Toothbrush: The toothbrush is an oral hygiene instrument used to clean the teeth and gums that consists of a head of tightly clustered bristles mounted on a handle, which facilitates the cleansing of hard-to-reach areas of the mouth.Abrasive saw: An abrasive saw, also known as a cut-off saw or metal chop saw, is a power tool which is typically used to cut hard materials, such as metals. The cutting action is performed by an abrasive disc, similar to a thin grinding wheel.Dentifrice: Dentifrices are agents used along with a toothbrush to clean and polish natural teeth. They are supplied in paste, powder, gel or liquid form.ToothpasteFranz Hein: Franz Hein (1892–1976) was a German scientist and artist.Pineapple black rot: Pineapple black rot, also known as butt rot, base rot, or white blister, is a disease caused by Ceratocystis paradoxa (Dade) Moreau (Anamorph: Thielaviopsis paradoxa (De Seyenes) Höhnel) is the most common and well-known post-harvest disease of the pineapple fruit which is responsible for serious losses in the fresh pineapple fruit world industry.Dental plaque: Dental plaque is a biofilm or mass of bacteria that grows on surfaces within the mouth. It appears as a white or pale yellow "slime layer", that is commonly found between the teeth and along the cervical margins.Heteropterys: Heteropterys is a genus in the Malpighiaceae, a family of about 75 genera of flowering plants in the order Malpighiales. Heteropterys comprises over 140 species of woody vines, shrubs, and small trees found in the New World tropics and subtropics from northern Mexico and the West Indies to northern Argentina and southeastern Brazil.Three-body forceHelsinki Motor ShowHorse teethSiloxane: A siloxane is a functional group in organosilicon chemistry with the Si–O–Si linkage. The parent siloxanes include the oligomeric and polymeric hydrides with the formulae H(OSiH2)nOH and (OSiH2)n.Smear layer: The smear layer is a layer of microcrystalline and organic particle debris that is found spread on root canal walls after root canal instrumentation. It was first described in 1975 and much research has been performed since then to evaluate its importance in assisting or preventing the penetration of bacteria into the dentinal tubules.HeptaneDental cariesApical 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.NanotoughBrittlenessPhosphoramidate: A phosphoramidate is a phosphate that has an NR2 instead of an OH group. The structure of phosphoramidic acid (phosphoramidate), (HO)2PONH2, is present in PubChem.ListerineHome appliance: Home appliances are electrical/mechanical machines which accomplish some household functions, such as cooking or cleaning. Home appliances can be classified into:WKT (sealant): WKT is sealing compound which was developed by Paul Pietzschke, Chemisch-Technische Fabrik, Hamburg, Germany in 1962 specifically to meet the stringent requirements in the yacht and ship building industry. WKT belongs to the silicone group of sealants.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.Oil immersionTufting (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.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.Sports drink: Sports drinks are beverages whose stated purpose is to help athletes replace water, electrolytes, and energy after training or competition, though their efficacy for that purpose has been questioned, particularly after exercise which is only moderate.ChlorhexidineSurface 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.
