     First, choose the handpieces must carefully examine the following basic principles:


Safety performance



The use of cost


First, the safety performance: critical,dental burs it is necessary to ensure patient safety, the second is to take into account its own security staff. Small two summed up what to pay attention to the following points:


(A) affect the performance of several cross-infection control


1 mobile handpieces selection and exterior coating, whether it can withstand temperatures above 135 degrees autoclaving. Metal or plating process inferior bad handpieces, after repeated autoclaving may damage the rear surface, use will affect the feel, not beautiful.


(2) whether there is anti-suction handpiece design:


Anti-suction design is actually sophisticated one-way valve, which functions as the heart or blood vessels inside the valve, only allows water to drain,dental instruments which can not be sucked back. This would effectively avoid cross-infection from attracting back. See the following references:


Prevention of microbial contamination of the dental unit caused by suction into the turbine drive air lines. Oral Surg Oral Med Oral Pathol Oral Radiol Endod. 1996 Jan; 81 (1) :50-2


The drive air lines of the turbine in the dental unit may become contaminated despite the sterilization of handpieces. The antisuction device installed into the dental unit was found to prevent the contamination.


    Even on the handpieces to a strict sterilization treatment, dental treatment units of the pipeline remains the risk of contamination! Anti-suction device can effectively prevent such pollution!


3, is it possible to receive professional thermal cleaning


Developed countries in Europe, has already been included in the thermal cleaning disinfection of dental instruments, cleaning standards. Significantly reduces the thermal cleaning in direct contact with contaminated handpiecess opportunities, and ultimately will become the mainstream. Therefore, a good cell handpieces must be resistant to heat hot water high pressure cleaning machine washing.



4 Is there a built-in filter


Advanced mobile bearing very sophisticated, so have higher demands on water quality will be in the handpieces into the tube designed to replace the built-in filters to purify water.


(Two), affect the treatment safety critical performance: mobile cooling device.


Each handpieces must spray, but if there is not necessarily a cool place. If the cooling is not good because of thermal damage caused by the pulp, causing prepared teeth after endodontic lesions in trouble. Moreover, this complication occurs, but also often find the reason. Because the operation is no problem ah!! Purchase observe:


Mobile is a few holes spray?Teeth Whitening Machine Four-hole course is the best spray, multi-point cooling, even a hole out of the question, the other holes are also to ensure cooling effect. But porous spray handpieces than single spray to be more expensive.



Spray-point position of the head in the handpieces? The position of the spray reaches bur? The direction of the spray is very important, a good handpieces asks spray stable and accurate, so as to ensure that water mist gathered at the cutting point, to achieve the cooling effect.
