Anodontia

Absence of teeth

Differentiation

Acquiring different functions from the original

Apposition

Addition of parts

Osteoblasts

Bone forming germ cells

Root

Bottom part of a tooth

Eruption

Breaking out

Odontoclasts

Bring about absorption of primary tooth roots

Fifth Stage of Development

Calcification

Osteoclasts

Cause absorption of bone tissue

Cementoblasts

Cementum forming cells

Attrition

Chafing or abrasion

Tubules

Channels extending from dentinoenamel wall to pulp chamber

Pulp cyst

Closed, fluid-filled sac within the pulp tissue

Mesenchyme

Connective tissue cells

Tooth bud consists of...

Dental organ, dental papilla, and dental sac

Odontoblasts

Dentin forming cells

Primary dentin

Dentin in newly formed tooth

Calcification

Deposit of lime salts

Cementoclasts

Destroy tooth cementum

Midline

Determines right and left sides

Third Stage of Development

Differentiation

Granuloma

Growth or tumor found in root area

Enamel

Hard tooth covering

Fibers

Help the dentin to nourish and register sensation

Marginal

Helps to form the sides of the gingival crevice

Differentiation occurs in two ways...

Histodifferentiation, morphodifferentiation

First Stage of Development

Initiation

Tuft

Irregular grouping of undercalcified enamel

Hypocalcification

Lack of hardening of tooth tissue

Macrodontia

Large teeth

Line/stripes of Retzius

Lines in enamel

Axial surfaces

Long length surface of the tooth

Dentin

Main tissue of tooth surrounding the pulp

Which root is trifurcated?

Maxillary molar teeth

Point angle

Meeting of three surfaces of a tooth

Line angle

Meeting of two surfaces

Periodontal

Membrane and fibers that anchor the tooth in the alveolar socket

Dental lamina

Membrane band containing organs of future teeth

Mesoderm

Middle layer

Supernumerary

More than the normal amount of teeth

Epithelium

Mucous tissue covering and connective tissue layer

Gingiva

Mucous tissue surrounding teeth that protects teeth and underlying tissues

Papillary

Occupies the interproximal spaces

Irregular secondary dentin

Occurs as protection from irritation, decay, trauma, attrition

Regular secondary dentin

Occurs during regular development and maturing of tooth

Diastema

Open contact area

Antagonist

Opposing tooth

Hypercementosis

Overgrowth of cementum tissue

Succedaneous

Permanent teeth

Cervical line

Place where enamel of the crown meets the cementum of the root

Dental sac

Pocket covering

Rods

Prism like structures that extend from the dentinoenamel junction to the outer surface

Amelogensis

Process of forming tooth enamel

Second Stage of Development

Proliferation

The function fo the cementum in the periodontium is to...

Provide surface anchorage for the tooth in the alveolar socket

Fluorosis

Reaction to overfluoridation

Apex

Tip end of a tooth

Cementum

Tissue covering the tooth root

Dental papilla

Tissue development giving rise to dentin, pulp

Cuticle

Tissue layer covering the tooth surfaces

Dentition

Tooth arrangement

Dens in dente

Tooth in tooth

Pulpitis

Toothache

Crown

Top part of the tooth

Hypoplasia

Underdevelopment of tissue

Fusion

Union of tooth buds resulting in large crown or root

Embrasure

V shaped area located between the contact point of two teeth and the gingival crest

Dentinogenesis imperfecta

Weakened or gray-colored teeth or shell teeth resulting from poor formation

Two classifications of crowns

Anatomical and clinical

Periodontium

Anchorage, support, and protection of the teeth

Fourth Stage of Development

Apposition

CemKeratinized

Area where gingiva and mucous membrane unite

Final Stage of Development

Attrition

Lamellae

Cracks in enamel tissue toward or into dentin

Ameoloblasts

Enamel forming cells

Dental organ

Enamel organ

Gnarled enamel

Enamel rod twisting and curving

Spindles

End areas of union of odontoblasts and enamel rod endings

Sixth Stage of Development

Eruption

Deciduous

Falling off

Fibroblasts

Fiber forming germ cells

Odontogenesis

Formation and the origin of the tooth

Imperfecta

Formation of defective enamel

When does proliferation begin?

Fourth or fifth month in utero

Resorption

Removal of hard tooth surface

Proliferation

Reproduction of new parts

Hutchinsonian incisors

Saw like incisal edges of maxillary incisors

Exfoliate

Scale off

Proximal surface

Side wall of tooth that meets/touches the side wall of another tooth

Germination

Single tooth germ separating to form two crowns on a single root

Canaliculi

Small channels or canals

Pulp stone

Small growth in a tooth

Lacuna

Small open space
