Pierre Fauchard (French pronunciation: [pjɛʁ foʃaʁ]; 2 January 1679 – 21 March 1761) [1] was a French physician, credited as being the "father of modern dentistry". [2] He is widely known for writing the first complete scientific description of dentistry, Le Chirurgien Dentiste ("The Surgeon Dentist"), published in 1728. [2]
Charles Stent (1807–1885) was a 19th-century English dentist notable for his advances in the field of denture making.. In 1847, English dentist Edwin Truman (1819–1905) introduced gutta-percha as a material for making dental impressions; however, this was unsatisfactory for several reasons, including its tendency to distort upon removal from the patient's mouth, and to shrink upon cooling.
During takeoff, ground effect can cause the aircraft to "float" while below the recommended climb speed. The pilot can then fly just above the runway while the aircraft accelerates in ground effect until a safe climb speed is reached. [2] For rotorcraft, ground effect results in less drag on the rotor during hovering close to the ground. At ...
Despite the limitations of the primitive surgical instruments during the late 17th and early 18th century, Fauchard was a highly skilled surgeon who made remarkable improvisations of dental instruments, often adapting tools from watchmakers, jewelers and even barbers, that he thought could be used in dentistry. He introduced dental fillings as ...
Alexander Martin Lippisch (2 November 1894 – 11 February 1976) was a German aeronautical engineer, a pioneer of aerodynamics who made important contributions to the understanding of tailless aircraft, delta wings and the ground effect, and also worked in the U.S.
He studied dentistry in Geneva, Switzerland and the Philadelphia Dental College, eventually becoming a dentistry professor at the University of Zurich. [17] At the time, it was still believed that dentine hypersensitivity was caused by either nerve fibre stimulation within dentine or odontoblast processes acting as pain receptors .
Dental sealants were first introduced as part of the preventative programme, in the late 1960s, in response to increasing cases of pits and fissures on occlusal surfaces due to caries. [9] This led to glass ionomer cements to be introduced in 1972 by Wilson and Kent as derivative of the silicate cements and the polycarboxylate cements. [5]
The exact mechanism of anesthetic effect from ZOE was not revealed perfectly, but possibly through anti-inflammatory effect, modulating immune cells to less inflamed status. [7] It is sometimes used in the management of dental caries as a "temporary filling". ZOE cements were introduced in the 1890s.
