Abstract
In September 2009, members of the newly redeveloped Primary Care Dentistry Research Forum (http://www.dentistryresearch.org) took part in an online vote to identify questions in day-to-day practice that they felt most needed to be answered with conclusive research. The question which received the most votes formed the subject of a critical appraisal of the relevant literature. Each month a new round of voting takes place to decide which further questions will be reviewed. Dental practitioners and dental care professionals are encouraged to take part in the voting and submit their own questions to be included in the vote by joining the website.
This paper details a summary of the fi ndings of the second critical appraisal. In conclusion, the critical appraisal has identifi ed that the most effective approaches for increasing dental attendance in families from deprived areas were the mobile dental unit at school premises and the dental access centre. The fi ndings conclude that more high quality research is needed to determine the best ways to address the widely-acknowledged unmet treatment need of children and families in lower socioeconomic groups.
Background
Socioeconomic factors are key determinants of oral health inequalities.1 Children from low socioeconomic status families in the UK show higher caries prevalence, fewer caries-free teeth, fewer sealants and more untreated lesions.2,3 Regular dental attendance is associated with better oral health4 and quality of life (QoL).5 Fifty-nine percent of adults (1998)6 and 62% of children (8 years old, 2003)7 regularly attend the dentist, with 26% of the latter only attending when in trouble. Regular dental attendance is more prevalent in high socio-economic groups.8,9
The Department of Health's Dental Access Programme10 aims to address perceived and actual barriers to NHS dental care by 2011. The Steele Review11 raises the prospect of a fundamental re-orientation of NHS dentistry to an oral health service. Future NHS primary care trust (PCT) commissioning of dental services may increasingly extend beyond the dental surgery, customised to meet local population need.12
Aim
This review aimed to identify and summarise primary research studies which evaluate the effectiveness of different approaches for increasing dental attendance by families from deprived areas in the UK.
Review Method
Ovid MEDLINE was searched (1950 to week 4, September 2009) using the search terms 'attendance/health services accessibility' and 'socioeconomic factors/poverty/deprivation' combined with 'dentist'. The search was limited to dental journals and to the UK. One hundred and sixteen papers were identified and 110 excluded. Further searches included CEBD, Cochrane Oral Health Group, CRD, ADA and National Library for Public Health. Six of the studies reviewed either contained explicit change in service provision/approach targeting lower socioeconomic/deprived areas/areas with treatment need, or a more general attempt to increase use of dental services/registration by people who need care, but where the take up of the service from people of different socioeconomic backgrounds is reported. Literature searches were complemented by contact with the Department of Health Dental Access Programme.
Findings
There was only one reported study relating to approaches used by traditional general dental practices to increase dental attendance. The studies found evaluated school dental screening,13,14 a health visitors and GDPs collaborative,15 a mobile dental clinic on school premises as part of school dental screening,16 a dental health promotion display in a shopping centre17 and a dental access centre18 (Fig. 1).
Within these UK studies the quality of evidence was low, with observational approaches dominating and methodological or analytical limitations being identified in each study, weakening the conclusions made (Table 1).
Advice provided by health visitors to mothers of new infants in areas of high social deprivation led to a sustained increase in dental registration, although the effect did not extend to older pre-school children in the household. Three studies in children were all focused upon school dental screening. A 'new model' of dental screening with specific referral criteria led to reduced referral rates in both affluent and non-affluent children, but children with a high index of multiple deprivation (IMD) were more likely to be referred (23% vs 9%). Of those referred, high IMD children were less likely to attend (39% vs 62%) and were less likely to receive treatment for caries in permanent dentition (16% vs 34%).
In the second screening study, an increase in dental attendance was reported across all social classes in the intervention group (45% in intervention group vs 27% in control), and especially in the higher employed group.
The children-focused approach perceived in this review to be most effective in increasing acceptance of treatment, attendance and completion of treatment was the use of a mobile dental unit in school grounds. Half of these primary school pupils from a deprived area had not previously seen a dentist. Testing the actual effectiveness of this approach would require a larger scale study.
Provision of a dental health display targeted at adults in the shopping centre serving a deprived area produced a statistically significant increase in the number of parents taking their children to the dentist.
Dental access centres (DACs) were found to provide treatment to more adults from a disadvantaged background (IMD mean score 38 vs 23) who were more likely to be smokers, to have worse oral health, to be more likely to attend only when in pain, to be less likely to view dental attendance as important, to be under 35 years old and to be dental charge-exempt.
In summary, the two approaches that appeared to be most effective in increasing dental attendance in families from deprived areas were the mobile dental unit at school premises and the dental access centre. Both responded to the particular attendance preferences of the populations served, which may have implications for PCT service commissioning. However, there is a need for more high quality research to determine the best ways to address the widely-acknowledged unmet treatment need of children and families in lower socioeconomic groups.
