Interproximal Reduction
Interproximal reduction (IPR) (also called interproximal enamel reduction (IER) / slendering, air rotor stripping (ARS) or reproximation) is the practice of mechanically removing enamel from between the teeth to achieve orthodontic ends, such as to correct crowding, or reshape the contact area between neighboring teeth. After reducing the enamel, the procedure should also involve anatomic re-contouring and the protection of interproximal enamel surfaces. History In 1944, Murray L. Ballard was the first to advocate for the stripping of the lower anterior teeth due to crowding in a paper published in The Angle Orthodontist. Other authors, also advocated about slenderizing the teeth for next 40 years but it was not until 1980s when John J. Sheridan's Air Rotor Stripping technique for Interproximal Reduction captured society wide interest. He published two papers in the Journal of Clinical Orthodontics in which he explained his ARS technique. He stated that the procedure of IPR can ...

Tooth Enamel
Tooth enamel is one of the four major tissues that make up the tooth in humans and many other animals, including some species of fish. It makes up the normally visible part of the tooth, covering the crown. The other major tissues are dentin, cementum, and dental pulp. It is a very hard, white to off-white, highly mineralised substance that acts as a barrier to protect the tooth but can become susceptible to degradation, especially by acids from food and drink. Calcium hardens the tooth enamel. In rare circumstances enamel fails to form, leaving the underlying dentin exposed on the surface. Features Enamel is the hardest substance in the human body and contains the highest percentage of minerals (at 96%),Ross ''et al.'', p. 485 with water and organic material composing the rest.Ten Cate's Oral Histology, Nancy, Elsevier, pp. 70–94 The primary mineral is hydroxyapatite, which is a crystalline calcium phosphate. Enamel is formed on the tooth while the tooth develops wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orthodontics
Orthodontics is a dentistry specialty that addresses the diagnosis, prevention, management, and correction of mal-positioned teeth and jaws, and misaligned bite patterns. It may also address the modification of facial growth, known as dentofacial orthopedics. Abnormal alignment of the teeth and jaws is very common. Nearly 50% of the developed world's population, according to the American Association of Orthodontics, has malocclusions severe enough to benefit from orthodontic treatment: although this figure decreases to less than 10% according to the same AAO statement when referring to medically necessary orthodontics. However, conclusive scientific evidence for the health benefits of orthodontic treatment is lacking, although patients with completed orthodontic treatment have reported a higher quality of life than that of untreated patients undergoing orthodontic treatment. Treatment may require several months to a few years, and entails using dental braces and other appliances ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The Angle Orthodontist
''The Angle Orthodontist'' is a bimonthly peer-reviewed medical journal covering orthodontics that is published by the E. H. Angle Education and Research Foundation and is the official journal of the Edward H. Angle Society of Orthodontia. The editor-in-chief is Steven J. Lindauer (Virginia Commonwealth University). According to the ''Journal Citation Reports'', the journal has a 2014 impact factor of 1.225. History The journal was first formed in 1930 where Mrs. Angle became the first Editor-in-Chief and Dr. Frank A. Gough was the first Business Manager. The society was formed by the members of the Edward H. Angle Society of Orthodontia at their meeting in Chicago in 1930. Dr. Allan G. Brodie presented the first scientific paper of this journal. For the first 17 years, this was the only journal devoted strictly to orthodontia because American Journal of Orthodontics and Dentofacial Orthopedics journal was formerly known as American Journal of Orthodontia and Oral Surgery unt ...

Air Rotor Stripping
The atmosphere of Earth is the layer of gases, known collectively as air, retained by Earth's gravity that surrounds the planet and forms its planetary atmosphere. The atmosphere of Earth protects life on Earth by creating pressure allowing for liquid water to exist on the Earth's surface, absorbing ultraviolet solar radiation, warming the surface through heat retention (greenhouse effect), and reducing temperature extremes between day and night (the diurnal temperature variation). By mole fraction (i.e., by number of molecules), dry air contains 78.08% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and small amounts of other gases. Air also contains a variable amount of water vapor, on average around 1% at sea level, and 0.4% over the entire atmosphere. Air composition, temperature, and atmospheric pressure vary with altitude. Within the atmosphere, air suitable for use in photosynthesis by terrestrial plants and breathing of terrestrial animals is found only in Ea ...

Periodontal Disease
Periodontal disease, also known as gum disease, is a set of inflammatory conditions affecting the tissues surrounding the teeth. In its early stage, called gingivitis, the gums become swollen and red and may bleed. It is considered the main cause of tooth loss for adults worldwide.V. Baelum and R. Lopez, “Periodontal epidemiology: towards social science or molecular biology?,”Community Dentistry and Oral Epidemiology, vol. 32, no. 4, pp. 239–249, 2004.Nicchio I, Cirelli T, Nepomuceno R, et al. Polymorphisms in Genes of Lipid Metabolism Are Associated with Type 2 Diabetes Mellitus and Periodontitis, as Comorbidities, and with the Subjects' Periodontal, Glycemic, and Lipid Profiles Journal of Diabetes Research. 2021 Jan;2021. PMCID: PMC8601849. In its more serious form, called periodontitis, the gums can pull away from the tooth, bone can be lost, and the teeth may loosen or fall out. Bad breath may also occur. Periodontal disease is generally due to bacteria in the mout ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fluoride Varnish
Fluoride varnish is a highly concentrated form of fluoride which is applied to the tooth's surface, by a dentist, dental hygienist or other health care professional, as a type of topical fluoride therapy. It is not a permanent varnish but due to its adherent nature it is able to stay in contact with the tooth surface for several hours. It may be applied to the Tooth enamel, enamel, dentine or cementum of the tooth and can be used to help prevent decay, remineralise the tooth surface and to treat dentine hypersensitivity. There are more than 30 fluoride-containing varnish products on the market today, and they have varying compositions and delivery systems. These compositional differences lead to widely variable pharmacokinetics, the effects of which remain largely untested clinically. Fluoride varnishes are relatively new in the United States, but they have been widely used in western Europe, Canada, South Africa and the Scandinavian countries since the 1980s as a dental caries pre ...
