Front 3

abnormal concentration composed of mineral salts, usually occuring within the hollow organs or their passages; also called stones, such as gallstones or kidney stones

Ectopic

Front 6

examples are pulp stones, denticles, and salivary calculi

free of microorganisms; a germ-free animal in research is reared under completely sterile conditions

Back 7

Germ-free

Front 8

intercellular or intermicrobial substance of a tissue, or the tissue from which a structure develops, gains support and is held together.

Back 8

Matrix

Front 9

addition of mineral elements, such as calcium and phosphorus, to the body or part therof with resulting hardening of the tissue.

Back 9

Mineralization

Front 10

Nucleus; focus; point of origin.

Back 10

Nidus

Front 11

Inhibitor of calcification that occurs in parotid saliva of humans in variable amounts; anticalculus component of "tarter-control" dentrifrices

Back 11

Pyrophosphate

Front 12

holding all of a substance (solute) that can be dissolved in the solution

Back 12

Saturated

Front 13

a solution containing more of an ingredient than can be held in solution permanently

Back 13

Supersaturated

Front 14

imperfect formation of enamel; hereditary condition in which the ameloblasts fail to lay down the enamel matrix properly or at all

Back 14

Amelogenesis Imperfecta

Front 15

green plant pigment essential to photosynthesis

Back 15

Chlorophyll

Front 16

producing color or pigment

Back 16

Chromogenic

Front 17

arranged in order of time

Back 17

Chronologic

Front 18

hereditary disorder of dentin formation in which the odontoblasts lay down an abnormal matrix; can occur in both primary and permanent dentitions

Back 18

Dentinogenesis Imperfecta

Front 19

produced within or caused by factors within

Back 19

Endogenous

Front 20

originating outside or caused by factors outside

Back 20

Exogenous

Front 21

derived from a situated on the outside; external

Back 21

Extrinsic

Front 22

incomplete development or underdevelopment of an organ or a tissue

Back 22

Hypoplasia

Front 23

situated entirely within

Back 23

Intrinsic

Front 24

the depression in the gingival tissue under a contact area between the lingual (palatal) papilla and the facial papilla

Back 24

Col

Front 25

V-shaped spillway space next to the contact area of adjacent teeth, narrowest at the contact and widening toward the facial, lingual (palatal), and occlusal contacts

Back 25

Embrasure

Front 26

a cleft in the gingival margin usually at a mesial or distal line angle of a tooth where dental floss was repeatedly applied incorrectly. The lining of the cleft can be completely lined with epithelium

Back 26

Floss cleft

Front 27

unintentional incision at the gingival margin due to incorrect positioning and placement of dental floss.

Back 27

Floss Cut

Front 28

the triangular region bounded by the proximal surfaces of contacting teeth and the alveolar bone between the teeth, which forms the base of the triangle; the space is normally filled with the interdental papilla; also called the interdental area

Back 28

Interproximal Space

Front 29

outer, protective surface of stratified squamous epithelium; covers the masticatory mucosa; interdental col area is not normally keratinized

Back 29

Keratinized Epithelium

Front 30

another name for an interdental brush
