I believe developing a relationship with the patient is crucial.  Patients can tell when you are in a hurry.  I do all the initial exams and prophies in my office.   It gives me a chance to talk to the patient throughout the entire length of the relatively low key first visit and allows for the bonding that needs to occur for the patient to trust you.  Without trust, no matter how many gimmicks you have in the office, the patient will always remain nervous.
