  Tooth Enamel
Enamel is the outer layer of the exposed tooth.
Enamel is translucent (semi-transparent) and ranges in color from yellow to gray-white, with the range of colors due to varying thickness of enamel.
Enamel is composed of thin rods (enamel prisms) held together by a cementing substance, and surrounded by an enamel sheath.

 Tooth Enamel Restoration Information
An individual tooth consists of an exposed crown and a root, buried in the gum and jaw.
Tooth enamel, which is the hard, shiny outermost layer, largely consists of a form of the mineral calcium phosphate.
Beneath the enamel (and sometimes exposed to the surface if the enamel is missing or worn away) is an intermediate layer of material called dentine, which is also similar to bone but is not nearly as hard as enamel.

 23. Tooth and Gingiva
The gingiva is a mucosa (composed of an epithelium with underlying connective tissue) and its attachment to the tooth is of particular importance in dentistry.
In the early life of an erupted tooth, the gingival epithelium attaches to the enamel at the base of the crown region through the epithelial attachment.
The tissues have shrunk considerably during fixation so scan around to find individual areas where the dentin and enamel remain attached (illustration), where the odontoblasts are in contact with the dentin they have produced (illustration), and where the ameloblasts are attached to their enamel surface (illustration).

 Tooth Decay - Definition, Description, Causes, Symptoms, Diagnosis, Treatment, Prognosis, Prevention
Tooth decay is the second most common health problem after the common cold (see common cold entry).
A tooth may be sensitive to the touch, to hot or cold temperatures, or to very sweet foods.
The sooner tooth decay is treated, the less of a problem it is. Without treatment, decay attacks more and more of a tooth, which may make it necessary for a root canal.

 Tooth Anatomy
When you are looking at a tooth in the mouth, you are seeing millions of these little enamel rods packed side by side, but you are seeing them end-on, as in the illustration on the right which is a reasonable representation of their cross section.
The tooth is formed from the outside toward the inside, with the dental pulp slowly replacing itself with tooth structure.
Cementum is to the root of a tooth as enamel is to the crown.

 Fluoride intake and sky-rocketing fluorosis rates
In the process of enamel mineralization during amelogenesis (a unique model for the cell-mediated formation of well-crystallized carbonatoapatite), free fluoride ions in the fluid phase are supposed to accelerate the hydrolysis of acidic precursor(s) and increase the driving force for the growth of apatitic mineral.
The purpose of the present study was to assess whether the degree of severity of enamel changes in a population exhibiting rather severe dental fluorosis may be related to posteruptive tooth age and to describe the clinical manifestations of the enamel destructions.
The prevalence of enamel hypoplasia in 251 9-10-year-old children born and raised in a fluoridated city (Birmingham) was compared with that in 319 similar children born and raised in a non-fluoridated city (Leeds).

 Neuroscience For Kids - tooth
The outside of the tooth, the enamel, is the hardest tissue in the human body.
Rather, touching the tooth activates nerve fibers in the periodontal ligament (the ligament that surrounds the tooth) that are very sensitive to slight displacement of the tooth.
However, if the tooth is damaged by decay or trauma, the nerve fibers inside the tooth may respond to external stimuli and when they are, you are sure to feel pain.

 What is tooth decay?
The formation of tooth decay ("cavities") can be a significant problem for some individuals, either as children or adults.
Tooth decay can, however, be prevented to a very great degree if the person understands and practices just a very few basic concepts.
In short, tooth decay is a location on a tooth where so much of the tooth's mineral content as been dissolved away that a defect (a hole or a "cavity") has formed.

 tooth enamel? - Children with Diabetes Forums
AIM: This was to investigate the prevalence of enamel developmental defects in a group of children with a history of coeliac disease.
Enamel defects were diagnosed and classified according to criteria described by Aine [1986], while dental caries was recorded as DMFT(S) and dmft(s) indices [Koch, 1970].
In a study from Finland in 1986 it was shown that celiac disease was often associated with tooth enamel defects of permanent teeth.

 Tooth decay - Genesis Health System
Tooth decay is a common health problem, second in prevalence only to the common cold.
When the decay reaches the center of the tooth (the pulp), the resulting inflammation (pulpitis) produces a toothache.
If the pulp of the tooth is infected, the infection may be treated with antibiotics prior to root canal treatment or extraction.

 Dinosaur Tooth Enamel: A Key To Investigating Ancient Climate On Land
The key to infer past temperatures using tooth enamel is in measuring small differences in the chemical composition of oxygen in dinosaur tooth enamel, in particular, differences in the ratio of heavy (oxygen-18) to light (oxygen-16) oxygen.
This 'oxygen isotope ratio' of enamel is directly related to the isotopic ratio of rain and snow falling on a local area.
Fortunately the oxygen isotope ratio of tooth enamel does not change over the millions of years that a dinosaur fossil is buried, so it is possible to use this ratio to infer surface temperature when the dinosaur was actually alive.

 Introduction: Tooth Disorders: Merck Manual Home Edition
Tooth decay, which often leads to toothache and tooth loss, is largely preventable with good oral hygiene to remove plaque and prevent tartar buildup.
Abnormal tooth color is not the same as the darkening or yellowing of teeth that occurs as a person grows older or exposes his teeth to staining substances, such as coffee, tea, and cigarette smoke.
Abnormal tooth enamel (enamel is the hard outer surface of teeth) may be due to a diet containing insufficient vitamin D. Abnormal enamel may also be the result of a childhood infection (such as measles or chickenpox) occurring when the permanent teeth were forming.

 Tooth decay (Dental caries or cavities)
Dental caries is caused by the loss of minerals from the tooth enamel due to the action of acids produced by dental plaque.
Tooth decay can then penetrate through the protective enamel down to the softer, vulnerable dentine and continue to the soft tooth pulp and the sensitive nerves within it.
Tooth decay begins with a small patch of demineralised enamel at the tooth surface, often hidden from sight in the fissures or in between the teeth.

 Broken Tooth | AHealthyMe.com
Tooth enamel is made of the hardest substances in the human body, but teeth still have their breaking point.
Each tooth has three layers: enamel, the hard outer coating; dentin, the main part of the tooth; and pulp, the fleshy nerve center.
The tooth still shouldn't hurt too much, but it may be very sensitive to cold.

 ScienceDaily: New Tooth Enamel Dating Technique Could Help Identify Disaster Victims
Scientists can relate theextensive atmospheric record for carbon-14 to when the tooth was formedand calculate the age of the tooth, and its owner, to an accuracy ofwithin about 1.6 years.
The enamel separations were done at the KarolinskaInstitute, and sample preparation and accelerator mass spectrometryanalysis was done at Lawrence Livermore.
The enamel datingtechnique doesn't work for people born before 1943, because all oftheir teeth would have been formed before testing began in 1955.
