2021 New York Laws EDN - Education Title 8 - The Professions Article 133 - Dentistry, Dental Hygiene, and Registered Dental Assisting 6608 - Definition of Practice of Registered Dental Assisting.

§ 6608. Definition  of  practice  of  registered dental assisting. The   practice  of  registered  dental  assisting  is  defined  as   providing   supportive  services  to  a  dentist in his or her performance of dental   services authorized under  this  article.  Such  support  shall  include   providing  patient  education,  taking preliminary medical histories and   vital signs to be reviewed by the dentist, placing and  removing  rubber   dams,   selecting  and  prefitting  provisional  crowns,  selecting  and   prefitting  orthodontic  bands,  removing  orthodontic  arch  wires  and   ligature ties, placing and removing matrix bands, taking impressions for   study  casts  or  diagnostic  casts, removing periodontal dressings, and   such  other  dental  supportive  services  authorized  by  the   dentist   consistent  with  regulations  promulgated by the commissioner, provided   that such functions are performed under the direct personal  supervision   of  a  licensed  dentist  in  the  course  of  the performance of dental   services. Such services shall not include diagnosing  and/or  performing   surgical  procedures,  irreversible  procedures or procedures that would   alter the hard or soft tissue of the oral and maxillofacial area or  any   other   procedures   determined  by  the  department.  The  practice  of   registered dental assisting may  be  conducted  in  the  office  of  any   licensed  dentist  or  in  any  appropriately  equipped school or public   institution but must be done under the direct personal supervision of  a   licensed  dentist.  Direct  personal  supervision,  for purposes of this   section, means supervision of dental procedures  based  on  instructions   given  by a licensed dentist in the course of a procedure who remains in   the dental office where the supportive  services  are  being  performed,   personally  diagnoses the condition to be treated, personally authorizes   the procedures, and before dismissal of the  patient,  who  remains  the   responsibility of the licensed dentist, evaluates the services performed   by   the  registered  dental  assistant.  Nothing  herein  authorizes  a   registered dental assistant to perform any of the services or  functions   defined as part of the practice of dental hygiene in accordance with the   provisions  of  subdivision one of section sixty-six hundred six of this   article, except those functions authorized pursuant to this section. All   dental supportive services provided in this section may be performed  by   currently   registered   dental  hygienists  either  under  a  dentist's   supervision, as defined in regulations of the commissioner, or,  in  the   case  of a registered dental hygienist working for a hospital as defined   in article  twenty-eight  of  the  public  health  law,  pursuant  to  a   collaborative  arrangement  with  a  licensed dentist in accordance with   subdivision one of section sixty-six hundred six of this  article.  Such   collaborative  arrangement  shall  not  obviate  or supersede any law or   regulation which requires identified services to be performed under  the   personal supervision of a dentist.
