Crown (dentistry)Talon cuspCrown etherOpine: Opine biosynthesis is catalyzed by specific enzymes encoded by genes contained in a small segment of DNA (known as the T-DNA, for 'transfer DNA'), which is part of the Ti plasmid, inserted by the bacterium into the plant genome. The opines are used by the bacterium as an important source of nitrogen and energy.Porcelain: Porcelain is a ceramic material made by heating materials, generally including kaolin, in a kiln to temperatures between . The toughness, strength and translucence of porcelain, relative to other types of pottery, arises mainly from vitrification and the formation of the mineral mullite within the body at these high temperatures.Veneer (dentistry): In dentistry, a veneer is a layer of material placed over a tooth, either to improve the aesthetics of a tooth or to protect the tooth's surface from damage. There are two main types of material used to fabricate a veneer: composite and dental porcelain.Thread-locking fluid: Thread-locking fluid or threadlocker is a thin, single-component adhesive, applied to the threads of fasteners such as screws and bolts to prevent loosening, leakage, and corrosion.A Plague of Lighthouse Keepers: "A Plague of Lighthouse Keepers" is a track from the English band Van der Graaf Generator's fourth album Pawn Hearts (1971). It is a concept piece over 23 minutes long, which comprises the whole B-side of the album.TebisZirconium phosphate: Zirconium phosphates (zirconium hydrogen phosphate) are acidic, inorganic cation exchange materials that have a layered structure with formula Zr(HPO4)2∙nH2O.Clearfield, A.OverjetSpin casting: Spin casting, also known as centrifugal rubber mold casting (CRMC), is a method of utilizing centrifugal force to produce castings from a rubber mold. Typically, a disc-shaped mold is spun along its central axis at a set speed.MalocclusionApical delta: Apical delta refers to the branching pattern of small accessory canals and minor foramina seen at the tip or apex of some tooth roots.CeramicAbutment (dentistry): In dentistry, an abutment is a connecting element. This is used in the context of a fixed bridge (the "abutment teeth" referring to the teeth supporting the bridge), partial removable dentures (the "abutment teeth" referring to the teeth supporting the partial) and in implants (used to attach a crown, bridge, or removable denture to the dental implant fixture).Vertical root fractureThree-body forceWhite Portland cement: White Taavo Portland cement or white ordinary Portland cement (WOPC) is similar to ordinary, gray Portland cement in all aspects except for its high degree of whiteness. Obtaining this color requires substantial modification to the method of manufacture, and because of this, it is somewhat more expensive than the gray product.Glazing agent: A glazing agent is a natural or synthetic substance that provides a waxy, homogeneous, coating to prevent water loss from a surface and provide other protection.Neonatal line: The neonatal line is a particular band of incremental growth lines seen in histologic sections of a deciduous tooth. It belongs to a series of a growth lines in tooth enamel known as the Striae of Retzius.BrittlenessHuman tooth: The human teeth function in mechanically breaking down items of food by cutting and crushing them in preparation for swallowing and digestion. There are four different types of teeth, namely incisors, canines, molars and premolars.Tufting (composites): In the field of composite materials, tufting is an experimental technology to locally reinforce continuous fibre-reinforced plastics along the z-direction, with the objective of enhancing the shear and delamination resistance of the structure.Nordic Institute of Dental Materials: NorwayLarge ornamented Ediacaran microfossil: Large ornamented Ediacaran microfossils (LOEMs) are microscopic acritarchs, usually over 100 μm in diameter, which are common in sediments of the Ediacaran period, . They largely disappear from the Ediacaran fossil record before , roughly coeval with the origin of the Ediacara biota.Enamel spindles: Enamel spindles are "short, linear defects, found at the dentinoenamel junction (DEJ) and extend into the enamel, often being more prevalent at the cusp tips."Histology Course Notes: "Mature Enamel", New Jersey Dental School, 2003-2004, page 2.Silicide: A silicide is a compound that has silicon with (usually) more electropositive elements.PolycarbonatePotassium fluoride on alumina: Potassium fluoride on alumina (KF/Al2O3) is a chemical agent consisting of potassium fluoride and aluminium oxide. It is a base which is used in organic synthesis.ProsthodonticsSurface modification: Surface modification is the act of modifying the surface of a material by bringing physical, chemical or biological characteristics different from the ones originally found on the surface of a material.Surgical stainless steel: Surgical stainless steel is an informal term which refers to certain grades of stainless steel that are used in biomedical applications. The most common "surgical steels" are austenitic 316 stainless and martensitic 440 and 420 stainless steels.Endodontic therapy: Endodontic therapy or root canal therapy is a sequence of treatment for the infected pulp of a tooth which results in the elimination of infection and the protection of the decontaminated tooth from future microbial invasion. Root canals and their associated pulp chamber are the physical hollows within a tooth that are naturally inhabited by nerve tissue, blood vessels and other cellular entities which together constitute the dental pulp.Motorola PageWriter 2000: The Motorola PageWriter 2000 was a two-way pager introduced in 1998.Motorola is offering the Cadillac of pagers with...Depletion gilding: Depletion gilding is a method for producing a layer of nearly pure gold on an object made of gold alloy by removing the other metals from its surface. It is sometimes referred to as a "surface enrichment" process.Abfraction: Abfraction is a theoretical concept explaining a loss of tooth structure not caused by tooth decay (non-carious cervical lesions). It is suggested that these lesions are caused by forces placed on the teeth during biting, eating, chewing and grinding; the enamel, especially at the cementoenamel junction (CEJ), undergoes large amounts of stress, causing micro fractures and tooth tissue loss.Pearlescent coatingStagemasterRhizobiaMannosylfructose-phosphate synthase: Mannosylfructose-phosphate synthase (, mannosylfructose-6-phosphate synthase, MFPS) is an enzyme with system name GDP-mannose:D-fructose-6-phosphate 2-alpha-D-mannosyltransferase. This enzyme catalyses the following chemical reactionBrightray: Brightray is a nickel-chromium alloy that is noted for its resistance to erosion by gas flow at high temperatures. It was used for hard-facing the exhaust valve heads and seats of petrol engines, particularly aircraft engines from the 1930s onwards.Iron metallic discoloration: Iron metallic discoloration occurred more frequently in the past when soluble iron compounds were used in the treatment of allergic contact and other dermatitis, and in eroded areas iron was sometimes deposited in the skin, like a tattoo .James, William; Berger, Timothy; Elston, Dirk (2005).TypodontEnamel hypoplasiaGlass ionomer cement: A glass ionomer cement is a dental restorative material used in dentistry for dental fillings and luting cements. These materials are based on the reaction of silicate glass powder and polyalkenoic acid, an ionomer.John o' Groats: John o' Groats (Gaelic: Taigh Iain Ghròt) is a village in the Canisby parish of Caithness, in the far north of Scotland. John o' Groats lies on Britain's northeastern tip, and is popular with tourists as one end of the longest distance between two inhabited British points, with Land's End in Cornwall lying 876 miles to the southwest.Dentin sialophosphoprotein (protein): Dentin sialophosphoprotein is the only protein produced uniquely by odontoblasts, the cells that produce tooth dentin. It is a non-collagenous SIBLING protein that is later cleaved into three functional proteins: dentin phosphoprotein (also known as phosphophoryn), taken from the C-terminal end, dentin sialoprotein from the N-terminal end, and dentin glycoprotein from the middle of the molecule.Peat swamp forest: Peat swamp forests are tropical moist forests where waterlogged soil prevents dead leaves and wood from fully decomposing. Over time, this creates a thick layer of acidic peat.Inlays and onlaysOvereruption: In dentistry, overeruption is the physiological movement of a tooth lacking an opposing partner in the dental occlusion. Because of the lack of opposing force and the natural eruptive potential of the tooth there is a tendency for the tooth to erupt out of the line of the occlusion.Running room (dentistry): In implant dentistry, running room refers to the apico-coronal distance between the platform of a dental implant and the gingival margin. It is a critical factor in restorative implant dentistry because it is effectively the "vertical distance [available subgingivaly] to make a transition from the smaller diameter prosthetic platform of an implant to the larger cross-sectional cervical shape of the tooth being restored.Horse teethBorosilicate glass: Borosilicate glass is a type of glass with silica and boron trioxide as the main glass-forming constituents. Borosilicate glasses are known for having very low coefficients of thermal expansion (~3 × 10−6 /°C at 20 °C), making them resistant to thermal shock, more so than any other common glass.Blue colour works: A blue colour works () is a paintworks where blue paint for use in glassmaking is produced. Usually the pigment, cobalt blue, needed for this purpose, was manufactured from cobalt-containing ore as in the case of the factories listed below.
