A dental therapist is a member of the dental team whose role is dependent on their approved education, training and competence.  The age of patient's they are able to treat, whether it be children, adolescents, or adults is also dependent on their training. However their main role in the dental team is the provision of preventative services.  This page will explore the Australian and other various countries that employ dental therapists. This includes information on their training, responsibilities, roles within the dental team, and history.
Local dental regulations are constantly changing to include extended duties and exemptions for dental therapists, with each country having their own regulations and guidelines.
Dental Therapists provide preventative and restorative dental care for children and adolescents in fifty three countries, below are a select few that sufficient and appropriate information was able to be obtained about.
Dental Therapist Training in Australia
Dental therapists are no longer trained in Australia, and instead Oral Health Therapists are being trained. An oral health therapist is trained as both a dental therapist and a dental hygienist with a focus on health promotion and disease prevention.
Oral health therapy training occurs at university level and therefore completion of secondary schooling to a high standard is mandatory, including certain pre-requisite subjects that differ between states/territories and between the universities that offer the courses themselves. This specific information can be found at http://www.jobguide.thegoodguides.com.au/occupation/Oral-Health-Therapist 
The training varies, depending on what is offered at each university, but the golden rule is that once graduated an oral health therapist can only perform what they have been formally trained in.  
Oral Health Therapists are trained to perform:
• Educate and motivate children and the community
• Dental examinations
• Cleaning teeth
• Restoring teeth
• Local anaesthetic
• Extracting deciduous (baby) teeth
• Taking radiographs (x-rays)
• Preventative treatments – fissure sealants, fluoride applications, oral hygiene instruction
• Taking impressions for mouthguards
• Refer complex problems to dentists
• Educate school canteens about health foods
• Liase with other health care professionals
Dental Therapist Training in New Zealand
Development of the Dental Therapists began in New Zealand, they were initially trained as “Dental Nurses” providing preventative and simple restorative care to children aged up to 12 years old. Dental Therapists in New Zealand were employed to treat children at a school dental service including treatment of pre-school children.
Dental Therapist Training in United Kingdom
Training can be obtained through two courses, a combined Dental Hygiene and Therapy 27 month (full-time) course or a Bachelors in Oral Health Science 3 year (full-time) course, once qualified a therapist must be registered with the General Dental Council. Before treatment can occur through the provision of a therapist, a qualified dentist must perform the initial examination. The procedures performed by dental therapists in the UK include routine and preventative treatment and education with patients. The therapists have a large focus on patients self care creating home care plans and identifying areas where patients express deficits in efficacy of plaque removal. Dental therapists in the UK are majorly employed into the community dental profession and perform a limited range of treatment. Some of the procedures carried out by UK dental therapists include examinations, taking radiographs (x-rays), simple fillings, implementing preventative strategies (fluoride application, dental sealants (fissure seals), oral hygiene instruction) and dental health education 
Dental Therapist Training in the United States
The United States are increasing employment and training opportunities for dental therapists in order to reduce to the level of need and to increase access to care for Americans. Alaska and Minnesota are the two main states that are advocating dental therapists into their communities. These dental therapists can perform a number of basic clinical dental treatment and preventative services under the general and indirect supervision of dentists. The Dental therapist as a member of the oral healthcare team can provide restorative dental treatment services, disease prevention and oral health promotion programs to maintain and improve oral health. These procedures include exposing radiographs/x-rays, administering local anaesthetic, administering nitrous oxide, application of topical preventative or prophylactic agents including fluoride varnishes and fissure sealants, preparations and restorations of primary and permanent teeth, repair of defective prosthetic devices, and recementing of permanent crowns.

Responsibilities of a Dental Therapist
Under the supervision of a dentist, in a private or public setting, a Dental therapist is allowed to examine, prevent and treat oral diseases in pre-school, primary and secondary school children . The following tasks are regularly performed by Dental Therapists.
- Educate patients, parents, schools and communities about the progression of dental disease, how to prevent dental disease and how to maintain good oral health.
- Treat patients via giving comprehensive oral examination, dietary advice, help to modify any risk factors for dental disease, give oral hygiene instruction to patient and parent/guardian, remove and fill Dental caries. Extract deciduous (baby) teeth under local anaesthetic, perform Pulpotomy treatment on indicated deciduous teeth, take radiographs of the patient’s teeth, provide Dental sealant protection when necessary, administer fluoride therapy and provide a professional clean.
- Refer and Communicate - Dental Therapists are able to refer to a dentist when a problem becomes complex, they work within schools, including canteens in recommending healthy options for students and staff. They can give oral hygiene instruction to classes and can communicate with other health care providers i.e. Immunisation clinics and maternal health care nurses.
Role within the dental team
Suggested edit under the role within the dental team section by Tristandfield The dental profession involves the study, diagnosis, prevention and treatment of diseases, disorders and conditions involving the oral cavity and surrounding structures. Dental therapists practice in a team situation alongside a practising dentist and have a tradition of being part of the dental team primarily to provide dental care to children through school dental services 
The dental therapists role in the dental team can include the provisions of oral health assessment, treatment planning, management and prevention for children, adolescents and adults, which is dependent on their training. In many practices dental therapists are limited to the provision of restorative dental care and extractions to those aged 25 and under, however there are some settings where the dental or oral health therapist can provide these services to someone of any age where the clinician has developed his or her scope of practice.
For around forty years in Australia, dental therapists have been practicing alongside dentists providing diagnostic, preventive, restorative and health promotion services to children and adolescents.
Common procedures performed by dental therapists include examination, prescribing and exposing intra and extra oral dental xrays, administration of local anaesthesia, preparation and restoration of carious lesions, pulpal therapies, extraction of deciduous teeth and preventive therapies such as fissure sealants and fluoride application. Oral health education and promotion also plays a large part in the dental therapists role.
Professional support for the role of the dental therapist in the dental team has been widely accepted in Australia and New Zealand, where their role came about in response to population need from the rising numbers of caries prevalence in children. This same support has not followed in all countries, with the United States referring to dental therapists as ‘lower level practitioners’ with a study showing 75% of US paediatric dentists not knowing what a dental therapist was and 71% of them disagreeing to add them as part of the dental team.
In 1913, the then President of the New Zealand Dental Association, Dr Norman K Cox proposed a system of school clinics operated by the state and staffed by 'oral hygienists' to address the dental needs of children between the ages of 6 and 14 years. At the time the idea was considered too unorthodox but in 1920, at a special meeting of the New Zealand Dental Association, 16 members voted for the adoption of school dental nurses with 7 opposed to the proposal. Such a drastic change in the voting could be accredited to the refusal of New Zealand troops during the first world war. The recruits were rejected due to rampant and uncontrolled dental diseases.
School dental nurses were to provide diagnostic and restorative services to children '...in a rigidly structured set of methods and procedures which spare her the anxiety of making choices'. In Great Britain, during the first world war, 'dental dressers' were used to carry out examinations and treatment for children in parts of England. Their role however, was eliminated by the Dentist Act of 1921 because of hostility to the role on the part of the dentist profession. They were later re-introduced, on the strength of the New Zealand scheme, as dental therapists when the high dental needs of children were 'rediscovered' in the 1960s, carrying out similar services but under the prescription of a dentist who carried out the examination and care plan.
The success of New Zealand's program was so significant that many countries facing similar needs adopted programs which mirrored the ones initially established in New Zealand. School dental services which followed similar training became popular in countries such as Canada, South Africa, the Netherlands (temporarily), Fiji, Hong Kong, Malaysia and the Philippines and in 2000, 28 countries around the world utilised dental therapists. In today's modern day practices, in all previously mentioned countries dental therapists are becoming more recognised and employable due to the identifiable need for dental professionals in undeserved areas.
