The DryShield unit has been amazing. I have used other more and less expensive brands of these types of suction units, and I can say without a doubt that this one performs the best in my opinion. It is simple to use and install, taking less than a minute of my assistant’s time when installing the traveling unit; and even less with a dedicated high evacuation line. My patients have nothing but good things to say about it, and I have had multiple patients fall asleep while using the unit. I use this for nearly every restorative procedure you could think of. The unit is excellent for everything from quadrant dentistry to full mouth rehabilitation cases. The use of DryShield has allowed me to cut my restorative times nearly in half. You can avoid constant swallowing breaks or the inevitable grasping of mucosa with high evacuation suction simply by placing this mouthpiece. This has also allowed my assistant’s the freedom of running into and out of the room (such as the case when performing same day crown preparations and seats) without leaving me feeling stranded or frustrated. Anyone who has ever used a bite block is an excellent candidate for this system’s use from pediatric to geriatric care. When cleaning the system, it has been very simple and time effective by simply following the manufacturer’s recommendations (which you will likely give directly to your assistants). This is one of the best purchases I have made in my short career as a dentist and foresee buying additional units for all of my restorative rooms.
