Dear Patients and Colleagues:


We sincerely hope that your family is healthy and safe as we cope with the COVID-19 outbreak. 

We have finally reopened our doors to take care of your dental needs. During our temporary closure we donated 100's of masks and cases of gloves to our medical peers to bridge them during supply chain backups. During our closure, we have been busy as an office and profession to learn about this virus and develop a plan to implement the safe return to work.

At Johnstone Periodontics, Cleaner Air in the surgical office is our highest priority. Because of this, we have instituted a number of strategies to improve the air quality and reduce the chance of bio-aerosols circulating in our office.  

  1. We have installed “Purevac“ high volume evacuation tips for all surgical and hygiene rooms. This enables a one-handed approach to evacuate the patient's oral cavity of aerosols, splatter, fluid, and debris, while also providing retraction, visibility, and illumination to the treatment area.  This system helps to eliminate over 90% of aerosols created during dental procedures.
  2. We have installed a custom plexiglass shield in our front desk reception area. Our acrylic hygiene sneeze guard allows us to operate safely, not only to protect our frontline administration team but also to protect and reassure our patients keeping adequate physical distance in our reception area.  No metal surfaces are used, meaning a shorter life span for any contaminating virus.
  3. We have implemented the use of pre-treatment peroxyl rinses for all of our patients. This 1.5% hydrogen peroxide rinse is shown to lower the potential viral load in the oral cavity, and thus facilitate the fight against oral transmission.
  4. We have gone completely paperless!! We have acquired advanced digital e-signing pads which will enable us to wipe down and disinfect them after every use.
  5. We have ordered eight additional Surgically Clean Air Purifiers in addition to our large surgically clean air unit we have had for the past 8 years. These medical grade air purification systems utilize a multi-stage air purifying technology, including proprietary HEPA-RX filters and UV lights to work together to clean, purify and re-energize the indoor air. The six stage filtration system works to remove particulate matter from the air – including potentially infective droplet nuclei. This reduction (dilution) or complete elimination of viruses, fungal and bacteria (99.9%) breaks the cycle of airborne disease transmission and reduces patient anxiety. “It’s like hand sanitizer for your indoor air”. This filtration system removes dust and pollen that cause allergies, kills bacteria and viruses that make people sick, eliminates odors and irritating volatile organic chemicals (VOC) and, re-energizes stale indoor air to facilitate breathing. This system leaves everyone feeling more revitalized.

As surgical professionals, we are compelled to make every effort to reduce the possible transmission of disease and route of infection. At Johnstone Periodontics we have taken necessary precautions in protecting our patients and staff from the transfer of infection by reducing the levels of bio-aerosols within our office. We look forward to seeing your smiling faces soon!
