 FAQ  - Instrument Processing - 2015

 

 


I have heard that carbide/diamond burs should be presterile single use devices. Can you tell me where I can go to access information on this or send me a link?

In the CDC guidelines for Dentistry 2003 this is all that I could find.  

“Because of the physical construction of certain devices (e.g., burs, endodontic files, and broaches) cleaning can be difficult. In addition, deterioration can occur on the cutting surfaces of some carbide/diamond burs and endodontic files during processing (384) and after repeated processing cycles, leading to potential breakage during patient treatment (385--388). These factors, coupled with the knowledge that burs and endodontic instruments exhibit signs of wear during normal use, might make it practical to consider them as single-use devices.”

Ask OSAP was also present at last year’s Symposium. It was also stated at that time that this fell under the jurisdiction of the US Food and Drug Administration (FDA) and that further information and clarification would have to come from that agency.

You are correct that the 2003 CDC guidelines for infection control in dentistry states as follows:

Because of the physical construction of certain devices (e.g., burs, endodontic files, and broaches) cleaning can be difficult. In addition, deterioration can occur on the cutting surfaces of

some carbide/diamond burs and endodontic files during processing (384) and after repeated processing cycles, leading to potential breakage during patient treatment (385–388). These factors, coupled with the knowledge that burs and endodontic instruments exhibit signs of wear during normal use, might make it practical to consider them as single-use devices.1

Additionally, OSAP states in its FAQ’s:

Like other contaminated disposable sharps, used burs should be discarded into sharps containers (1). Because dental burs are difficult to clean and are degraded by the sterilization process, dental offices should consider making burs a single use disposable item. 2

Further questions about burs (i.e., feasibility of sterilization and recommendations for processing, instructions for use---IFU) should be directed to the manufacturer of the specific bur.
