What is enamel pearl in dentistry?

Enamel pearls are one of a number of different enamel structures that can be found on the roots of deciduous and permanent teeth. They have a distinct predilection for the furcation areas of molar, particularly the maxillary third and second molars.

What forms an enamel Pearl?

According to an article in the Journal of Dental Sciences, enamel pearls form when enamel cells — called ameloblasts — travel below the gumline to the root and start producing enamel. This prevents the normal root covering from developing, leaving a nodule of enamel at the root instead of at the crown where it belongs.

How common is enamel Pearl?

Enamel pearls are estimated to occur in 1.1-9.7% of permanent molars, although higher rates are found when pearl detection is performed histologically instead of clinically. The highest prevalence of enamel pearls is found in the maxillary third molar, with an incidence of approximately 75%.

What does enamel mean in dentistry?

Tooth enamel is the thin outer covering of a tooth. It covers the crown of the tooth, which is the part you can see outside of the gums. Although it is the outer layer, enamel is see-through. Dentin, the hard tissue beneath the enamel, is what gives teeth their color.

Which location is the most likely for an enamel Pearl?

In the maxillary molars, the most prevalent anatomical location of enamel pearls in the first and second molars was the furcation between the distobuccal and palatal roots. Enamel pearls are a common observation in molars in general, but are most commonly found in maxillary molars.

PEARLS growing in her TEETH - Is this possible? - Enamel pearls

What does an enamel pearl look like?

Clinical features: The enamel pearl typically appears as a round, single, solid formation on the tooth root surface. The enamel pearl may vary in size from microscopic to a few millimeters.

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 dental enamel made of?

Enamel is comprised of the mineral calcium phosphate, arranged in a crystal structure known as hydroxyapatite. Sea shells are made from calcium carbonate. (So are pearls, for that matter) Both teeth and sea shells are more complex than they might first appear.

What kind of material is enamel?

Enamel is a material produced by fusing powdered glass to a substrate. It is fired with additive pigments. Covering steel elements with enamel protects the base material from rust, gives the ware a pleasing aesthetic, and guarantees health and safety when enamelware is used in the kitchen.

Can enamel be repaired?

Because enamel has no living cells, the body cannot repair chipped or cracked enamel.

Where are Cementicles found?

A cementicle is a small, spherical or ovoid calcified mass embedded within or attached to the cementum layer on the root surface of a tooth, or lying free within the periodontal ligament. They tend to occur in elderly individuals.

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 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 is the function of enamel?

Dental enamel is the hardest substance in the human body and serves as the wear-resistant outer layer of the dental crown. It forms an insulating barrier that protects the tooth from physical, thermal, and chemical forces that would otherwise be injurious to the vital tissue in the underlying dental pulp.

When is enamel formed?

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 is required for dental enamel?

The primary mineral is hydroxyapatite, which is a crystalline calcium phosphate. Enamel is formed on the tooth while the tooth develops within the jaw bone before it erupts into the mouth. Once fully formed, enamel does not contain blood vessels or nerves, and is not made of cells.

What are the types of enamel?

How many types of enamel are there?

Enamels exist in three basic clarities: opaque (not transparent), opalescent (semi-transparent) and transparent.

What is the difference between porcelain and enamel?

Difference Between Porcelain and Enamel

The finish is as durable as the one on your car, although much thicker, and like a car finish, it can chip and crack. However, with proper care, an enamel finish can last for years. Porcelain is basically ceramic that has been fired at high heat to make it smooth and nonporous.

Is enamel a keratin?

The discovery that hair keratins are present in mature enamel and play a crucial role in forming a cohesive and biomechanically stable enamel may have a significant impact on the design of novel enamel repair strategies.

What color is tooth enamel?

Enamel is on the surface of every tooth and it has a natural hue of white. However, the underlying dentin layer has a slightly yellowish color. This yellowish hue shows through the enamel in almost everyone, but more so for those with naturally thinner or more translucent enamel.

What are the three types of enamel thickness?

Three types of enamel hypoplasia: 1) lines; 2) pits; 3) groove.

What is a pink tooth?

A pulpal hemorrhage is defined as the escape of blood from a ruptured vessel, and blood is trapped inside of the pulp chamber, giving off a pink hue. Thus, the pink tooth is usually associated with internal resorption in the coronal area of a tooth [1.

What is Shell teeth?

Shell teeth, a rare dysplastic condition of dentin, was first described by Rushton in 1954. It is characterized by normal enamel, extremely thin dentin, correspondingly large pulp chambers, and shortened roots.

What happens if you swallow mercury filling?

Unlike other types of mercury, metallic mercury is essentially non-toxic if swallowed; it passes through a healthy gastrointestinal tract without being absorbed into the body or causing harm.
