The practice of dental hygiene may be conducted in the office of any licensed dentist or in any appropriately equipped school or public institution but must be done either under the supervision of a licensed dentist 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 and registered dentist who has a formal relationship with the same hospital in accordance with regulations promulgated by the department in consultation with the department of health.
