Aerosols: Science Using Common sense...

There Are several dental suction mirror devices on the market claiming to be HVE but are really simply just plug into the HVE and really don't perform at the level necessary and in some cases are at the level of a saliva ejector or less. Simply having a large bore device used in an office having a weak suction system could be a recipe for disaster and backwash. Port velocity the right ratio to volume is key to multi factor issues encountered in dental offices. To answer your questions requires in-depth understanding of how this all works in regards to all the variables and if they can be controlled ie variable vs invariables in the testing process.  I understand what CDC mentions in the webinar. In reality, this would suggest all dental offices use the exact same vacuum system, layout, line size, number of op's and the exact same number of clinicians using the exact same devices at the same time. I believe my point is understood. Device design is extremely important and how clinically it is used. Simple designed devices often become complicated to use. NuBird dental evacuation mirror is designed to meet the needs of the clinicians by allowing focus on primary tasks while the mirror design will handle the aerosols provided the clinicians are using the device, office vacuum system is in working order (9-14 mmhm static pressure reading at the HVE valve end and the traps and lines are not clogged up with Fl varnish. 250 NL/min. (may be from CDC?) is referring to the dental office vacuum motor itself as devices themselves cannot "self" create vacuum and are connected to a vacuum motor to work. Being 98% in aerosol reduction starts first at the vacuum motor then the supply lines and ends at the terminus end point (device being used) Let's be realistic...My point, an unpowered device plugged into a dental office vacuum system cannot achieve more than what that system is performing at. Terminus end point is where the patented NuBird evacuation Mirror system performs above all others from start to finish.  Simple tests can be performed by anyone to actually see the difference in device design as I have demonstrated and have suggested in articles published in magazines. I encourage and strongly suggest these tests be performed by the users of HVE devices. There are so many variables to address I could write a book about this and may in the future. Read the article on our Blog called Technology, Dentistry and HV Evolution. This will help explain more in detail the science and give more understanding.  Be informed and STAY SAFE.

NU-bird’s New HVE Valve unit adapts directly to our Ergonomic HVE hose, allows clinicians to easily switch from Hygiene to restorative procedures which require a standard HVE tip in a snap.One of a kind, we are first to introduce a small compact ergonomic HVE VALVE. LIGHTER IN WEIGHT and more ergonomic to use then standard HVE valve units. Standard clinical aluminum HVE valves, WEIGH approx. 2oz and stainless steel versions weigh up to 4 oz. !! this is not including the weight of the standard HVE hose attached which can weigh up to 1lb! The Nu-Bird HVE Valve only weighs 1/2 oz!! Our HVE hose weighs approx. 4 oz. These are extremely important features and make it easy for clinicians to use who normally avoid using standard HVE because of the weight on the wrist and hand and repetitive strain it can cause.

The NuBird SR Banchi Series! On this new model, the HVE valve is integrated directly into the handle of a suction mirror for easy ON/OFF control of suction. Your efficiency improves because with it, you don’t have to reach over to the delivery system to turn the suction on or off thus making it more ergonomic to use. It's a must for clinicians who work without an assistant performing both restorative and hygiene procedures.

An in-depth look at answering the question: "How do I know if my HVE device is able to remove 98% of the aerosols I generate?"

Multi directional ports have continuous air flow even when the mirror is pressed against mucosal tissue so the mirror won't fog and you will have plenty of power to remove water and aerosols (KEY) before they leave the mouth!

High volume, high port velocity and a wide air pathway in dental evacuation is needed for proper management of water and aerosols.

It’s What You Can’t See That Can Hurt You Recently, when a hygienist contracted a virus at work, it came on so quickly and aggressively that she ended up taking a whole month off at home to recover. Eventually, all of the other staff...
