecta and enamel hypoplasia?

Enamel Hypoplasia can be related either to hereditary causes, affecting all the teeth on both dentitions or acquired ones, involving one or more teeth (Figure 3). When Hypoplasia is related to a hereditary cause it can be also called Amelogenesis Imperfecta.

How do you detect enamel hypoplasia?

How is enamel hypoplasia detected?

You could be noticing enamel hypoplasia. This condition is a defect that causes a lesser quantity of enamel than normal. It can appear as a white spot, yellow to brown staining, pits, grooves or even thin, chipped or missing parts of enamel. In severe cases, the enamel doesn't develop at all.

When does enamel form permanent teeth?

Enamel formation on a child's permanent teeth begins during infancy and continues until somewhere around age 7 or 8 (with the exception of the enamel on the wisdom teeth, which forms later). The enamel is produced by special cells called ameloblasts.

What are the white spots on my child teeth?

Tooth Decay In children, tooth decay often presents first as white spots, often situated near the gum line. This is not the same as the yellowing associated with plaque or tartar formation. Instead, decay will appear as a milky or chalky white color on teeth, which will eventually turn to brown as the decay advances.

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.

How common is hyperplasia teeth?

In fact, in one 2009 study, in which nearly 500 children were surveyed, 4 percent of children had enamel hypoplasia. Among those children, 37 percent had cavities at age five, compared to 17 percent of children without hypoplasia.

When do teeth develop in utero?

The first stage begins in the fetus at about 6 weeks of age. This is when the basic substance of the tooth forms. Next, the hard tissue that surrounds the teeth is formed, around 3 to 4 months of gestation. After the child is born, the next stage occurs when the tooth actually protrudes through the gum.

What causes decalcification on baby teeth?

There are several causes of decalcification: improper brushing habits that result in plaque building up on teeth and consuming drink and foods that have sugars and acids, such as sodas, juice, tea and even milk. Dry mouth can cause areas of decalcification. Without saliva, a fry mouth remains acidic.

Why are my toddler's teeth transparent?

Why do my child's teeth look translucent? Tooth enamel is naturally translucent, or mostly clear – the “color” of teeth that we are accustomed to seeing is the material behind it, known as dentin. Because children's teeth have less dentin, their teeth normally look brighter and more translucent.

What causes hypoplastic molars?

Hypoplastic teeth, also known as enamel hypoplasia, is when your enamel has not formed properly or has formed incorrectly. There are many reasons why this might happen, including diseases, prenatal issues, and environmental conditions.

Does Turner syndrome affect teeth?

Commonly seen dental health features in girls/women with Turner Syndrome: Variation in tooth eruption. Changes in crown and root development. Increased risk for root absorption or tooth loss during orthodontic treatment.

When should I worry that my baby has no teeth?

A slight delay is fine, but it may be time to see your dentist if your child has no teeth at 18 months. Delayed tooth eruption usually isn't a major cause for concern, but it never hurts to check.

What is the difference between hypoplasia and Hypomineralization?

If a disturbance occurs during the secretion phase, the enamel defect is called hypoplasia. If it occurs during the mineralisation or maturation phase, it is called hypomineralisation. Often the cause is difficult to determine.

How can you distinguish between enamel hypoplasia and fluorosis?

In other words, there is an insufficient or incomplete formation of the organic matrix, called hypoplasia. A qualitative anomaly occurs when the enamel has normal thickness, but presents changes in its translucency (hypomineralisation), and is called dental fluorosis.

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.
