for the Dentalys clinic or work Mr. Stephani....on their website they note that they have assistants in prophylaxis which is wrong for some of them! Because they did not make the patent and therefore have no paper and should not work in the mouth! I am assorted for prophylaxis myself I know what I am talking about. It's cheating on the patient! What else is wrong with this clinic? So mistrust of this kind of practice which is charged of course! It is you, the patient, who suffers. Fortunately there are other more correct dentists elsewhere.
