The UK public and healthcare professionals' awareness of mouth cancer.

As the rate of new mouth cancer diagnoses continues to increase in the UK, awareness of risk factors and signs and symptoms remains low. This paper focuses on studies showing UK public awareness of risk factors, including alcohol, tobacco and human papillomavirus, as well as public understanding of signs and symptoms of mouth cancer. It includes a review of the effectiveness of campaigns in raising awareness of mouth cancer and examples of campaigns targeting other common cancers or risk factors that may provide useful learning ahead of upcoming mouth cancer campaigns. In addition, the awareness of the wider healthcare team and the importance of their role in identifying mouth cancer is explored. Current live campaigns in the UK are highlighted ahead of future initiatives now that the Mouth Cancer Action Charter has been launched and two new coalitions have been established.

When (and when not) to use the Dahl Concept.

The Dahl Concept describes the re-establishment of occlusal contacts after the provision of a planned localised appliance or restoration in supraocclusion. Initially developed to create space for prosthetic rehabilitation of anterior teeth suffering from localised wear, the principle has later been successfully applied to a variety of situations, including the Hall technique and resin-bonded bridges cemented in supraocclusion. Despite high levels of success seen in the relevant literature and widespread adoption in specialist care, the wider profession appears to be far more cautious in its use. This article aims to provide a brief summary of the Dahl Concept and discuss the local and general factors that influence its successful implementation in the hope of promoting its increased adoption by the broader dental profession.
