Dental patients and practitioners could be better protected from COVID-19 and other airborne viruses and bacteria thanks to the development of a new environment-friendly shield by a multidisciplinary team from the University of Bristol and University Hospitals Bristol and Weston NHS Foundation Trust (UHBW). The shield could also increase the number of patients seen by dentists and help reduce procedure wait times.

The device, called NoPaS (Novel Patient Shield), is designed to protect patients and practitioners from harmful diseases including COVID-19, which can be spread through aerosols generated during dental procedures.  The device could also significantly cut clinical waste, including the use of disposable personal protective equipment (PPE).

Dr Mojtaba Dorri, Consultant in Restorative Dentistry in the Bristol Dental School and University Hospitals Bristol & Weston NHS Foundation Trust (UHBW), who led the development of NoPaS, said: “During the COVID-19 pandemic the development of innovative environmentally-friendly solutions have been much needed to allow routine dental care to be delivered in a safe environment without risking virus transmission. With the virus still circulating and the chance of future pandemics, it is important routine dental care continues to ensure public oral health is not affected. 

"With minor modification, NoPaS can be used for medical procedures on the head and neck, including endoscopy, anaesthetics and ear, nose and throat.      

"Thanks to the Elizabeth Blackwell Institute, MRC Confidence in Concept and Bristol and Weston Hospitals Charity (formerly Above & Beyond) grants, our NoPaS prototype has been fully tested.   With the device now patented, we are actively seeking partnerships to take NoPaS into mass production."
