This project aimed to develop a preventive approach to aerosol control during ultrasonic scaling by reducing aerosol formation at the point of generation, rather than relying on mitigation strategies after airborne dispersion has occurred. Aero-NOVA is a viscosity-modified coolant formulation engineered to alter fluid behaviour during ultrasonic activation, reducing fragmentation and suppressing the generation of respirable aerosol particles. The project involved the development of a bespoke environmental testing chamber and simulated dental surgery model to enable controlled aerosol characterisation during instrumentation. Validation incorporated high-speed imaging to analyse coolant dynamics and cavitation behaviour, alongside multiple real-time particle sensors positioned around the operative field and simulated patient to quantify particles <5 µm. The studies demonstrated significant reductions in respirable aerosol production compared with conventional coolant systems, while maintaining ultrasonic functionality and biofilm removal efficacy. Three patents have been granted as part of the project. The next phase of the work involves first-in-human clinical evaluation and progression through the relevant medical device regulatory and classification pathways.
