(1)  When a patient has a strong gag reflex, it is best to expose the most difficult images first and then move on to those that are easier to tolerate to finish on a positive note.  (2)  Using a single decisive motion that brings the receptor firmly into contact with the palate is recommended to prevent the gag reflex.
