Is there any written publication on ultrasonic vs hand washing instruments before autoclaving?
There have been many articles written on this issue. An article in the American Journal of Dentistry, 8:152-156, 1995, by Cafruny, Brunick, Nelson and Nelson reported that hand scrubbing before sterilization was relatively ineffective. The authors found that there was a greater than 100-fold decrease in blood contamination using an ultrasonic pre-cleaning versus hand scrubbing before sterilization.
