Dentist (other)
A dentist, also known as a dental doctor, dental physician, dental surgeon, is a health care professional who specializes in dentistry, the branch of medicine focused on the Human tooth, teeth, gums, and Human mouth, mouth. The dentist's Dental auxiliary, supporting team aids in providing oral health services. The dental team includes dental assistants, dental hygienists, dental technicians, and sometimes dental therapists. History Middle Ages In China as well as France, the first people to perform dentistry were barbers. They have been categorized into 2 distinct groups: guild of barbers and lay barbers. The first group, the Guild of Barbers, was created to distinguish more educated and qualified dental surgeons from lay barbers. Guild barbers were trained to do complex surgeries. The second group, the lay barbers, were qualified to perform regular hygienic services such as shaving and tooth extraction as well as basic surgery. However, in 1400, France made decrees prohibit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bachelor Of Dental Surgery
Dentistry, also known as dental medicine and oral medicine, is the branch of medicine focused on the teeth, gums, and mouth. It consists of the study, diagnosis, prevention, management, and treatment of diseases, disorders, and conditions of the mouth, most commonly focused on dentition (the development and arrangement of teeth) as well as the oral mucosa. Dentistry may also encompass other aspects of the craniofacial complex including the temporomandibular joint. The practitioner is called a dentist. The history of dentistry is almost as ancient as the history of humanity and civilization, with the earliest evidence dating from 7000 BC to 5500 BC. Dentistry is thought to have been the first specialization in medicine which has gone on to develop its own accredited degree with its own specializations. Dentistry is often also understood to subsume the now largely defunct medical specialty of stomatology (the study of the mouth and its disorders and diseases) for which reason ...

Pierre Fauchard
Pierre Fauchard (; 2 January 1679 – 21 March 1761) was a French physician, credited as being the "father of modern dentistry". He is widely known for writing the first complete scientific description of dentistry, ''Le Chirurgien Dentiste'' (''"The Surgeon Dentist"''), published in 1728. The book described basic oral anatomy and function, signs and symptoms of oral pathology, operative methods for removing decay and restoring teeth, periodontal disease ( pyorrhea), orthodontics, replacement of missing teeth, and tooth transplantation. Biography Early years Fauchard was born in a modest home in Saint-Denis-de-Gastines in 2 January 1679. In 1693 he joined the French Royal Navy at the age of 14, much to his family's distress, and came under the influence of Alexander Poteleret, a surgeon major, who had spent considerable time studying diseases of the teeth and mouth. During that time, Fauchard learned that sailors who were on long voyages suffered severely from dental ailm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crown (dentistry)
In dentistry, a crown or a dental cap is a type of dental restoration that completely caps or encircles a Human tooth, tooth or dental implant. A crown may be needed when a large dental cavity threatens the health of a tooth. Some dentists will also finish root canal treatment by covering the exposed tooth with a crown. A crown is typically bonded to the tooth by dental cement. They can be made from various materials, which are usually fabricated using ''indirect methods''. Crowns are used to improve the strength or appearance of teeth and to halt deterioration. While beneficial to dental health, the procedure and materials can be costly. The most common method of crowning a tooth involves taking a dental impression of a tooth prepared by a dentist, then fabricating the crown outside of the mouth. The crown can then be inserted at a subsequent dental appointment. This ''indirect method'' of tooth restoration allows use of strong dental restorative materials, restorative material ...

Dentures
Dentures (also known as false teeth) are prosthetic devices constructed to replace missing teeth, supported by the surrounding soft and hard tissues of the oral cavity. Conventional dentures are removable ( removable partial denture or complete denture). However, there are many denture designs, some of which rely on bonding or clasping onto teeth or dental implants ( fixed prosthodontics). There are two main categories of dentures, the distinction being whether they fit onto the mandibular arch or on the maxillary arch. Medical uses Dentures can help people via: * Mastication: chewing ability is improved by the replacement of edentulous (lacking teeth) areas with denture teeth. * Aesthetics: the presence of teeth gives a natural appearance to the face, and wearing a denture to replace missing teeth provides support for the lips and cheeks and corrects the collapsed appearance that results from the loss of teeth. * Pronunciation: replacing missing teeth, especially the ...

Dental Braces
Dental braces (also known as orthodontic braces, or simply braces) are devices used in orthodontics that align and straighten Human tooth, teeth and help position them with regard to a person's bite, while also aiming to improve dental health. They are often used to correct Malocclusion, underbites, as well as malocclusions, overbites, open bites, gaps, deep bites, cross bites, crooked teeth, and various other flaws of the teeth and jaw. Braces can be either cosmetic or structural. Dental braces are often used in conjunction with other orthodontic appliances to help widen the palate or jaws and to otherwise assist in shaping the teeth and jaws. Braces are an orthodontic device. They are to make the teeth straight, and to correct problems in a person's bite. There are many natural problems which occur to the way teeth fit together, but not everyone needs or will need braces. However, the use of braces is quite common, even when they are not medically necessary. Their cosmetic use f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bridge (dentistry)
A bridge is a fixed dental restoration (a fixed dental prosthesis) used to replace one or more missing teeth by joining an artificial tooth definitively to adjacent teeth or dental implants. Definitions Fixed bridge: A dental prosthesis that is definitively attached to natural teeth and replaces missing teeth. Abutment: The tooth that supports and retains a dental prosthesis. Pontic: The artificial tooth that replaces a missing natural tooth. Retainer: The component attached to the abutment for retention of the prosthesis. Retainers can be major or minor. Unit: Pontics and abutment teeth are referred to as units. The total number of units in a bridge is equal to the number of pontics plus the number of abutment teeth. Saddle: The area on the alveolar ridge which is edentulous where at least one missing tooth is to be reinstated. Connector: Joins the pontic to the retainer or two retainers together. Connectors may be fixed or movable. Span: The length of the alveo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dental Restorations
Dental restoration, dental fillings, or simply fillings are treatments used to restore the function, integrity, and morphology of missing tooth structure resulting from caries or external trauma as well as the replacement of such structure supported by dental implants. They are of two broad types—''direct'' and ''indirect''—and are further classified by location and size. Root canal therapy, for example, is a restorative technique used to fill the space where the dental pulp normally resides and are more hectic than a normal filling. History In Italy evidence dated to the Paleolithic, around 13,000 years ago, points to bitumen used to fill a tooth and in Neolithic Slovenia, 6500 years ago, beeswax was used to close a fracture in a tooth. Graeco-Roman literature, such as Pliny the Elder's Naturalis Historia (AD 23–79), contains references to filling materials for hollow teeth.

Toothpaste
Toothpaste is a paste or gel dentifrice that is used with a toothbrush to clean and maintain the aesthetics of Human tooth, teeth. Toothpaste is used to promote oral hygiene: it is an abrasive that aids in removing dental plaque and food from the teeth, assists in suppressing halitosis, and delivers active ingredients (most commonly fluoride) to help prevent tooth decay (dental caries) and gum disease (gingivitis).American Dental Association Description of Toothpaste Due to variations in composition and fluoride content, not all toothpastes are equally effective in maintaining oral health. The decline of tooth decay during the 20th century has been attributed to the introduction and regular use of fluoride-containing toothpastes worldwide. Large amounts of swallowed toothpaste can be poisonous. Common colors for toothpaste include white (sometimes with colored stripes or green tint) and blue. History Early toothpastes Since 5000 BCE, the Egyptians made a tooth powder, which cons ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Water Fluoridation
Water fluoridation is the controlled addition of fluoride to Public water supply, public water supplies to reduce tooth decay. Fluoridated water maintains fluoride levels effective for cavity prevention, achieved naturally or through supplementation. In the mouth, fluoride slows tooth enamel Demineralization (physiology), demineralization and enhances remineralization in early-stage cavities. Defluoridation is necessary when natural fluoride exceeds recommended limits. The World Health Organization (WHO) recommends fluoride levels of 0.5–1.5 mg/L, depending on climate and other factors. In the U.S., the recommended level has been 0.7 mg/L since 2015, lowered from 1.2 mg/L. Bottled water often has unknown fluoride levels. Tooth decay affects 60–90% of schoolchildren worldwide. Fluoridation reduces cavities in children, with Cochrane (organisation), Cochrane reviews estimating reductions of 35% in baby teeth and 26% in permanent teeth when no other fluoride s ...
