Apposition

addition of parts, fourth stage of development, mineral salts, and organic matter are set down and in place for tissues and tooth formation.

Attrition

abrasion or chafing, last stage of development, happens as teeth interact with each other via mastication and speech.

Axial

root to crown, long

bicuspid(s)

premolars, mandibular teeth

Bifurcation

Branching into two parts, mandibular molars have two roots

Buccal

check side/surface, posterior tooth surface toward the cheeks

Calcification

deposit of lime salts, fifth stage of development, the hardening and setting of tooth tissues.

Cementoblast(s)

Cementum-forming cells, encourages cell growth to form the root-covering cementum tissue.

Cementoclast(s)

cells that destroy tooth cementum.

Cementum

tissue covering of tooth root

Cervical line

the place where the enamel of the crown meets the cementum of the root.

Crown

the top part of the tooth containing the pulp chamber, dentin, and enamel covering.

Cusp

a point of the crown of a tooth, elevation, or mound on the biting surface of the crown

Cuspid(s)

canines, single-rooted anterior teeth at the corner of the mouth, longest tooth, splits anterior from posterior.

Deciduous

falling off, first set of teeth

Dens in dente

tooth in tooth, a tooth enfolds on itself to form a small cavity that holds a hard structure or mass

Dental lamina

membrane band containing organs of future teeth, develops in the epithelium

Dentin

the main tissue of tooth surrounding the pulp

Dentinogenesis imperfecta

inadequate dentin formation, a genetic disorder characterized by weakened or gray-colored teeth or shell teeth resulting from poor formation

Dentition

tooth arrangement

Differentiation

acquiring different functions from the original

Distal

to the distant, away, side surface of a tooth farthest from the midline of the face

Eminence

a high place, projection, or prominence.

Enamel

a hard tooth covering

Epithelium

mucous tissue covering and connective tissue layer

Eruption

breaking out, six stage of development. Cutting of the teeth, It occurs when the tooth moves toward the oral cavity and enters through the tissues.

Exfoliate

scale off

Facial

surface of all teeth toward the cheek and/or the lips

Fibroblast

fiber-forming germ cells, encourages cell growth to form the periodontal ligaments.

Fissure

a groove or natural depression, slit, or break;

Fluorosis

reaction to overfluoridation, mottled enamel

Foramen

an opening or hole in the bone for nerve and vessel passage

Fossa

a shallow, rounded, irregular depression or concavity on the lingual surface of anterior teeth and on the occlusal surfaces of posterior teeth.

Furcation

Fork or branch off, the place where tooth roots branch apart

Furrow

a shallow concave groove located on either the crown or the root, developmental depression.

Fusion

joining together, union of tooth buds resulting in large crown or root.

Germination

development of germ cells, single tooth germ separating to form two crowns on a single root

Gingiva

mouth tissue, mucous tissue surrounding the teeth, gives protection.

Groove

a rut, furrow, or channel. 2 types

teeth of various shapes

Histodifferentiation

branch into different tissues

overgrowth of cementum tissue, an anomaly resulting in a thickening of cementum, result of stress.

Hypocalcification

underbonding or incomplete calcification, lack of hardening of tooth tissue resulting in weak, susceptible teeth.

Hypoplasia

underdevelopment of tissue.

In utero

in the uterus

Incisal

to cut, cutting edge of anterior teeth (centrals, laterals, and cuspids/canines)

Incisors
