No matter how much we use technology the prime focus of the dentist and assistant must be delivering fine dental treatment. If the technology gets in the way of doing dentistry the technology is in the wrong place.
There is a zone around the head of the chair, the dentistry first area, which should be reserved for dental treatment only, no computers. This is also the zone of potential contamination from aerosol.
It is not possible to sterilize a computer. You can’t dip the mouse in the cold sterile or spray the keyboard. At least you can’t do it more than once. There are ways to cover and decontaminate the computer components but one of the best techniques is to simply keep them out harms way.
