John Tomes
Sir John Tomes (21 March 1815 – 29 July 1895) was an English dental surgeon. Life The eldest son of John Tomes and Sarah, his wife, daughter of William Baylies of Welford-on-Avon, then in Gloucestershire, he was born at Weston-on-Avon in Gloucestershire on 21 March 1815. He was articled in 1831 to Thomas Furley Smith, a medical practitioner in Evesham, and in 1836 he entered the medical schools of King's College, London and the Middlesex Hospital, at that time united. He was house surgeon to the Middlesex Hospital during 1839–40. Research with Madder on histology of bone and teeth brought Tomes to the notice of Sir Thomas Watson and James Moncrieff Arnott, who advised him to concentrate on dental surgery. He was admitted a member of the College of Surgeons of England on 21 March 1839, and in 1840 he went into practice at 41 Mortimer Street (now Cavendish Place). He was also preoccupied with the question of general anæsthesia, shortly after the introduction of ether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tomes's Process
Tomes's processes (also called Tomes processes) are a histology, histologic landmark identified on an ameloblast, cells involved in the production of tooth enamel. During the synthesis of enamel, the ameloblast moves away from the Tooth enamel, enamel, forming a projection surrounded by the developing enamel. Tomes's processes are those projections and give the ameloblast a "picket-fence" appearance under a microscope. They are located on the secretory, basal, end of the ameloblast. Terminal bar apparatuses connect the Tomes's processes. Tonofilaments separate the developing enamel from the enamel organ. Gap junctions synchronize cell activation. The body of the cell between the processes first deposits enamel, which will become the periphery of the enamel prisms, then the Tomes's process will infill the main body of the enamel prism. More than one ameloblast contributes to a single prism. Tomes's processes are distinctly different from Tomes's fibers, which are odontoblastic pr ...

Tomes's Fibers
An odontoblast process (also called Tomes's fibers or Tomes fibers, or by a dated term Tomes's fibrils) is an extension of a cell called an odontoblast, which forms dentin in a tooth. The odontoblast process is located in dentinal tubules. It forms during dentinogenesis and results from a part of the odontoblast staying in its location as the main body of the odontoblast moves toward the center of the tooth's pulp. The odontoblast process causes the secretion of hydroxyapatite crystals and mineralization of the matrix secreted by the odontoblasts.

Dentine
Dentin () (American English) or dentine ( or ) (British English) ( la, substantia eburnea) is a calcified tissue of the body and, along with enamel, cementum, and pulp, is one of the four major components of teeth. It is usually covered by enamel on the crown and cementum on the root and surrounds the entire pulp. By volume, 45% of dentin consists of the mineral hydroxyapatite, 33% is organic material, and 22% is water. Yellow in appearance, it greatly affects the color of a tooth due to the translucency of enamel. Dentin, which is less mineralized and less brittle than enamel, is necessary for the support of enamel. Dentin rates approximately 3 on the Mohs scale of mineral hardness. There are two main characteristics which distinguish dentin from enamel: firstly, dentin forms throughout life; secondly, dentin is sensitive and can become hypersensitive to changes in temperature due to the sensory function of odontoblasts, especially when enamel recedes and dentin channels become ...

Philosophical Transactions
''Philosophical Transactions of the Royal Society'' is a scientific journal published by the Royal Society. In its earliest days, it was a private venture of the Royal Society's secretary. It was established in 1665, making it the first journal in the world exclusively devoted to science, and therefore also the world's longest-running scientific journal. It became an official society publication in 1752. The use of the word ''philosophical'' in the title refers to natural philosophy, which was the equivalent of what would now be generally called ''science''. Current publication In 1887 the journal expanded and divided into two separate publications, one serving the physical sciences ('' Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences'') and the other focusing on the life sciences ('' Philosophical Transactions of the Royal Society B: Biological Sciences''). Both journals now publish themed issues and issues resulting from pap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Society Of Arts
The Royal Society for the Encouragement of Arts, Manufactures and Commerce (RSA), also known as the Royal Society of Arts, is a London-based organisation committed to finding practical solutions to social challenges. The RSA acronym is used more frequently than the full legal name (The Royal Society for the Encouragement of Arts, Manufactures and Commerce). The RSA's mission expressed in the founding charter was to "embolden enterprise, enlarge science, refine art, improve our manufacturers and extend our commerce", but also of the need to alleviate poverty and secure full employment. On its website, the RSA characterises itself as "an enlightenment organisation committed to finding innovative practical solutions to today's social challenges".

Dental Key
The dental key is an instrument that was used in dentistry to extract diseased teeth. Before the era of antibiotics, dental extraction was often the method of choice to treat dental infections, and extraction instruments date back several centuries. History The dental key, (also known as Clef de Garengeot, Fothergill-Key, English-Key, Dimppel Extractor or Tooth Key) was first mentioned in Alexander Monro's ''Medical Essays and Observations'' in 1742, but had probably been in use since around 1730. It remained popular into the 20th century when it was replaced by the more modern forceps. Design and use Modeled after a door key, the dental key was used by first inserting the instrument horizontally into the mouth, then its "claw" would be tightened over a tooth. The instrument was rotated to loosen the tooth. This often resulted in the tooth breaking, causing jaw fractures and soft tissue damage. The design of the dental key evolved over the years. The original design fea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Golden Wedding
A wedding anniversary is the anniversary of the date a wedding took place. Couples may take the occasion to celebrate their relationship, either privately or with a larger party. Special celebrations and gifts are often given for particular anniversary milestones (e.g. 10, 15, 20, 25 years). In some cultures, traditional names exist for milestone anniversaries; for instance, fifty years of marriage may be known as a "golden wedding anniversary", "golden anniversary" or "golden wedding". Recognition Celebrating wedding anniversaries as ''gold'' (50 years) or ''silver'' (25 years) is documented in Germanic countries since the 1500s. In the twentieth century, commercialism led to the celebration of more anniversaries according to a list of predetermined gifts. In some parts of the world, couples can receive special recognition from government officials for particular milestones. In the Commonwealth realms, one can receive a message from the monarch for 60th, 65th, and 70th wedding ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surrey
Surrey () is a ceremonial and non-metropolitan county in South East England, bordering Greater London to the south west. Surrey has a large rural area, and several significant urban areas which form part of the Greater London Built-up Area. With a population of approximately 1.2 million people, Surrey is the 12th-most populous county in England. The most populated town in Surrey is Woking, followed by Guildford. The county is divided into eleven districts with borough status. Between 1893 and 2020, Surrey County Council was headquartered at County Hall, Kingston-upon-Thames (now part of Greater London) but is now based at Woodhatch Place, Reigate. In the 20th century several alterations were made to Surrey's borders, with territory ceded to Greater London upon its creation and some gained from the abolition of Middlesex. Surrey is bordered by Greater London to the north east, Kent to the east, Berkshire to the north west, West Sussex to the south, East Sussex to ...

Caterham
Caterham () is a town in the Tandridge District of Surrey, England. The town is administratively divided into two: Caterham on the Hill, and Caterham Valley, which includes the main town centre in the middle of a dry valley but rises to equal heights to the south. The town lies close to the A22, from Guildford and south of Croydon, in an upper valley cleft into the dip slope of the North Downs. Caterham on the Hill is above the valley to the west. History An encampment on the top of White Hill, in Caterham Valley south of Caterham School, between Bletchingley and the town centre is called ''The Cardinal's Cap'' which was excavated and inspected in designating it a Scheduled Ancient Monument. With close ramparts forming two or more lines, archaeologists describe the fort as a "large multivallate hillfort at War Coppice Camp". The town lies within the Anglo-Saxon feudal division of Tandridge hundred. Post Norman Conquest Caterham's church of St Lawrence is of Nor ...

Dentists Act 1878
A dentist, also known as a dental surgeon, is a health care professional who specializes in dentistry (the diagnosis, prevention, management, and treatment of diseases and conditions of the oral cavity and other aspects of the craniofacial complex including the temporomandibular joint). The dentist's 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. Ho ...
