PhD Why is brushing teeth so hard? An exploration of oral hygiene behaviours to identify key drivers for change

About the Project

Despite improvements in recent years, dental disease remains prevalent in pockets of the general population with variations across the country. Dental decay can cause unnecessary pain, sleepless nights, and loss of productivity and result in significant costs for individuals and the health service. Recent inability to secure dental access further exacerbates the problem. Individual behaviours including frequent brushing with fluoride toothpaste and limiting sugar consumption are crucial for preventing dental decay from occurring and slowing down the progression of the disease. If individuals follow these beneficial behaviours, they can look after their teeth for life. Despite their importance, we know that individuals still face difficulties in following oral hygiene behaviours. Also, despite increasing knowledge around oral health behaviours we still lack in-depth understanding of the behavioural determinants influencing oral hygiene practices and the interplay between them and wider determinants of health. The main aim of this PhD opportunity is to explore and increase our understanding on why some individuals might struggle to follow beneficial oral hygiene behaviours. To achieve this main aim, a mixed methods approach is envisioned following key behavioural theories and frameworks. The following objectives will be in place: (a) mapping toothbrushing behaviour and oral hygiene behaviours using established behavioural frameworks to understand how the behaviour is first conceived, how it unfolds and what happens afterwards, (b) building on mapping exercise, use theory to explore the most appropriate behaviour change techniques to deliver lasting behaviour change to improve oral health outcomes, (c) understand mechanisms of action to tailor and target interventions to support oral hygiene behaviours and to improve oral health

Eligibility

Applicants are expected to hold (or be about to obtain) a minimum upper second-class honours degree (or equivalent) in psychology, public health, child development sciences, and other health-related disciplines. Experience in quantitative research (data collection and analysis) as well as qualitative research methodologies will be very welcome. Interest in applying theories of behaviour change, psychology-applied to dentistry and a general understanding of key frameworks will be very welcome.
