The aim of this study was to investigate possible risk factors for dental caries in primary school children.


Children aged 10-12 years (n = 257) residing in Lithgow, a non-fluoridated community in New South Wales, Australia, were examined for caries experience in the permanent dentition. Information on dental practices, diet, residential movements, and socioeconomic status were obtained from self-completed questionnaires.


Caries risk in the permanent teeth was associated with social disadvantage and diet. Among the dietary factors, the frequency of fruit consumption was associated with higher odds of caries experience (odds ratio: 1.52, 95% confidence intervals: 1.05, 2.21).


Exposure to a high level of fruit consumption was suggestive of increased caries risk. Longitudinal studies are required to investigate the relationship between fruit consumption and dental caries.
