Recommended Method For Sterilization of Carbide Burs

The most common sterilization methods are listed in preferred sequence

1. Dry heat sterilizers -170 degrees C (340 degrees F) for 1 hour.

2. Chemclaves- Unsaturated chemical vapor 132 degrees C (270 degrees F) for 20 minutes @ 20 p.s.i.

* The above two methods used to manufacturer's specification will not corrode or dull carbide burs.

3. Steam autoclave procedure

      3.1 Mechanically remove debris from bur grooves with brush  

      3.2 Place in ultrtasonic cleaning solution recommended for surgical instruments 

      3.3 Disinfect with instrument non-corrosive disinfecting cleaning agents (avoid contact with hydrogen peroxide).

      3.4 Rinse in mild soap and water.

      3.5 Sterilize at 135 degrees C or (270 degrees F)  for 15 minutes @ 15 p.s.i. at highest bar (you may increase any of these parameters, but not decrease them).

      3.6 Follow autoclave drying time instructions

* These systems are an effective sterilization method for carbide burs. However, certain precautions must be maintained to avoid corrosion or break down of the carbide cutting blades.

A. Avoid any metal contact during sterilization or drying stages (you can experience galvanic corrosion).

Special heat resistant plastic bur blocks are recommended.

B. Certain cold sterilizing solutions or chemical substances, such as isopropyl alcohol, can weaken or attack the carbide bonding agent and or joint connection between the stainless steel shank and carbide head.

Instrument should be thoroughly cleaned and rinsed prior to steam autoclaving.

Note: Avoid hydroxides.
