Assigned to HHS FOR COMMITTEE
ARIZONA STATE SENATE
Fifty-Seventh Legislature, First Regular Session
FACT SHEET FOR S.B. 1124
dental board; oral preventive assistants
Purpose
Establishes a pathway for dental assistants to practice as oral preventative assistants (OPA)
upon completion of an expanded functions training course approved by the Arizona State Board
of Dental Examiners (BODEX).
Background
Current statute allows dental assistants to expose radiographs for dental diagnostic
purposes, under the general supervision of a dentist or the direct supervision of a dental hygienist,
if the dental assistant has passed a BODEX-approved examination. Similarly, dental assistants
may polish the natural and restored surfaces of teeth under the general supervision of a dentist or
the direct supervision of a dental hygienist, if the dental assistant has passed a BODEX-approved
examination (A.R.S. § 32-1291).
A dental assistant is any person who acts as an assistant to a dentist, dental therapist or
dental hygienist by rendering personal services to a patient that involve close proximity to the
patient while the patient is under treatment or observation or undergoing diagnostic procedures
(A.R.S. § 32-1201).
An OPA is a type of expanded function dental assistant who has taken the required
education and completed training to provide patients with additional preventive services and assist
hygienists with preventive care practices. OPAs remove hard build up on visible, healthy teeth or
on patients with reversible gum inflammation (American Dental Association).
There is no anticipated fiscal impact to the state General Fund associated with this
legislation.
Provisions
1. Requires a dental assistant seeking to practice as an OPA to complete a BODEX-approved
OPA expanded functions training course.
2. Requires a dental assistant, prior to enrolling in an OPA expanded functions training course,
to:
a) complete a BODEX-approved course containing didactic and hand skills assessment; and
b) be certified as a dental assistant by a BODEX-approved certification program.
3. Limits the practice of an OPA, in the first five years of licensure, to only federally designated
health provider shortage areas or counties with fewer than 250,000 people. FACT SHEET
