Abstract

Geo-mapping of caries risk - for allocation of preventive care
Track: Health and Human Services
Authors: Fredrik Davidsson, Anders Holmén

Dental caries is unevenly distributed within populations with a higher burden in low socio-economy groups. Thus, tools are needed to allocate resources and establish evidence-based programs that meet the needs of those at risk. The aim of this project was to apply a novel concept for presenting epidemiological data based on caries risk, using geo-maps. Each study individual was geo-coded with respect to his/her residence parish. Smoothed caries risk geo-maps, along with corresponding statistical certainty geo-maps, were produced by using ESRI® ArcGIS extension Rapid Inquiry Facility and the ESRI® ArcGIS system.
The geo-maps displayed obvious geographical variations in caries risk. With increasing age the gross geographical risk pattern persisted. Geo-maps based on caries risk may provide a novel option to allocate resources and tailor supportive and preventive measures within regions with sections of the population with relatively high caries rates.
