Rheostat leaving the ground is insanity.

Do not let any thing touch your dental gown. The dental gown has aerosol spray on it from when a dental assistant has been nursing, using suction in the patient's mouth, so the gown is contaminated once dental assistant has nursed. Take polyvinyl container over to dental cart/tray, and place end of polyvinyl=the end furthest away from cutting edge and let this end adhere[stick] to one side of the tray, hold pre-cut end on one side of tray, & let other end unravel until whole of tray is covered, then cut as required

Very informative,

Good dental assistant

how " if the chair needs to be clean?" They need to be clean after every patinet! Using your empty hands to put on those plastic protection on the chair, is bad, why not use protective gloves? All those plastic barriers are waster by placing them with empty hand, it doesn't matter how much you was your hand before! Sorry, but is wrong! It took a lot of time to prepare, how can someone prepare like this when u have a patient one after another after every hr ?
