Course Description

Radiation Safety for the Dental Auxiliary
*As defined by the Kentucky Board of Dentistry

Course Approval #KBD0032


The Kentucky Board of Dentistry amended the minimal educational requirements for dental auxiliary personnel prior to taking dental radiographs under a dentist's direct supervision (201 KAR 8:57OE). All dental auxiliary personnel must satisfy the following two (2) requirements before taking x-rays in a dental office:

1. Didactic: Completion of a course in Radiation Safety: This can be verified by providing proof of completion of the Radiography Section of the Dental Assistants National Board Examination or attending an approved continuing education (CE) course (6 hours minimum) provided by a certified presenter.

2. Practical: A practicum course in x-ray technique (4 hours minimum). This is verified by a dentist's written documentation of a student's completion of four hours of instruction in dental radiography technique in the practice or by attending a four hour continuing education course in radiography technique approved by the Board before being allowed to expose radiographs. A copy of the Technique Training Form must be returned within a maximum of sixty (60) days from the date of course completion to the Office of Continuing Education. Once received, a Certificate of Completion will be issued. Non-compliance will result in an automatic failure. Failure to pass course will result in one (1) opportunity to re-take the entire course at 50% reduction of current course fee within one (1) year.

This Course satisfies the Didactic requirements of the Kentucky Board of Dentistry. After the course is presented, an examination will be given. Successful completion of the course requires a 75% pass in a multiple-choice question examination administered at the end of the course. Participants who successfully complete the examination MUST then fulfill requirement #2 above prior to exposing radiographs on patients under the direct supervision of a dentist.
