650—20.2(153) Definitions. As used in this chapter:
“Dental assistant” means any person who, under the supervision of a dentist, performs any extraoral services including infection control or the use of hazardous materials or performs any intraoral services on patients. The term “dental assistant” does not include persons otherwise actively licensed in Iowa to practice dental hygiene or nursing who are engaged in the practice of said profession.
“Direct supervision” means that the dentist is present in the treatment facility, but it is not required that the dentist be physically present in the treatment room while the registered dental assistant is performing acts assigned by the dentist.
“General supervision” means that a dentist has examined the patient and has delegated the services to be provided by a registered dental assistant, which are limited to all extraoral duties, dental radiography, intraoral suctioning, and use of a curing light and intraoral camera. The dentist need not be present in the facility while these services are being provided.
“Personal supervision” means the dentist is physically present in the treatment room to oversee and direct all intraoral or chairside services of the dental assistant and a licensee or registrant is physically present to oversee and direct all extraoral services of the dental assistant.
“Public health supervision” means all of the following:
	1.	The dentist authorizes and delegates the services provided by a registered dental assistant to a patient in a public health setting, with the exception that services may be rendered without the patient’s first being examined by a licensed dentist;
	2.	The dentist is not required to provide future dental treatment to patients served under public health supervision;
	3.	The dentist and the registered dental assistant have entered into a written supervision agreement that details the responsibilities of each licensee/registrant, as specified in subrule 20.16(2); and
	4.	The registered dental assistant has an active Iowa registration and a minimum of one year of clinical practice experience.
“Trainee status expiration date” means the date established by the board office which is 12 months from a person’s first date of employment as a dental assistant. The trainee status expiration date is the date by which a trainee must successfully complete requirements and become registered as a dental assistant, pursuant to Iowa Code section 153.39.

	20.5(1) Dental assistant trainee. Dental assistant trainees are all individuals who are engaging in on-the-job training to meet the requirements for registration and who are learning the necessary skills under the personal supervision of a licensed dentist. Trainees may also engage in on-the-job training in dental radiography pursuant to 650—22.3(136C,153).
	a. 	General requirements. The dental assistant trainee shall meet the following requirements:
	(1)	Prior to the trainee status expiration date, the dental assistant trainee shall successfully complete a course of study and examination in the areas of infection control, hazardous materials, and jurisprudence. The course of study shall be prior approved by the board and sponsored by a board-approved postsecondary school.

	(3)	If a trainee fails to become registered by the trainee status expiration date, the trainee must stop work as a dental assistant.
	b. 	New trainee application required if trainee not registered prior to trainee status expiration date. Pursuant to Iowa Code section 153.39, a person employed as a dental assistant has a 12-month period following the person’s first date of employment to become registered. If not registered by the trainee status expiration date, the trainee must stop work as a dental assistant and reapply for trainee status.
	(1)	Reapplying for trainee status. A trainee may “start over” as a dental assistant trainee provided the trainee submits an application in compliance with subrule 20.7(1).
	(2)	Examination scores valid for three years. A “repeat” trainee is not required to retake an examination (jurisprudence, infection control/hazardous materials, radiography) if the trainee has successfully passed the examination within three years of the date of application. If a trainee has failed two or more examinations, the trainee must satisfy the remedial education requirements in subrule 20.11(1). The trainee status application will not be approved until the trainee successfully completes any required remedial education.
	(3)	New trainee status expiration date issued. If the repeat trainee application is approved, the board office will establish a new trainee status expiration date by which registration must be completed.
	(4)	Maximum of two “start over” periods allowed. In addition to the initial 12-month trainee status period, a dental assistant is permitted up to two start over periods as a trainee. If a trainee seeks an additional start over period beyond two, the trainee shall submit a petition for rule waiver under 650—Chapter 7.
	c. 	Trainees enrolled in cooperative education or work study programs. The requirements stated in this subrule apply to all dental assistant trainees, including a person enrolled in a cooperative education or work-study program through an Iowa high school. In addition, a trainee under 18 years of age shall not participate in dental radiography.
	20.5(2) Registered dental assistant. A registered dental assistant may perform under general supervision dental radiography, intraoral suctioning, use of a curing light and intraoral camera, and all extraoral duties that are assigned by the dentist and are consistent with these rules. During intraoral procedures, the registered dental assistant may, under direct supervision, assist the dentist in performing duties assigned by the dentist that are consistent with these rules.
