In It Together

A community sourced archive,
documenting COVID-19’s impact
on dentistry

Many in the dental community have been affected by COVID-19 and want to share their stories.

As a result, the ADA is launching the JADA+ COVID-19 Monograph—a digital collection of stories, reflections, and accounts from any perspective, in any format, including articles, essays, podcasts, videos, graphics, and photos—that is open to all contributors. Submit your COVID-19 story here.

Ionization: A Possible Answer to the Reduction of Transmission of Viruses in Interior Spaces – Dr. Murray Rosenthal


I have done some research as to sterilizing interior areas and have come across the benefits of
needlepoint bipolar ionization (NPBI). I contacted an owner of Aviation Clean Air regarding the benefits of this. The following is the letter he sent me and two attachments.  My feeling is that if one places UV units in ventilation ducts, increases air ventilation rates per hour, and utilizies NPBI, then one can have an almost sterile environment for dental offices and schools. I have a freestanding bipolar ionization unit in my office.

Letter from Aviation Clean Air:

Thank you again for your interest in ACA and our Needle Point Bi Polar Ionization (NPBI™).

As we discussed, our company specializes in the aerospace industry but we have developed a portable Ion Distribution Unit that can be used in any occupied space (such as a theater) with the same result in neutralizing all pathogens (including Covid 19 as proven in the attached laboratory results), eliminating all mold spores, removing airborne particulate, and neutralizing contaminants.

Our NPBI™ technology is currently being used around the world in aircraft and facilities as the primary control of providing safe and clean air and surfaces.
