Objective: To develop and evaluate NHS-based strategies likely to improve dental health and reduce inequalities in pre-5-year-old's oral health in Greater Glasgow, Scotland, by ecological study of community-based oral health promotion programmes in two of the area's most socio-economically deprived communities.
Basic research design: Following an initial health service-based Oral Health Needs Assessment (OHNA) in a severely deprived community, culturally relevant dental health promotion interventions were initiated with multidisciplinary collaborative networks. Ecological studies to monitor dental health involved cross-sectional caries epidemiology of nursery children aged 36-59 months at baseline (1995/96), after two (1997/98) and four years (1999/00), in the G22 (pilot) and G33 post code areas. These areas had similar socio-economic status (SES), i.e. severe social deprivation.
Results: At the outset, mean dmft scores in the pilot area for the age groups 36-47 months and 48-59 months were respectively 3.9 (95% CI 2.8 5.1) and 5.9 (95% CI 5.1-6.8), with the proportions of caries-free children being 38% and 17%, respectively. Reductions in mean dmft of 46% for the 36-47 month-olds and 37% for the 48-59 month-olds occurred in the pilot public health programme area over the four-year period; the proportions of caries-free children increased to 51% and 40%, respectively. During the first two years of the programme, increases in the mean dmft of 36-47 month- and 48-59 month-olds in the G33 (comparator) area were recorded. However, this trend was reversed significantly two years later following the introduction of a similar community development-based caries-prevention programme.
Conclusion: While not being able to attribute causation, a programme of community development to promote the dental health of pre-school children residing in two socio-economically disadvantaged areas of Glasgow was associated with significant improvements in the dental health of these pre-school populations.
