Dentistry is the practical application of knowledge of dental science (the science of placement, arrangement, function of teeth and their supporting bones and soft tissues) to human beings. A dentist is a doctor qualified to treat diseases, malformations of, and injuries to teeth, a professional practitioner of dentistry. In most countries, several years of training in a university (usually 4-8) and some practical experience working with actual patients' dentition are required to become a qualified dentist. The patron saint of dentists is Saint Apollonia, martyred in Alexandria by having all her teeth violently extracted, not, one would have thought, such a very desirable exemplar.

Specialties

Visits to the dentist are often feared or dreaded.

There are nine dental specialties recognized by the American Dental Association and require 2-6 years of further formal university training after dental school. The specialties are Dental Public Health (study of dental epidemiology and social health policies), Endodontics (root canal therapy), Oral and Maxillofacial Pathology (study, diagnosis, and often the treatment of oral and maxillofacial related diseases), Oral and Maxillofacial Radiology (study and radiologic interpretation of oral and maxillofacial diseases), Oral and Maxillofacial Surgery (extractions and facial surgery), Orthodontics (straightening of teeth), Pedodontics (pediatric dentistry; i.e. dentistry for children), Periodontics (treatment of gum disease), Prosthodontics (replacement of missing facial anatomy by prostheses such as dentures, bridges and implants).

Specialists in these fields are designated registrable (U.S. "Board Eligible") and warrant exclusive titles such as orthodontist, oral surgeon, pedodontist, periodontist, or prosthodontist upon satisfying certain local (U.S. "Board Certified") registry requirements.

Two other post-graduate formal advanced education programs: General Practice Residency (advanced clinical and didactic training with intense hospital experience) and Advanced Education in General Dentistry (advanced training in clinical dentistry) recognized by the ADA do not lead to specialization.

Other dental education exists where no post-graduate formal university training is required: cosmetic dentistry, dental implant, temporo-mandibular joint therapy. These usually require the attendance of one or more continuing education courses that typically last for one to several days. There are restrictions on allowing these dentists to call themselves specialists in these fields. The specialist titles are registrable titles and controlled by the local dental licensing bodies.

Forensic odontology consists of the gathering and use of dental evidence in law. This may be performed by any dentist with experience or training in this field. The function of the forensic dentist is primarily documentation and verification of identity.

Geriatric dentistry or gerodontics is the delivery of dental care to older adults involving the diagnosis, prevention, and treatment of problems associated with normal aging and age-related diseases as part of an interdisciplinary team with other health care professionals.

In 2001 archaeologists studying the remains of two men from Mehrgarh, Pakistan, made the discovery that the people of Indus Valley Civilization, even from the early Harappan periods (c. 3300 BC), had knowledge of medicine and dentistry. The physical anthropologist that carried out the examinations, Professor Andrea Cucina from the University of Missouri-Columbia, made the discovery when he was cleaning the teeth from one of the men (see History of medicine).

Some information contained in the Edwin Smith Papyrus dates as early as 3000 BC and includes the treatment of several dental ailments ([1] & [2]). The Ebers papyrus also discusses similar treatments ([3]). Examining the remains of some ancient Egyptians and Greco-Romans reveal early attempts at dental prosthetics and surgery ([4]).

Historically, dental extractions have been used to treat a variety of illnesses. During the middle ages and through the 19th century, dentistry was not a profession into itself, and often dental procedures were performed by barbers or general physicians. Barbers usually limited their practice to extracting teeth, which not only resulted in the alleviation of pain, but often cured a variety of ailments linked with chronic tooth infection. Instruments used for dental extractions date back several centuries. In the 14th century, Guy de Chauliac invented the dental pelican (resembling a pelican's beak) which was used through the late 18th century. The pelican was replaced by the dental key which, in turn, was replaced by modern forceps in the 20th century.

Dentistry throughout the world

Dentistry in Australia

In Australia, graduating dentists earn either a B.D.S. (Bachelor of Dental Surgery) or B.D.Sc (Bachelor of Dental Science) degree.

Regarded as the premier dentistry course in Australia, the B.D.Sc course at the University of Melbourne spans five years, pending an accumulation of both high school performance (Equivalent National Tertiary Entrance Rank (ENTER) score in Victoria or other national equivalent; International Bachelorette or any other International equivalent) and Undergraduate Medicine and Health Sciences Admission Test (UMAT) scores. Clinical practice during the course begins during year one at the Royal Dental Hospital of Melbourne, adjacent to the main campus of the University (and also to the Royal Women's Hospital). The first three years are mainly theoretically based in the wider aspect of health sciences including anatomy, biology, chemistry, microbiology, pathology, pharmacology and neuroscience. Significant clinical experience is gained right up until the fifth and final year, which consists almost completely of clinical work. BDSc at MU

Also spanning five years, the B.D.Sc offered by the University of Queensland (UQ) combines high-school performance with an in-person interview on campus. UMAT scores do not apply. It is unique to Australia as it involves a 1-3-1 program: undergraduates undertake one year of preliminary generalist science courses, followed by three years of theoretical and clinical-based theory at the dental school. It is concluded by one year of extra-mural studies in regional placements.

Dentistry in Canada

Canadian dentistry is overseen by the Canadian Dental Association, while specialization is overseen by the Royal College of Dentists. Today, Canada has about 16,000 dentists. Canadian dentistry is not publicly run (see Medicare (Canada)); only children and the elderly can have free dental care. Other Canadians are mostly covered by workplace dental plans, but many have to pay out of pocket.

For most of the early colonial period dentistry was a rare and unusual practice in Canada. In severe situations, barbers or blacksmiths would pull a tooth, but for many years Canada lagged behind European advances. The first dentists in Canada were United Empire Loyalists who fled the American Revolution. The first recorded dentist in Canada was a Mr. Hume who advertised in a Halifax newspaper in 1814.

During the first half of the 19th century, dentistry expanded rapidly. In 1867 the Ontario Dental Association was formed and in 1868 they founded Canada's first dental school in Toronto, the Royal College of Dental Surgeons of Ontario. The University of Toronto agreed to be affiliated with the dental school. As time passed, other Canadian universities also created dentistry programmes.

Dentistry in Hong Kong

The longest record for such ongoing and routine training and qualifying requirement for dental specialties in the world exists in Hong Kong where 5 years of pre-specialty, formal training and supervised practice are prescribed. It is accepted that only after 5 years of such training would the trainees achieve a superior level of professional competence.

Dentistry in India

Modern Indian dentists must earn the Bachelor of Dental Surgery degree (B.D.S.), which requires four years of study and one year of internship. This degree is overseen by the Dental Council of India. In most states, one has to appear for an entrance test conducted by the Directorate of Medical Education, whereas some autonomous universities conduct their own entrance tests.

Dentistry in Malaysia

In Malaysia, there are 3 universities currently offering dentistry course. The universities are Universiti Malaya, Universiti Kebangsaan Malaysia and Universiti Sains Malaysia, although many other Malaysian universities are showing interest in offering undergraduate course in dentistry in the future.

Dentists trained in Malaysia have to complete 5 years of undergraduate study (previously 4 years) before earning a B.D.S (Universiti Malaya) or a D.D.S (Universiti Kebangsaan Malaysia/Universiti Sains Malaysia). Undergraduates in Malaysia are required to spend the first 2 years in pre-clinical lectures and the next 3 years they are required to do clinical sessions as well as attending lectures.

Once graduated from the course, Malaysian dentists are required to serve the Malaysian Government for 3 years compulsory service, regardless where they completed their undergraduate study. They can choose to work under Kementerian Kesihatan (Ministry of Health) or Kementerian Pertahanan (Ministry of Defence) as a military dentist.

Dentistry in Pakistan

At present there are upwards of 20 dental schools (public & private) throughout Pakistan, according to the Pakistan Medical & Dental Council the state regulatory body has upwards of 6200 registered dentists. The four year training culminates in achieveing a Bachelor of Dental Surgery (BDS) degree, which also requires a one year compulsary interneship to be a registered dentist in Pakistan.

Dentistry in Slovakia

In Slovakia, dentists complete 6 years of undergraduate study to earn a MUDr (lat. Medicinae Universae Doctor) degree. Junior graduates work under a skilled doctor for at least 3 years to receive their license from The Slovak Chamber of Dentists.

Dentistry in the United Kingdom

In the United Kingdom, dentists complete 5 years of undergraduate study to earn a B.D.S. degree. After graduating most dentists will enter a V.T. (vocational training) scheme, of either 1 or 2 years length, to receive their full National Health Service registration. Dentists must register with the G.D.C. (General Dental Council), and meet their requirements as the governing body of the profession, before being allowed to practice.


Dentistry in the United States

In the United States, dentists earn either a D.D.S. (Doctor of Dental Surgery) or D.M.D.(Doctor of Dental Medicine) degree. There are 54 Accredited Dental schools in the United States requiring 4 years of post graduate study (except for one unique 3 year program at the University of the Pacific). Most applicants to dental school have attained at least a B.S. or B.A. degree, however, a small percentage are admitted after only fulfilling specific prerequisite courses. So unlike many other countries, it can take more then 8 years to become a dentist. ( List of U.S. dental schools) The degrees D.D.S. and D.M.D. require equivalent education and are identical in every way. The difference relates to the history involved in the division of medicine and surgery in medical practice. There has been a recent movement to include a 5th year of education that focuses on purely practical training in the clinical setting. In at least one state, a state dental license can be received without taking the licensing exam (State Board Exam) upon completing this additional year of training. Dentists are licensed and regulated by the state in which they practice. The license is only valid in the issuing state and is non-transferable. There are many cooperative agreements between states that allow recognition of another state's license so as to procure a license either via "licensure by credentials" or "licensure by reciprocity."

A dentist may go on for further training in a dental specialty which require an additional 1 to 7 years of post-doctoral training. There are 9 recognized dental specialties. They are Endodontics(root canal treatment), Oral and Maxillofacial Pathology, Oral and Maxillofacial Radiology, Pediatric Dentistry, Periodontics(gums), Prosthodontics(complicated dental reconstruction), Orthodontics(braces), Oral and Maxillofacial Surgery(tooth removal and surgery of the oral and related structures), and Dental Public Health. There is no specialty in esthetic dentistry or implantology, and no additional training is required for a dentist to make the claim of being an esthetic or cosmetic dentist.

Any general dentist may perform those procedures designated within the enumerated specialties if they deem themselves competent. Many general dentists train in certain aspects of the above specialties such as the placement and restoration of dental implants, advanced prosthodontics and endodontics, and have limited or heavily focused their practices to these areas. When a general dentist performs any procedure that falls within the realm of a specialty, they are expected to perform with the same level of expertise as a certified specialist and are legally held to such standards with respect to any issues of malpractice.

Dentistry in Italy

In Italy dentists complete 5 years of undergraduate study to earn a degree. Nevertheless it is possible to agree on certain basic clinical competences common to all member states of the European Union.

The following is an example of one such clinical competency (excision of a buried tooth root): If a clinician is deemed to be clinically competent in the surgercal removal of a buried root, this implies much more than the technical and surgical ability required to excise a buried piece of root from alveolus. It embraces a broad range of preclinical and clinical knowledge and understanding on which surgical treatment is based.
