enamel (redirected from enameling)

enamel /enam·el/ (ĕ-nam´'l)

1. the glazed surface of baked porcelain, metal, or pottery.

2. any hard, smooth, glossy coating.

3. dental enamel; the hard, thin, translucent substance covering and protecting the dentin of a tooth crown and composed almost entirely of calcium salts.

mottled enamel  dental fluorosis: hypoplasia of the dental enamel caused by drinking water with a high fluorine content during the time of tooth formation; characterized by defective calcification that gives a white chalky appearance to the enamel, which gradually undergoes brown discoloration.

enamel

[inam′əl]

Etymology: OFr, esmail

the hard, white substance that forms the outermost covering of the clinical and anatomic crown of a tooth. It contains no nerves or blood vessels and is the hardest bony substance in the body. It is produced by epithelial cells called ameloblasts.

enamel

(inam´l),
n 1. the hard, glistening tissue covering the anatomic crown of the tooth. It is composed mainly of hexagonal rods of hydroxyapatite, sheathed in an organic matrix (approximately 0.15%) and oriented with their long axes approximately at right angles to the surface.
n 2. the outermost layer or covering of the coronal portion of the tooth that overlies and protects the dentin.

enamel bonding,

v See bonding, enamel.

enamel hypocalcification

n a hereditary condition in which the enamel of the tooth has formed without adequate amounts of mineralization, leaving the surface of the tooth brittle and often stained.

enamel

the white, compact and very hard substance covering and protecting the dentine of the crown of a tooth.

---

enamel bulge

the area of greatest diameter of a tooth, just external to the gum line, which acts to deflect food from the free gingival margin and the gingival crevice.

enamel epithelium

epithelium which creates a bell-shaped enamel organ, surrounding the dental papilla; the internal epithelium consists of columnar ameloblasts which secrete enamel.

enamel hypoplasia

incomplete or partial development; a common defect in dogs.

inherited enamel defect

an inherited absence of enamel from all teeth combined with excessive flexibility of joints in Holstein-Friesian cattle. The teeth are pink and obviously deficient in substance. A defect in collagen formation is probable.

enamel layer

the outermost layer of cells of the enamel organ.

mottled enamel

dental fluorosis; defective enamel, with a chalky white appearance or brownish stain, caused by excessive amounts of fluorine in drinking water and food preparations during the period of enamel calcification.

enamel organ

an epithelial cap over a dental papilla that develops into the enamel-producing organ. The shape of the enamel organ determines the shape of the tooth.

enamel points

sharp projections of enamel at the junction of the buccal and occlusal surfaces of a tooth. Seen most commonly in horses.

enamel rods

progressively mineralized glycoproteinaceous tubules, the basic structural units of enamel; enamel is acellular and consists of interrod material and rods,

enamel spot

remnant of the enamel cup in the center of an incisor tooth table in a horse.

enamel works

factories manufacturing enamels or using them extensively; sources of fluorine for pollution of pasture and water.
