Dental caries experience of preschool children from the North Brisbane region.

Abstract

To report the dental caries experience of preschool children within the north Brisbane region and to investigate the association between selected social and demographic variables and disease presence. A cross-sectional sample of 2515 children aged four to six years was examined in a preschool setting using decayed, missing, filled teeth/surface (dmft/dmfs) and percentage caries free indices. A self-administered questionnaire obtained information regarding selected social and demographic variables. The data were analysed using the chi-square and one way analysis of variance procedures at the 5 per cent level of significance. Overall, 1668 (66.3 per cent) children were disease free at the examination and mean dmft was 1.4+/-2.77 and dmfs was 2.28+/-6.00. Dental caries occurred more frequently and severely in children from non-Caucasian background (p<0.000), family language other than English (p=0.001) and lower socio-economic status (p<0.000). Significant associations between child ethnicity, language spoken at home, socio-economic status and caries presence have been identified. Epidemiological data can be used for improved public oral health service planning and resource allocation within the region.
