Patient safety is always a priority of any dentist. Dental practices are changing the way they operate to avoid cross-contamination. The main dental procedure which causes this kind of contamination is aerosol production. There is no such thing as a miracle handpiece that generates zero aerosols. However, there are many options in terms of choosing the best handpiece which meets all your needs and at the same time produces less aerosol. In these handpieces, the Anti-Retraction Valve (ARV) plays a very important role in dental use.
The risk involved if ARV technology is not used
A Handpiece without an anti-retraction valve may aspirate and expel the debris along with fluids during the dental procedure. The microbes, including bacteria and viruses, may further contaminate air and water hoses within the dental unit. This can potentially be a source of cross-infection. As the hose, water block, and valves are not sterilized, contamination presents a huge problem. Not all handpieces incorporate this technology. In fact, if you count in all non-branded local handpieces, they don’t have an anti-retraction valve feature.
Importance of ARV technology in Dentistry
A dental handpiece without an anti-retraction valve in the air rotor causes all the contaminated aerosols to stay in the hoses and when next time you are doing a patient, contamination will occur harming both patients as well as the dentist hence its very essential to have this safety feature in your handpiece.
What is Anti retraction dental Handpiece?
Good companies being conscious of cross-contamination, have designed high-speed handpieces with anti-retraction valves which protect fluid retraction from the oral cavity into non-sterilized dental handpiece tubing and water lines.
One such handpiece by NSK is a New FX Plus high-speed handpiece with the power of 30W and anti-retraction valve technology. The redesigned FX plus turbine cartridge provides smoother performance. The body of stainless steel is secure in the hand and angled to an optimum degree for excellent direct visibility of the operating site without any compromise.
Interesting features of NSK FX handpiece
The new ARV technology helps prevent the backflow of debris into the handpiece through water, thus preventing debris from getting clogged and avoiding its harmful effect by preventing contamination.
Air pressure regulating valve
It ensures a stable pressure supply to the head section of the handpiece avoiding any unnecessary rotational pressure and in short increasing the life of the cartridge.
Clean Head system
This is a unique mechanism that prevents the entry of blood and foreign matter from the oral cavity into the head through the air and helps in reducing contamination as well as enhancing the life span of the bearing.
Additional features of this handpiece are:
·        It has a 25% harder ceramic bearing which greatly reduces friction wear and enhances durability
·        It’s scratch resistant, giving a comfortable grip
·        There is Quattro spray which avoids Tissue necrosis
Conclusion:
Investing in a high-quality, high-performance handpiece generally ensures you are getting features like anti retraction valve. Along with it, treatments can be carried out smoothly and at a faster rate-limiting dentists’ exposure to aerosols. The New FX plus high-speed handpiece has been enhanced in modern dental practices to meet the standards
