SB 1124 Arizona Senate · 57th Legislature - First Regular Session

dental board; oral preventive assistants

SB 1124 creates a new role for "oral preventive assistants" in Arizona dental practices. To qualify, dental assistants must complete a 120-hour board-approved training course (including CPR and specific certifications) and work only under dentist or hygienist supervision (dentists may supervise up to three assistants). These assistants can only remove plaque and tartar on periodontally healthy patients or those with mild gingivitis, using specific tools and avoiding air polishing or medically complex cases. The bill requires dental boards to collect data on these assistants until 2028, after which the law expires. It directly affects dental assistants seeking this role, supervising dentists/hygienists, and patients receiving preventive dental services.
