After removing the handpiece from the autoclave bag, but before gloving, install a bur in the chuck and run the attachment without the water spray for approximately 15 seconds. After the Dental Burs stops turning, gently grasp the head of the attachment with an ungloved thumb and forefinger to feel for any heat. A properly functioning electric 1:5 speed increasing attachment may feel warm to the touch after this but it should NOT feel HOT. If you have any doubts, repeat this procedure for a longer period of time to see if the head does get progressivley hotter? If you still have any doubt about the amount of heat generated from the head send the unit out for evaluation.
I am amazed at how quickly these heads get painfully hot. Today I am working on an attachment that took a little longer than 15 seconds to heat up. When I got the dental Handpiece Cartridge apart, the bearings were intact, but there was a tiny crack in the bearing retainer! The slightest defect can lead to serious heat fast!
A Dental Bur is a piece of equipment used by dentists to drill holes in the teeth of their patients. The dental bur is only part of a larger set up - the dental drill. Basically, the bur is the drill bit that does the actually cutting or drilling action.
There are many kinds of Dental Burs, and they are actually quite specialized. A dentist will have a whole set of dental burs, each piece having a specific function. While each type of dental bur may have unique properties, they all have the same basic parts. There is the head, the neck, and the shank. It is the shank that is used to connect to the dental drill, while the head is the "blade" which cuts into the teeth.
Dentists have the option of purchasing disposable and reusable Dental Burs. The former is cheaper and has to be thrown away after each use. The advantage of doing this is that the dentist does not have to bother with sterilization. the time required for cleaning and sterilization is saved. The team required to clean and scrub these prior to sterilization is no longer required and reduces the costs involved. Moreover, having new dental diamond burs to use each time ensures unparalleled sharpness. If the item is not used more than once, there is no risk of infection spreading from one patient to another.
Reusable dental burs may be better in the long run, though, as they can be used over a long period of time. Reprocessing may well not free these from bioburden and also this may raise the risks regarding infection to other individuals. Another risk could be the worker reprocessing or perhaps cleaning gets infected at the same time. In several instances, these kinds of accidental post-exposures have never been reported.
