A dentist who is personally present, operating as a dentist or personally overseeing the operations being performed in a dental office, over fifty percent of the time that such office is being operated, shall identify himself/herself in any representation to the public associated with such office or practice and shall provide readily visible signs designating his/her name at such respective office entrances or office buildings. Any representation that omits such a listing of dentists is misleading, deceptive, or improper conduct. Dentists who are present or overseeing operations under this rule less than fifty percent of the time shall identify themselves to patients prior to services being initiated or rendered in any fashion. Every office shall have readily available a list of the names of dentists who are involved in such office less than fifty percent of the time.
