30 Cards in this Set

  • Front
  • Back
without definite shape or visible differentiation in structure
Amorphous
crystalline mineral component of bones and teeth that contains calcium and phosphate
Apatite
abnormal concentration composed of mineral salts, usually occuring within the hollow organs or their passages; also called stones, such as gallstones or kidney stones
Calculus
Demineralized dental biofilm covered on the external surface with vital, tightly adherent, nonmineralized biofilm
Denture Calculus
out of place; arising or produced at an abnormal site or in a tissue where it is not normally found
Ectopic
examples are pulp stones, denticles, and salivary calculi
Ectopic oral calification
free of microorganisms; a germ-free animal in research is reared under completely sterile conditions
Germ-free
intercellular or intermicrobial substance of a tissue, or the tissue from which a structure develops, gains support and is held together.
Matrix
addition of mineral elements, such as calcium and phosphorus, to the body or part therof with resulting hardening of the tissue.
Mineralization
Nucleus; focus; point of origin.
Nidus
Inhibitor of calcification that occurs in parotid saliva of humans in variable amounts; anticalculus component of "tarter-control" dentrifrices
Pyrophosphate
holding all of a substance (solute) that can be dissolved in the solution
Saturated
a solution containing more of an ingredient than can be held in solution permanently
Supersaturated
imperfect formation of enamel; hereditary condition in which the ameloblasts fail to lay down the enamel matrix properly or at all
Amelogenesis Imperfecta
green plant pigment essential to photosynthesis
Chlorophyll
producing color or pigment
Chromogenic
arranged in order of time
Chronologic
hereditary disorder of dentin formation in which the odontoblasts lay down an abnormal matrix; can occur in both primary and permanent dentitions
Dentinogenesis Imperfecta
produced within or caused by factors within
Endogenous
originating outside or caused by factors outside
Exogenous
derived from a situated on the outside; external
Extrinsic
incomplete development or underdevelopment of an organ or a tissue
Hypoplasia
situated entirely within
Intrinsic
the depression in the gingival tissue under a contact area between the lingual (palatal) papilla and the facial papilla
Col
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
Embrasure
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
Floss cleft
unintentional incision at the gingival margin due to incorrect positioning and placement of dental floss.
Floss Cut
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
Interproximal Space
outer, protective surface of stratified squamous epithelium; covers the masticatory mucosa; interdental col area is not normally keratinized
Keratinized Epithelium
another name for an interdental brush
Proxabrush
