• Cracks
  • Dental veneers may be used by many patients to address minor breaks, chips, or cracks. (midvalleychamber.com)
  • Extrinsic stains can become internalised through enamel defects or cracks or as a result of dentine becoming exposed but most extrinsic stains appear to be deposited on or in the dental pellicle. (wikipedia.org)
  • adhesive
  • Similarly, adhesives are also used in the bonding of dental materials (e.g., orthodontic appliances, generally utilizing an orthodontic adhesive) to a dental structure. (google.com)
  • Typically, such pretreatment steps include etching using, for example, inorganic or organic acids, followed by priming to improve the bonding between the tooth structure and the overlying adhesive. (google.com)
  • Pressure-sensitive adhesive (PSA, self-adhesive, self-stick adhesive) is adhesive which forms a bond when pressure is applied to marry the adhesive with the adherend. (wikipedia.org)
  • As the name "pressure-sensitive" indicates, the degree of bond is influenced by the amount of pressure which is used to apply the adhesive to the surface. (wikipedia.org)
  • In contrast, pressure-sensitive adhesives (PSAs) form a bond simply by the application of light pressure to marry the adhesive with the adherend. (wikipedia.org)
  • The bond forms because the adhesive is soft enough to flow, or wet, the adherend. (wikipedia.org)
  • The bond has strength because the adhesive is hard enough to resist flow when stress is applied to the bond. (wikipedia.org)
  • Once the adhesive and the adherend are in proximity, there are also molecular interactions such as van der Waals forces involved in the bond, which contribute significantly to the ultimate bond strength. (wikipedia.org)
  • citation needed] The adhesive bonding of a tape or label can be affected by its shape. (wikipedia.org)
  • caries
  • More particularly, this invention relates to a method of attaching a dental device (e.g. crown, bridge, cap, filling, etc.) to a prepared tooth structure and a system for implementing same so as to protect both the prepared tooth structure from recurrent caries and the integrity of the dental device once it is attached to the tooth structure. (google.com)
  • Causes of intrinsic staining include: Dental caries (tooth decay) Dental trauma which may cause staining either as a result of pulp necrosis or internal resorption. (wikipedia.org)
  • amalgam
  • Dental amalgam is a liquid mercury and metal alloy mixture used to fill cavities caused by tooth decay. (wikipedia.org)
  • There are, according to Geir Bjørklund, indications that dental amalgam was used in the first part of the Tang Dynasty in China (AD 618-907), and in Germany by Strockerus in about 1528. (wikipedia.org)
  • Evidence of a dental amalgam first appears in the Tang Dynasty medical text Hsin Hsiu Pen Tsao(《新修本草》) written by Su Kung(苏恭)in 659, manufactured from tin and silver. (wikipedia.org)
  • It was during the Ming Dynasty that the composition of an early dental amalgam was first published, and a text written by Liu Wen Taiin 1505 states that it consists of "100 shares of mercury, 45 shares of silver and 900 shares of tin. (wikipedia.org)
  • However, at that point the use of dental amalgam was declared to be malpractice, and the American Society of Dental Surgeons (ASDS), the only US dental association at the time, forced all of its members to sign a pledge to abstain from using the mercury fillings. (wikipedia.org)
  • This was the beginning of what is known as the first dental amalgam war. (wikipedia.org)
  • The American Dental Association (ADA) was founded in its place in 1859, which has since then strongly defended dental amalgam from allegations of being too risky from the health standpoint. (wikipedia.org)
  • Dental amalgam is produced by mixing liquid mercury with an alloy made of silver, tin, and copper solid particles. (wikipedia.org)
  • The composition of the alloy particles are controlled by the ISO Standard (ISO 1559) for dental amalgam alloy in order to control properties of set amalgam such as corrosion and setting expansion. (wikipedia.org)
  • It is important to differentiate between dental amalgam and the amalgam alloy that is commercially produced and marketed as small filings, spheroid particles, or a combination of these, suitable for mixing with liquid mercury to produce the dental amalgam. (wikipedia.org)
  • material
  • volts versus a silver/silver nitrate reference electrode, and wherein the polymerizable composition is a dental material suitable for use in the oral environment. (google.co.uk)
  • Bonding is a process in which an enamel-like material is applied to a tooth`s surface, sculpted to an ideal shape, hardened, and then polished for an ideal smile. (drstoner.com)
  • A ceramic is an inorganic compound, non-metallic, solid material comprising metal, non-metal or metalloid atoms primarily held in ionic and covalent bonds. (wikipedia.org)
  • periodontal disease
  • Although daily brushing provides the best preventative measure, feeding a dental diet or using dental chews for dogs is an effective approach pet owners can take to help prevent and control accumulation of plaque and tartar to avoid consequences of severe periodontal disease. (wikipedia.org)
  • Using a dental diet may be beneficial towards preventative care in regards to periodontal disease. (wikipedia.org)
  • composites
  • Whether for application of dental restoratives (e.g., cured or uncured composites such as glass ionomer cements, modified glass ionomer cements, etc. (google.com)
  • ceramic
  • Varying crystallinity and electron consumption in the ionic and covalent bonds cause most ceramic materials to be good thermal and electrical insulators (extensively researched in ceramic engineering). (wikipedia.org)
  • With such a large range of possible options for the composition/structure of a ceramic (e.g. nearly all of the elements, nearly all types of bonding, and all levels of crystallinity), the breadth of the subject is vast, and identifiable attributes (e.g. hardness, toughness, electrical conductivity, etc.) are hard to specify for the group as a whole.
