The team includes academics and researchers in orthodontics, health psychology, ethics, paediatric dentistry, sociology, dental public health and social policy.

Our unique strengths enable us to produce innovative and world-class theoretical and methodological-oriented research that makes significant contributions to academic debates across disciplines as well as clinical practice. Our person-centred approach to oral health and dental research is exciting and groundbreaking both nationally and internationally.

Principal aims

The aim of this research group is to plan, conduct and implement high quality research in oral health utilising the theories and empirical traditions of Dental Public Health, Sociology and Psychology with the purpose of improving the oral health of individuals and populations.

Our novel and interdisciplinary research bridges the gap between the theoretical and methodological traditions of the social sciences and clinical specialities to highlight and advance a person-centred approach in the field of dentistry. The group’s expertise is in a number of areas working across a number of levels; individual, group, society and health services; encompassing a range of methodologies, from traditional quantitative approaches (epidemiology, psychometrics) to more innovative qualitative paradigms (systems theory, narrative).

Objectives

• To explain the experience of oral health and disease from individual and population perspectives.
• To explore the structural and psychosocial aspects of oral health.
• To identify ways in which the oral health of individuals and populations can be improved.
• To contribute to national and international academic debates in dentistry and social sciences applied to oral health
• To develop innovative and enabling research methods in relation to oral health

Patient-reported oral health measures

Dentine Hypersensitivity Experience Questionnaire

Funded by: Glaxosmithkline

The DHEQ was developed by a team of researchers, including Sarah Baker, Barry Gibson and Peter Robinson at the School of Clinical Dentistry with funding from Glaxosmithkline. It has been widely used since 2010 in clinical trials, research projects and population surveys. There are currently two versions; the DHEQ consisting of 34-items which assess functional restrictions, social impacts, coping adaptations, emotional impacts, and identity impacts as a result of dentine hypersensitivity. The second version which is available is the DHEQ-15 short form.

Publications relating to the DHEQ and DHEQ-15 include:

There is evidence that the appearance of the teeth can adversely affect the social and emotional well-being of young people, particularly during adolescence. We propose to carry out a study following a group of young people, aged 11 to 16 years, who are having braces in five centres (one busy specialist orthodontic practice, one busy district general hospital orthodontic department and three dental teaching hospital orthodontic departments). The objective is to see how treatment affects OHQoL. Data on OHQoL, clinical changes, self-esteem and socio-economic status (based on home postcode) will be collected at the start of treatment and at the first retainer review, 3 to 6 months after the brace has been removed. We also propose to follow participants up for a year after their braces have been removed. In addition to looking at changes in OHQoL, we will investigate the relationships between clinical status and other factors according to two models of health.

Development of an orthodontic appliance (brace) impact questionnaire.

Incomplete orthodontic treatment represents a considerable waste of time and money to the young people, their parents, clinicians and the NHS. Investigating the impact of orthodontic appliances on young people might give some insight into why some young people cannot tolerate orthodontic appliances and give up part way through treatment. The aim of the study is to obtain the views of young people about how their orthodontic appliance affects their everyday life and incorporate these views into a new impact of orthodontic appliance questionnaire. We also plan to undertake some initial cross-sectional testing of the measure. The design will be a mixed-methods approach, involving firstly qualitative interviews with young people aged 11 to 17 years, to identify items to include in the questionnaire. This will be followed by validation of the items and cross-sectional testing, using psychometric analyses of test-re-test reliability, internal consistency, interpretability and content, criterion and construct validity. Item reduction and analysis of differential item functioning will be achieved through Rasch analysis.

Resin-modified glass ionomer or composite for orthodontic bonding?

Demineralization during orthodontic treatment is a common clinical problem. A recent systematic review has shown little evidence that current methods of delivering fluoride are effective at reducing this problem. The design is a multi-centre randomised single blinded controlled clinical trial will be conducted with two parallel groups. Participants were treated by six specialist orthodontists in both hospitals and specialist orthodontic practices. The interventions were bonding all teeth in front of the first permanent molars with either a resin-modified glass ionomer cement (Fuji Ortho LC) or a light cured composite control (Transbond). The two main outcome measures are difference in demineralization of the anterior teeth before and after treatment assessed from photographs and the number of debonded brackets during treatment.
