Dental assistant
Dental assistants are members of the dental team. They may support a dental operator in providing more efficient dental treatment. Dental assistants are distinguished from other groups of dental auxiliaries by differing training, roles and patient scopes.
History
The first dental assistant
The first dental assistant in modern history is believed to trace back to 1885. Dr Edmund Kells, a pioneering dentist operating from New Orleans, enlisted the help of his wife, Malvina Cueria to assist him during dental procedures. 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 almost four decades later that in 1923 the first dental assistant association was founded by Juliette Southard, named the American Dental Assistant Association and it is still in practise now. It began with just five members, now reaching more than 10,000.Roles
The dental assistant's role is often thought to be to support the dental operator by typically passing instruments during clinical procedures. However, in fact, their role extends much further to include: providing patients help with their oral hygiene skills, preparing the patient for treatment, sterilising instruments, assisting during general anaesthetic dental procedures, positioning suction devices, exposing dental radiographs, taking dental impressions, recording patient notes and administration roles such as scheduling appointments.Infection control
It was customary for oral health care workers and dental assistants in the 1980s to practice oral health care without wearing gloves, masks or eye protection. This was at a crucial time due to the human immunodeficiency virus spreading rapidly at a global rate. However, in 2018 gloves, masks and eye protection have become part of the standard infection control guidelines which has been implemented in all oral health care settings as a means of preventing the spread of infectious disease. Infection control in oral health care not only protects the patient but it also protects the oral health care workers. This includes: dentists, dental specialists, oral health therapists, dental hygienists and dental assistants.Dental assistants play a crucial role in maintaining high levels of infection control in the oral health care setting. The dental assistant is the major link between oral health care workers and the patient. To perform infection control responsibilities well, the dental assistant must have the appropriate education, training and work experience. Examples of infection control protocols that the dental assistant needs to follow in an oral health setting include:
Hand hygiene
aims to reduce the number of microorganisms on hands. Antimicrobial agents such as alcohol-based hand rub or antimicrobial soap and water are effective agents to remove most antimicrobial bacteria on hands in dental settings.Personal protective equipment (PPE)
Gloves, gown and eye protection are essential barrier protection items that enable the dental assistant to reduce the transmission of infectious diseases to themselves, other dental co-workers and patients. Gloves and masks need to be disposed after each patient, eyewear can be disposable or reusable and gowns need to be replaced if visibly soiled. Lastly, footwear must include leather closed toe shoes; this minimises the risk of sharps injury.Surgical procedures and aseptic technique
It is crucial to wear sterile gloves when the dental assistant is assisting in surgery with the oral health care clinician. Hand hygiene using antimicrobial soap and water is imperial to maintaining adequate infection control in this setting, as this minimises the risk of infection.Management of sharps injury
It is crucial that sharp instruments which include: needles, scalers, scalpels, burs, orthodontics bands and endodontic files need to be handled with care and appropriate techniques to minimise any potential sharps injury. Sharps also need to be disposed accordingly into the sharps containers, separate from other disposable bins. The dental assistant needs to be aware of what is required to go into the sharps containers and what is not. This minimises the chance of spreading infectious diseases.Management of clinical waste
It is imperative that when performing change over, that the dental assistant is able to distinguish the difference between medical related waste compared to contaminated waste. Contaminated waste needs to be placed in a leak proof thick yellow bag with a biohazard symbol label.Environment
The dental assistant should put on new gloves when cleaning working surfaces during the changeover between patients. They must also be able to distinguish between clean and dirty zones as this minimises the spread of infectious diseases between co-workers and patients. Additionally, plastic barriers are placed on: instruments such as; hand pieces connected to the chair, overhead lights, amalgamators, x-ray machines, mixing materials and other miscellaneous dental instruments, materials or appliances. One of the roles that the dental assistant participates in is changing these plastic barriers after each patient has left that surgery. This ensures that the surgery is set up ready for the next patient.- These infection control procedures and protocols not only apply to the dental assistant, but to all co-workers in the oral health care setting. However, the dental assistant is the major connection between the patient and the oral health care clinician. Therefore, it is imperative that they follow these guidelines to minimise the risk of spreading possible infectious diseases to co-workers, patients and themselves.
Sterilisation, disinfectant and antiseptic
- Autoclaving where moist heat kills bacteria by denaturation of high protein- containing bacteria at 250F for 15 to 20 minutes or 270 F for 3 minutes. Biological monitors and Process indicators are 2 methods used to ensure the effectiveness of sterilization process.
- # Biological monitor where bacterial spores are placed in strips or envelops along with the instruments. This method shows that the microorganisms have been eradicated and must be conducted weekly.
- # Process indicators; where the load has reached a certain temperature, the indicators change their colour.
- Dry heat sterilization which requires a higher temperature and longer time than steam autoclave, therefore, only glass or metal objects can be steamed by dry heat.
- Chemiclave by using Ethylene oxide at relatively low temperature for 2–3 hours.
- Cold/ chemical test which can be done by soaking instruments in a specific chemical solution such as 2% glutaraldehyde for 10 hours in order to kill bacterial spores. However, this method does not destroy hepatitis viruses and spores.
Health promotion
Dental assistants make a difference in the community by participating in health promotion activities and programs. These programs may take place at schools, preschools, immunisation events or at maternal health clinics. Dental operators may also be supported by dental assistants during pre-school or school screenings.Dental assistants can extend their scope to provide oral health promotion to patients in Australia by completing the Certificate IV in Dental Assisting. The dental assistant will have the ability to implement an individualised oral health promotion program and oral hygiene program. After the appropriate training the dental assistant may;
- Promote the dental team concept in achieving good oral health and promoting good oral hygiene habits
- Assist in making dental treatment accessible and affordable to the community
- Perform health promotion activities by promoting good oral health to the community
- Support and educate on oral health promotion to allied health professionals
- Residential Aged Care Facilities
- Special Needs
- Schools
- Early childhood services
- Culturally diverse communities
- Community sport clubs
- Oral diseases
- Diet analysis and counselling
- Oral hygiene strategies
- Preventive strategies
- Care of fixed & removable prosthesis and fixed appliances
- Smoking cessation
- Preventing sports injuries
Radiography
Upon successful completion of the training program dependent on the course structure, the dental assistant may:
Expose intra-oral radiographs that ensures an optimum radiographic image.
Process, mount and file intra-ora l radiographs. - Able to identify technical faults
and their causes. - Be able to demonstrate an understanding of potential hazards of exposure to radiation and to practice high standards of radiation therapy.
- To recognise normal anatomy.
- Maintain infection control throughout all practical procedures.
Potential future roles
Aging population
Looking to the future of dentistry and oral health, the roles for dental assistants are ever-changing and expanding. With the increase in an ageing population, it will become more and more commonplace for dental assistants to be employed to support dental operators with providing oral health promotion and treatment within residential care facilities.Increasing demand to match new dental graduates
The number of newly graduated dentists and dental auxiliaries is increasing and with that the need for dental assistants. According to the Bureau of Labor Statistics of America the rate of employed dental assistants will likely increase by 18% in the ten years between 2014 and 2024. With an increase in dental assistants comes the possibility of extension in the dental assistant roles and scope. As seen in some states of the United States of America, dental assistants are able to perform some simple fillings with the supervision of a practising dentist. By allowing dental assistants to extend their scope alongside the appropriate training, the workload of the other members of the dental team is lessened and increases efficiency of the dental clinic management. This may have the potential to reach other countries in the future as the need for dental and oral health treatments increase.Variations around the world
Dental assistant roles can vary depending on different country qualifications and regulations. Below are examples of dental assisting roles which the dental assistant is able to perform, respective to that country.Australia

Australian Dental assistants perform limited and restricted duties and are not permitted to perform any of the following:
- any irreversible procedure on the human teeth or jaw or associated structures
- correcting malpositions of the human teeth or jaw or associated structures;
- fitting or intra-orally adjusting artificial teeth or corrective or restorative dental appliances for a person
- performing any irreversible procedure on, or the giving of any treatment or advice to, a person that is preparatory to or for the purpose of fitting, inserting, adjusting, fixing, constructing, repairing or renewing artificial dentures or a restorative dental appliance
There is no formal training required of entry level dental assistants in order to commence or undertake work in private practice in Australia. Most dental assistants gain practical experience at a place of employment although there are vocational qualifications which are nationally recognised and highly recommended for increasing a person's job prospects, remuneration, and professional development.
The National Vocational Qualification HLT35015 Certificate III in Dental Assisting is the entry level of vocational training for dental assisting while HLT45015 Certificate IV in Dental Assisting are suitable for those who seek to further their skills and duties and elect units from particular streams such as dental radiography, oral health promotion, practice administration, general anaesthesia and conscious sedation. These formal qualifications can be offered only by registered training organisations such as TAFE and professional associations while Certificate III in Dental Assisting may also be offered as a traineeship in most States of Australia and as a School-based Traineeship for years 11 and 12 in some States.
Currently dental assistants are not required to be registered under the Dental Board of Australia or with any State and Territory Boards since dental assisting is not a registered profession. Dental Assistants who have attained a Certificate IV in Dental Assisting – Dental Radiography and are required to operate dental radiography apparatus as part of their job role, must hold a current license with the relevant state or territory Radiation Authority.
Dental assistants are strongly encouraged to have current vaccinations for Hepatitis B, and Tetanus along with the normal childhood vaccination recommendations and influenza. Many state and territory public health care facilities and training providers will require students and workers to present evidence of Hepatitis B immunity and the results of a criminal history check prior to commencing clinical placement. Most private dental clinics will also require employees to have current vaccination records and may also require workers to undertake annual influenza vaccinations.

The Commission on Dental Accreditation of the American Dental Association accredits dental assisting school programs, of which there are over 200 in the United States.
To become a Certified Dental Assistant, or CDA, dental assistants must take the DANB CDA examination after they have completed an accredited dental assisting program, while those who have been trained on the job or have graduated from non-accredited programs are eligible to take the national certification examination after they have completed two years of full-time work experience as dental assistants. Some dentists are willing to pay a dental assistant-in-training that has a good attitude and work ethic.
In the USA the Dental Assisting National Board offers three nationally recognised certifications, namely:
- Certified Dental Assistant
- Certified Orthodontic Assistant
- Certified Preventative Functions Dental Assistant
Duties may also include seating and preparing the patient, charting, mixing dental materials, providing patient education and post-operative instructions. They also keep track with inventory control and ordering supplies.
