COVID-19 and Dental Practices: Reducing Fallow Time Between Patients
Dentistry in the United Kingdom is classified as being a high risk for transmission of COVID-19. With an estimated 36.4 million dental patients in the UK treated every year, it is vital that you are able to protect your staff and patients. Get the most out of your dental practice with the world-class solutions and services from Total Clean Air; guaranteed to help you thrive in a post-coronavirus lockdown environment.
What Is Fallow Time in Dentistry & How Does COVID-19 Affect It?
The Faculty of General Dental Practice UK and the College of General Dentistry have adopted the shorter fallow times for dental procedures that were recommended by the Scottish Dental Clinical Effectiveness Programme.
New guidance from the UK’s Chief dental officers have reduced the baseline fallow time of 30 minutes where there are one to five air changes per hour (ACH) or the number is unknown.
Where there are six to nine ACH, it recommends a baseline fallow time of 20 minutes. Where there are 10 or more ACH, a baseline fallow time of 15 minutes is recommended. A high fallow time has a severe financial effect on dental clinics, as it greatly limits the number of patient’s dentists can attend to.
COVID-19 Guidance and Standard Operating Procedure for Dentists
The following guidelines will help your practice reflect up-to-date recommendations aimed at preventing coronavirus and other infections and improving care.
1. Remote risk assessment and triage first
Identify high-risk patients before they get to the dental office.
2. Get patient to complete a questionnaire of COVID-19 history
To complete a dental visit, a patient will need to complete the COVID-19 questionnaire.
3. Arrange appointments
Plan appointments for patients, including setting up rooms in advance. Arrange follow-up appointments for patients who are not able to attend their scheduled appointment.
4. Require patients to wash/disinfect their hands-on arrival
Patients must be asked to wash their hands with soap and warm running water immediately on arrival, and this must be meticulously supervised. Any cuts on the hands should be covered by disposable gloves.
5. Have patients’ temperature taken
It is advisable to have patients’ temperature taken and recorded before placing a needle or tray in the mouth.
6. Mandate staff to wear PPE
PPE includes full face masks, disposable surgical helmets, eye protection equipment and mouthpiece for dental staff.
7. Adjust waiting rooms to adhere to social distancing policy
The goal is to make the waiting room areas as free from potential infection as possible by eliminating or reducing contacts with patients, staff or other people not directly involved with treatment.
Instruct your staff to not stand directly next to patients or clients when speaking to them. Remove furniture from large waiting areas and provide clear pathways for movement between patients.
8. Alter appointment timings to allow for social distancing and treatment room preparation
During this outbreak, schedule your appointments to allow a few people in at a time.
9. Disinfect/purify treatment rooms after every appointment
Dental Practices are required to carry out cleaning and disinfection of every treatment room after every patient session. An antibacterial surface cleanser, used as directed in conjunction with a mechanical device for effective cleaning is a suitable solution for the decontamination of non-critical equipment (e.g., stools, chairs, tables) and the floor in treatment rooms.
10. Request patients to wash/sanitise their hands before leaving the clinic
Establish an exit hand hygiene procedure and display reminders on the clinic walls. Provide hand sanitiser. Educate your patients that they should wash their hands with soap or antiseptic and water immediately after leaving the dental clinic.
11. Accompanying persons should not be allowed to enter the clinic unless absolutely necessary
Make sure your patient is the only person who enters your clinic. Allowing entourage to enter will prevent other patients from entering the clinic space and increase the risk of spreading infections. If accompanying persons enter the clinic, they must adhere to the above guidelines
12. Make special arrangements for high-risk patients
Have special arrangements to ensure that (older people or those with underlying health conditions) can be examined safely. Such patients may, for example, need (elderly-friendly care), special patient information or specially trained dental assistants.

Can Fallow Time Be Scrapped with Ventilation and Air Filtration Systems?
What if there was a way to dramatically reduce the risk of infections in dental clinics and consequently scrap fallow time? Current guidance stipulates 30 minutes wait time that starts counting immediately after a high-risk aerosol-generating procedure (AGP). However, this applies only to rooms with one to five air changes per hour (ACH) or the number is unknown. Dental clinics can reduce fallow time by conducting a risk assessment, measuring air change rates, and installing air filtration systems.
Measuring Air Change Rates
Air change rate is the hourly rate at which fresh air can enter or leave a room.
It is a measure used in ventilation design to ensure that indoor air quality is maintained and health impacts from pollutants are minimised. Air volume is an important metric to know when auditing a room’s ventilation, but calculating it is no simple task for dental practitioners. The formula for calculating ACH (air changes per hour) is:
- ACH = CFM x 60 / (Area x Height)
- CFM stands for Cubic Feet per Hour.
While dentists may be able to answer questions about clinical aspects of a proposed system, they typically lack sufficient information on ventilation or filtration. This is why you need the expertise of ventilation experts such as Total Clean Air to enable you to derive the air volume of your dental practice’s ambient environment.
External Vents Positioning
It is dangerous to vent aerosol with potentially COVID-19 and other infections without proper air filtration.
Generally, ventilation should be arranged to control and remove air contaminated with toxic substances, vapour, or dust before discharging the air outside.
As per HSE COSHH guidance (HSG258 section 220), all potentially hazardous air vented externally must be expelled above the highest point of the roof by use of an appropriate exhaust system.
Aerosol Extraction and Filtration
A virus in aerosol form can remain active up to 48 hours. The purpose of extraction and filtration systems is to remove particulate matter from the air with maximum efficiency and minimum pressure loss in the system.
Total Clean Air Provides Extraction Solution for Dental Aerosols
At Total Clean Air, we supply, install, and maintain air extraction to eliminate aerosols from the dental environment.
Our air extraction system utilises HEPA technology to give you the cleanest, most purified environment possible.
The system is designed to capture all aerosol-generated dust, fumes, smoke, particulate matter and other airborne allergens as small as 0.3 microns from dental offices and other medical facilities prior to exhausting through an HVAC system. The unit offers flexibility in terms of location and ease of use with minimal maintenance.
This fully integrated solution gives you what your practice expects and deserves: outstanding airflow, total clean air and optimal extraction performance.
Features of Our Dental Aerosol Extraction for Dentistry & Orthodontics
The four-stage filtration system provides extraordinary filtration through a HEPA filter, carbon filter, and two-micron filter, providing an outstanding result for dental use. Whether this unit is used in dental, surgical, or other clinical environments, these powerful pressurised systems are for removing particles from the air stream during the procedure.
Powerful, energy-efficient vacuum
The powerful, energy-efficient vacuum with an easy-to-use control panel and lightweight design makes it an ultra-compact tool that helps patients breathe comfortably while complying with safety standards.
Flexible Extraction Arm
The powerful and flexible extraction arm allows contaminants to be captured at the source by means of an internal pump which is activated when the tool is connected to the aerosol extraction system.
Lightweight and easy to move
Our dental aerosol extraction system is designed to be lightweight and easy to move from room to room. The base unit allows for greater mobility. The user-friendly controls make operating simple.
Our dental aerosol extraction system offers quiet operation and easy adjustment of gentle airstream for optimal patient comfort. This unit is provided with the necessary attachment set for dental or orthodontic application.
The design enables 18% better airflow and 15% higher suction than other aerosol extraction systems on the market.
