A registered dental assistant can practice in the field even without the professional degree in dentistry. A dental assistant is actually a person who helps and assists the dentists in their clinics and hospice practices to ensure a good and efficient dental treatment. His duty is to perform all the non-specialized tasks to make the treatment successful. They are actually appointed by the dentists to do the things like fixing the apparatuses, preparing the patient with goggles, cleaning and sterilizing instruments, passing instruments throughout the modus operandi and carrying a suction device. He is a useful and functional part of dental clinics so they are allowed to work in the field. They are similar to the medical assistants who have a certificate in assisting medical doctors.
The medical doctor assistants help the doctors according to the advices and instructions of a doctor. A registered dental assistant can take care of the patients while the dental operators do the treatments. Otherwise, a lot of time would go wasted in dental clinics, as the dentists would have to do everything by themselves. So keeping in view the concept of nurse and medical assistants, the dental assistants were allowed to deliver their services. They act like the extra hands of the dentist and save time of patients as well as of the dentist. The only thing important to become a dental assistant is to get registered with the authorities. Without the registration, no one is allowed by law to practice dental assistance. In some countries, the dental assistants work without a college degree. However, they are required to get a license from the state authorities. The dentists appoint a person only if he has the license with him. The dental hygienists are entirely different from the registered dental assistant as they have college and professional degree in the dentistry.
In some countries, the registration is done instead of licensing. However, the ultimate aim is the same of registration and licensing a dental assistant. However, there are different requirements to become a dental assistant, all over the world. Some countries do not put a check on the dental assistants, especially in the developing countries; people are delivering their dental assistance without any registration. The fear attached to the unregistered dental assistants is the reliability and assurance of professional services. The licenses are issued to a limited number of people only to control the flow of individuals offering there assistance.
Moreover, a registered dental assistant can specialize in different areas of dentistry and can assist the dentist of the similar kind. A cosmetic dentist hires an assistant who has knowledge and specialization in making arrangements and handling the cosmetic dentistry cases. However, the knowledge of processes and procedures is necessary for a person who acts as an assistant to the dentist. For this reason, in United States of America, a professional diploma is offered to the people who want to become registered assistants. Therefore, the assistants first learn and see the dental processes and treatments before they start to assist.
