New Jersey's Board of Dentistry rules define three dental assistant categories: a registered dental assistant, a limited registered dental assistant in orthodontics, and an unregistered dental assistant.
Registration is required only for the expanded-functions and orthodontic tiers; an unregistered assistant may still perform a defined list of duties, including radiographic exposures, under a dentist's direct supervision.
Direct supervision is the only supervision term the subchapter defines, meaning the dentist is physically present in the office at all times.
Registered dental assistants complete 10 hours of continuing education every two years.

The subchapter sets out three scopes of practice: a registered dental assistant (13:30-2.4), a limited registered dental assistant in orthodontics who works under a Board-permitted orthodontic specialist (13:30-2.5), and an unregistered dental assistant who has not obtained a Board registration (13:30-2.6).
Each section lists its own set of duties a dentist may delegate under direct supervision.
A dental assistant who has not obtained a registration from the Board may perform the following duties under the direct supervision of a licensed dentist:
The current registration pathway requires the applicant to have passed the Certified Dental Assistant Examination administered by DANB within 10 years, complete the online New Jersey Jurisprudence orientation within six months of applying, and either graduate from a Board- and CODA-approved dental assisting program, or complete high school plus two years of work experience and then pass the New Jersey Expanded Functions Examination or a Board-approved expanded-functions program.
The application must also include a certification of good standing from every other state where the applicant is registered, a criminal history background check, and the fee set at N.J.A.C. 13:30-8.1.
An applicant seeking registration as a dental assistant shall have passed the Certified Dental Assistant Examination administered by the Dental Assisting National Board (DANB) within 10 years prior to the date of application, have a certificate of completion of the online New Jersey Jurisprudence orientation taken within six months of the date of application, and shall have:
Direct supervision is the only supervision term this subchapter defines, and it governs every duty list in Subchapter 2.
It requires the licensed dentist to be physically present in the office at all times the assistant performs the act, under the dentist's order, control and full professional responsibility.
The subchapter names no separate general-supervision or off-site supervision tier for dental assistants.
"Direct supervision" means that a licensed dentist is physically present in the office at all times during the performance of any act and that such acts are performed pursuant to the licensed dentist's order, control and full professional responsibility.
Under a licensed dentist's direct supervision, a registered dental assistant may perform a long list of delegated duties: isolating the operative field including rubber dams, placing and removing matrices, temporary restorations, and periodontal dressings, fabricating and cementing temporary crowns and bridges after the dentist preps the tooth, taking alginate and orthodontic impressions, applying topical anesthetic and fluoride, trial-sizing and placing orthodontic bands and arch wires, taking vital signs and dental photographs, and making radiographic exposures.
A dental assistant of any tier may also issue a written work authorization for emergency repair of a prosthesis that requires no intra-oral procedure and is later inserted by a licensed dentist.
A registered dental assistant may perform the following duties under the direct supervision of a licensed dentist:
All three tiers may make radiographic exposures, each listed as its own delegable duty as permitted by the Department of Environmental Protection under N.J.S.A. 26:2D-24 et seq.
The subchapter cites that state radiation-control statute rather than a Board of Dentistry radiography permit, course or exam, and applies the same wording to the registered, orthodontic-limited, and unregistered tiers alike.
Make radiographic exposures as permitted by the Department of Environmental Protection pursuant to N.J.S.A. 26:2D-24 et seq.
A dental assistant of any tier may assist a licensed dentist in administering nitrous oxide, provided the dentist stays physically present in the operatory throughout.
A registered dental assistant may go further and monitor a patient the dentist has already sedated with nitrous oxide/oxygen, performing no other function while monitoring, but only after completing a Board-approved course of at least 14 hours (at least seven hours didactic and seven hours clinical, including 10 monitored administrations) in a CODA-approved setting, holding current Basic or Advanced Cardiac Life Support certification, and completing a three-hour recertification course every other renewal period in addition to regular continuing education.
Monitoring without meeting these standards, or without direct supervision, is treated as a deviation from normal practice standards and unauthorized practice.
A registered dental assistant practicing under the direct supervision of a licensed dentist pursuant to N.J.A.C. 13:30-8.20 may monitor a patient to whom the supervising dentist has administered nitrous oxide/oxygen inhalation analgesia provided the registered dental assistant does not perform any other function while monitoring the patient, and provided that:
Registered dental assistants and limited registered dental assistants in orthodontics must certify 10 hours of continuing education every two years at renewal, including six mandatory hours: three hours of hands-on CPR/AED certification, one hour of infection control, one hour of professional ethics and New Jersey law, and one hour on prescription opioid drugs.
No more than half of the 10 hours may come from distance learning, and the Board will waive up to two of the non-mandatory hours for documented volunteer clinician service.
All registered dental assistants and limited registered dental assistants in orthodontics shall submit a certification verifying the completion of 10 hours of continuing education every two years at the time of registration renewal, including the six mandatory continuing education hours set forth at (f) below.
Only for two of the three tiers.
N.J.A.C. 13:30-2.2 requires registration to work as a registered dental assistant or a limited registered dental assistant in orthodontics, each with its own exam and application requirements.
The source also defines an unregistered dental assistant category that may perform a shorter list of duties, including radiographic exposures, under a dentist's direct supervision without Board registration.
Confirm current forms and fees with the New Jersey State Board of Dentistry.
Yes, at every tier.
N.J.A.C. 13:30-2.4, 13:30-2.5 and 13:30-2.6 each list making radiographic exposures as a duty a registered, orthodontic-limited, or unregistered dental assistant may perform, as permitted by the Department of Environmental Protection under N.J.S.A. 26:2D-24 et seq.
The subchapter names no separate Board of Dentistry radiography permit, course or exam.

New Jersey's rules use only one supervision standard for dental assistants: direct supervision.
N.J.A.C. 13:30-2.1 defines it as the licensed dentist being physically present in the office at all times an act is performed, under the dentist's order, control and full professional responsibility.
The subchapter defines no lesser, off-site supervision tier for any assistant category.
Check with the New Jersey State Board of Dentistry before relying on this for a specific task.
A registered dental assistant may monitor a patient already sedated with nitrous oxide/oxygen, but only after completing a Board-approved course of at least 14 hours (seven didactic, seven clinical, including 10 monitored administrations) at a CODA-approved setting, per N.J.A.C. 13:30-2.4.
The assistant must also hold current CPR/ACLS certification and complete a three-hour recertification course every other renewal period.
Monitoring without meeting these standards is treated as a deviation from normal practice.
Confirm current course approval with the Board.
N.J.A.C. 13:30-5.3 requires 10 hours of continuing education every two years, including six mandatory hours: three hours of hands-on CPR/AED, one hour of infection control, one hour of ethics and New Jersey law, and one hour on prescription opioids.
No more than half of the 10 hours may come from distance learning.
Up to two of the non-mandatory hours may be waived for documented volunteer clinician service.
