The Handpiece Post
Did you know the most common concern about dental instruments that are stained is that they may be rusting. In fact rusting on quality instruments is very unusual and the discoloring may indicate improper care. The discoloration is usually due to improper cleaning and is indicative of some type of deposit left on the instrument.
The stain will typically show up after sterilization.
Notice the color of the stain, this will help in the identification of the source of the stain.
If you have a stain that is light brown, dark brown and or slight orange in color, look for dried blood being the most common.
Other causes are cold sterilization, some detergents, instrument wrappings and or your water supply. This color of stain represents a phosphate layer has formed on the instrument causing the discoloration.
When you have a black stain, the most common cause is the detergent used for cleaning.
Check that the PH in your cleaning solution is optimal for the instrument. A PH that is too high or too low can cause an acidic reaction. Check with your distributor or manufacturer for the recommended solution.
The most common stain is dried blood left on the instrument causing a dark brown color. Dried blood will react to the instrument causing a corrosive reaction. All blood should be cleaned immediately and thoroughly.
