Georgetown University School Of Dentistry
The Georgetown University School of Dentistry was the dental school of Georgetown University, located in Washington, D.C. The school was established in 1901 as a department of the School of Medicine and became a standalone school within the university in 1956. In 1987, the school stopped accepting new students and it graduated its last class in 1990. History Origins The dental program was formed in 1901, during the presidency of Jerome Daugherty, with the acquisition by Georgetown of the Washington Dental College and the Hospital of Oral Surgery on Massachusetts Avenue. The Washington Dental College was incorporated into the School of Medicine as the dental department. There were initially five faculty chairs of: techniques and orthodontia; dental histology and pathology; operative dentistry; oral surgery; and prosthetic dentistry. Dr. William N. Cogan was elected as the school's first dean. In 1920, the first X-ray machine was installed in the dental department. The ...

Water Fluoridation
Water fluoridation is the controlled adjustment of fluoride to a public water supply solely to reduce tooth decay. Fluoridated water contains fluoride at a level that is effective for preventing cavities; this can occur naturally or by adding fluoride. Fluoridated water operates on tooth surfaces: in the mouth, it creates low levels of fluoride in saliva, which reduces the rate at which tooth enamel demineralizes and increases the rate at which it remineralizes in the early stages of cavities. Typically a fluoridated compound is added to drinking water, a process that in the U.S. costs an average of about $ per person-year. Defluoridation is needed when the naturally occurring fluoride level exceeds recommended limits. In 2011, the World Health Organization suggested a level of fluoride from 0.5 to 1.5 mg/L (milligrams per litre), depending on climate, local environment, and other sources of fluoride. Bottled water typically has unknown fluoride levels. Tooth decay rem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Study Abroad In The United States
Studying abroad in the United States is the act of a student pursuing educational opportunities in the United States. This can include primary, secondary and post-secondary students. Studying abroad is determined in the United States by political rationales of national security and foreign policy. The number of students studying abroad represents only about 1% of all students enrolled at institutions of higher education in the United States. While the majority of foreign students who study in the United States are pursuing a full degree, most outgoing U.S. students study abroad for one or two academic terms. The majority of US students now choose short-term study abroad programs according to the most recent Institute of International Education Open Doors Report. In the 2008–09 academic year, the five countries US students chose to study abroad in most were the United Kingdom, Italy, Spain, France, and China.

Clinic
A clinic (or outpatient clinic or ambulatory care clinic) is a health facility that is primarily focused on the care of outpatients. Clinics can be privately operated or publicly managed and funded. They typically cover the primary care needs of populations in local communities, in contrast to larger hospitals which offer more specialised treatments and admit inpatients for overnight stays. Most commonly, the English word clinic refers to a general practice, run by one or more general practitioners offering small therapeutic treatments, but it can also mean a specialist clinic. Some clinics retain the name "clinic" even while growing into institutions as large as major hospitals or becoming associated with a hospital or medical school. Etymology The word ''clinic'' derives from Ancient Greek ''klinein'' meaning to slope, lean or recline. Hence ''klinē'' is a couch or bed and ''klinikos'' is a physician who visits his patients in their beds. In Latin, this became ''clī ...

Dental Assistant
Dental assistants are members of the dental team. They support a dental operator (such as a dentist or other treating dental auxiliary) in providing more efficient dental treatment. ''Dental assistants'' are distinguished from other groups of dental auxiliaries (such as dental therapists, dental hygienists and dental technicians) by differing training, roles and patient scopes. History The first dental assistant C. Edmund Kells, a pioneering dentist operating from New Orleans, enlisted the first dental assistant. The dental field was initially dominated by males, but after this first addition of a female, it was then acceptable for women to seek dental treatment without their husbands. This led to dental assistants of that era also being known as "Ladies in Attendance". Thanks to the addition of women to dentistry, the profession flourished with more and more women seeking treatment and more patients overall receiving care. The first association It was not until almo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
