The ongoing COVID-19 pandemic has changed people's lives in ways that many would not have predicted. In the days, weeks and months since mandatory lockdowns and restrictions came into effect worldwide, people have had to adjust their daily lives in an effort to slow and restrict the spread of the virus - like regularly sanitising their hands, maintaining social distancing in crowded places, and wearing facemasks. The latter is contentious for some but has been a necessary deterrent in slowing the spread of this virus. There is potential for utilising technology as a supplementary deterrent and monitoring tool to help detect non-compliance of mask wearing. This research investigates the efficacy of AI for such purposes, exploring the applicability of a Convolutional Neural Network (CNN), for predicting if a person in a real time video feed is wearing a facemask. A dataset of over 10, 000 images was created to effectively evaluate this research. The CNN developed was tested against the validation dataset to evaluate its performance, the model demonstrated 98.47% accuracy on a varied and balanced dataset. © 2021 IEEE.

Silver diamine fluoride (SDF) is applied topically to arrest caries and has an increasing evidence base to support its efficacy, both in the primary dentition and to arrest root caries in older patients. It can be used as a non-aerosol generating procedure and is a simple technique. It has a side-effect of discolouring caries black, a factor which requires discussion with patients and their carers prior to application. Due to its efficacy and simplicity, it is a useful intervention for the management of caries. CPD/Clinical Relevance: Caries is a common condition in the UK, and silver diamine fluoride offers a simple alternative management technique when case selection is appropriate. © 2020 George Warman Publications.
